Description

Web Relay Controller Boards from NCD

Our Web Relay Boards make it easy for you to control relays and monitor inputs using any web browser or software. A Web Relay Board allows you turn relays on or off, create macros to send multiple commands, monitor inputs, and write your own software to do any of these things and more with your own software. This Web Relay Controller is a ProXR Lite series controller which is a widely adopted standard used by industry for many years.  Equipped with your choice of 1, 2, 4, or 8 on-board relays, the ProXR Lite series Web Relay Controllers suit the needs of most of our customers.  Integrated Analog to Digital Converters may be used to manually control the relays, or they may be used to read external sensors.  Equipped with 8 or 10-Bit resolution, the ADC built into Web Relay Controllers add tremendous flexibility for various application requirements.

Web Relays relays support DHCP or a Static IP address with a programmable port number, 2101 is used by default.  NCD Ethernet communications module will transmit the IP address of the device using periodic UDP broadcasts, which make it easy to locate the device on a network.

Getting Started with NCD Web Relay Controller Boards

Start by downloading Base Station at https://ncd.io/start and Run the application.  A window will appear which listens for all NCD UDP broadcasts.  Plug in your Web Relay Board and wait for the Network window to populate with the IP address of the Web Relay Board. Enter the IP Address into a Web Browser or double click on the Web Relay Board in Base Station you should be brought to the Web Page for that board. From there you can configure the interface, control relays, or read inputs.

Base Station is a tool designed to teach you all the features built into your controller and provide you with example commands.  Base Station was written for Windows using Visual Studio (source code available on the download page linked above).  Base Station shows you all the commands you need for controlling relays and monitoring external sensors.


New Version Now Shipping

Beginning Late 2020, we’ve made some updates to this product to make it better with increased component count while maintaining the same functionality and footprint.  The New Rev G2 Series adds a better power supply circuit to improve noise immunity while providing increased power to the communications socket.  We also improved the relay drive circuit to better handle inductive loads.  We also changed the color of the circuit board to Black and updated the branding to ncd.io with updated logos.  

This is the same product you have been buying for years, but now with improved electronics and while maintaining the same footprint as the original design.  Most importantly, this is now a Legacy product, which means it will never go obsolete as long as critical parts are still available to us.  Built with our new high-speed pick and place assembly line, we can complete the surface mount assembly process at a rate of several thousand units per day with the potential to scale to any volume you could imagine, so you never need to worry about supply quantities or supply chain problems.

Please note that it was necessary for us to remove the integrated temperature sensor in select versions of this product.  This sensor was providing incorrect readings if the relays were active for extended periods of time.  We can help you with an off-board sensor if needed.

AD8 8-Channel 8/10-Bit Analog to Digital Converters

ProXR ADC
ProXR Analog to Digital Inputs are used to Read External Sensors or Manually Control On-Board Relays

This controller is equipped with 8-Channels of 8/10-Bit Analog to Digital Converters, capable of reading analog voltages from 0 to 5 Volts DC.  The ADCs on this controller allow monitoring of external sensors or contact closure input detection.  Connect external temperature sensors, light sensors, current sensors, buttons, switches, or anything else that generates a 0-5VDC analog or contact closure output.  With 8-bit resolution, analog inputs will convert 0-5 Volt signals into a value from 0 to 255.  With 10-bit resolution, values of 0 to 1023 may be measured.  Input resolution is software selected.  Simply ask the controller for the analog value of each input, and the controller instantly responds.

Relay Activator and Analog Inputs

The Relay Activator control panel allows analog inputs to directly control relays.  Simply connect the analog inputs to buttons or switches and trigger basic relay on or off functions to take manual control of the on-board relays.  The Relay Activator control panel allows you to define 8 functions for each of the 8 inputs.  Functions include turning relays on or off, toggling the state of relays, momentarily flash a relay, momentarily toggle the flashing function of a relay, turn all relays on, turn all relays off, and push notification events.  When push notification events are configured, the controller generates a packet of data every time the inputs change state.

ProXR Quick Start Guide

Online Manual for ProXR and ProXR Lite Series Controllers

Good to Know!

NCD ProXR Series Controllers have been in production for many years and have amassed a large user base since their initial release in the early 2000s. Due to the large client base, we have no plans to discontinue this line of products. In many cases, we are upgrading these devices to make them compatible with automated assembly processes along with improved driver and power electronics capable of supporting many communication technology changes well into the future. Rest assured, ProXR will continue to be a stable part of our product line for many years to come. ProXR series controllers manufactured with a Black circuit board have been migrated to automated assembly and are considered to be the final iteration of this product. These devices can be manufactured in high volumes in a much shorter period of time.

LabVIEW Relay Control

LabVIEW ProXR Relay Drivers
ProXR Analog to Digital Inputs are used to Read External Sensors or Manually Control On-Board Relays

NCD supports integration of NCD relay controllers using LabVIEW.  We have included samples and drivers for basic and advanced operation which cover most functions including Relay Timers.  We have posted several tutorials on this topic here.

