Description

2-Channel SPDT Relay Controller with 8-Channel ADC

This ProXR Lite relay controller is capable of switching 4 on-board SPDT relays, each with 5 or 10 Amps of current, customized at the time of ordering.  Each SPDT relay includes 3 screw terminals for normally open, common, and normally closed contact closure relay output connectivity.  This controller features a modular communications interface, capable of accepting USB, RS-232, Ethernet, WiFi, Bluetooth, Industrial Wireless communication modules, and more.  On-Board Analog to Digital Converters allow monitoring of 8 inputs at 8 or 10-Bit resolution.  Analog inputs are ideal for connecting external sensors, or connect buttons and switches to the inputs and configure the controller to manually control relays when buttons are pressed.  Turn relays on or off, toggle the state of a relay, or trigger relay flashers all from external switches.

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

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.

Base Station Software

Base Station Software was designed to help you learn the ProXR command set.  Explore ProXR features using our Graphical User Interface.  Watch data bytes flow to and from the board, so you easily understand the command execution process.  There is no faster or easier way to learn how to automate than Base Station, as it was designed to work  with our complete array of communication modules, including Wireless, Ethernet, USB, RS-232, and many more.  You only need a Windows 8 or 10 Computer to Run Base Station.  Base Station was written in Visual Studio, and we even provide the source code to help you on your way!

ProXR Lite vs. ProXR Series

ProXR Lite controllers are smaller, surface-mounted variants of the ProXR Series relay controllers.  The firmware is nearly identical between the series with ProXR Lite being limited to 8 relays.  Only the ProXR series includes a XR expansion port for relay expansion.  ProXR Lite controllers are a lower-cost alternative to ProXR because they are machine manufactured in larger quantities.  ProXR series controllers are currently manufactured with through-hole technology and socketed chips, making them field serviceable.  ProXR Lite controllers are available with little as 1 or 2 relays while ProXR Series focuses on applications that require 4 or more relays.

ProXR Lite Communication Options

We take communications seriously, as we believe in a 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, Ethernet Web-i WebRelay, 802.15.4 Wireless, ZigBee Mesh, Key Fob, 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.