ProXR Lite Communication Options

We take communications seriously, as we believe in modular communications and firmware that properly supports scalability into future interface technologies.  ProXR controllers support API communications, which effectively wrap every command with a header, payload, and checksum to ensure reliability.  NCD API commands increase processing speed because no serial timeout is required prior to command processing.  NCD API commands increase reliability, as only a proper checksum will authenticate a command and allow it to process.  When we first implemented API, internet communications via a TCP/IP socket could be realized because the timing problems of internet communications were eliminated.  While API is optional, it is strongly advised.  Our Base Station software uses API communications, so it’s possible to control a ProXR controller over the internet after configuring port forwarding on your router.

ProXR series controllers are the world’s most adaptable controllers, capable of communicating with a wide variety of communication options.  Pick any of your favorite communication technologies: Bluetooth, USB, WiFi, Ethernet, Key Fob, RS-485 or RS-232. ProXR easily adapts to the communication technologies you need most.  We are committed to modular communications, so your ProXR series controllers can easily be retrofitted for other applications as your needs change.  ProXR controllers are never obsolete, as we are actively releasing new communication technologies that greatly enhance the connectivity of our ProXR series controllers.

Relay Options


10a_spdt_relay

10-Amp SPDT Signal Relay Option

This controller is available with a 10-Amp relay option, allowing control of higher-power loads up to an absolute maximum of 240VAC at 10 Amps. Ideal for general purpose switching applications, this relays is focused on power-switching, and should never be used for low-power signals due to a higher On resistance of up to 150 Ohms when relay contacts are new (contact resistance drops to less than 1 Ohm after break-in period). The 10-Amp relay is of the SPDT variety, which provides Common (C), Normally Open (NO), and Normally Closed (NC) connections. Common is connected to NC when the relay is off. Common disconnects from NC and connects to NO when the relay is activated.  All connections are made via screw terminals, capable of accepting up to 12 AWG wire. Review Datasheet

5a_SPDT_relay

5-Amp SPDT Signal Relay Option

This controller is available with a 5-Amp relay option, allowing control of higher-power loads up to an absolute maximum of 240VAC at 5 Amps. Ideal for general purpose switching applications, this relays is focused on power-switching, and should never be used for low-power signals due to a higher On resistance of up to 150 Ohms when relay contacts are new (contact resistance drops to less than 1 Ohm after break-in period).

Compatibility

AD8 Analog Input Usage Notice

Analog Inputs should not have a voltage present when powered down.  Use a 220 Ohm current limiting resistor on each input to prevent damage to the controller if voltage will be present on the analog input when this controller is powered down.  Do not exceed 0 to 5VDC on any analog input or the on-board CPU will be damaged.  Most analog inputs include a 10K Pull Up/Down resistor to help keep the inputs quiet when not in use.  This 10K resistor may slightly bias the readings of some sensors.

Ethernet TCP/IP Compatibility Notes

This device periodically sends UDP Packets on port 13,000, which help identify the IP address of this device on your network.  This device sends UDP Packets to link.signalswitch.com to help users access this device from the internet (this feature can be disable).  Remote access over the internet requires users to configure Port Forwarding on the router that is associated with the WiFi communications module.  Port Forwarding is outside the scope of NCD technical support.  Please visit PortForward.com for instructions on configuring most routers for port forwarding.

Custom IoT Electronic Design Services Process

Most of our users purchase off-the-shelf hardware for initial testing.  Once everything is working, they contact us to build a custom solution which may include specialized changes to the board, firmware, connectors, etc.  Custom boards have many advantages such as reduced wiring, easy installation, small size, less power consumption, and in some cases, an overall reduction in product cost.  Custom IoT Electronic Design Services will have your company name and logo on the board as well as the enclosure.

Customized IoT Electronics

NCD engineers can help build a customized solution for your particular application based on the designs you see on our website.  We can combine devices onto a single board, change the shape, or even some of the components to meet your exact needs.  We also provide turn-key metal enclosures with powder coating and full-color printing on the top side starting at just $500 for setup!  We have more than 20 years of experience in electronics design and manufacturing.  All of our products are designed and manufactured in the USA, so we are here to support the products we make.  We only ask that our customers prototype their needs using our existing products before we customize.

Customization Guidelines

  • Custom designs should be based on our existing product because we can’t build rockets or electric cars over here!
  • We do not provide customization services if it involves the introduction of a new or untested technology.
  • Custom engineering fees depend on your requirements, so please contact us for a quote!
  • We maintain ownership of all designs, including our customized designs as they are based on our existing Design.
  • We will only ship the customized product to you or your authorized agents.
  • We have an NDA available if needed.
  • The turn-around time is about 2-3 weeks.
  • We specialize in low-volume designs, no quantity is too small!
  • We have the ability to scale to large volumes as needed.

Getting Started with Product Customization

All you have to do is contact us and we will walk you through the process from beginning to end, based on your individual needs.  Some people are surprised at how fast we finish CAD design (usually a few hours), but keep in mind, we still have to build your design, which takes considerably more time.  When we customize product, here are the general services we provide:

  • We design the circuit board.
  • We communicate with our customers throughout the customization and manufacturing process.
  • We manufacture surface mount stencils and circuit boards.
  • We program our pick and place machines to build your boards.
  • We build a working sample and run it through our wave solder machine.
  • We test your custom IoT solution.
  • Once the design is finalized it won’t be possible to make changes during production (changes cost money and require us to repeat the above processes)
  • Once it meets all your requirements, we will start production as needed.
  • We work with our metal fabricators to design a metal enclosure if required.
  • You work with our artist to print the top side of the enclosure in full color with your company logo if required.
