Description

Single Relay with Quick Connect Terminal Blocks

Control One Relay with Two-Way Communication
On-Board Easy RS232 Connection
Highly Reliable Relay Board For Demanding Applications

RS-232 Serial Relay Controller

This simple RS-232 Relay board was designed to offer basic relay control functions using the RS-232 port of your computer.  Supports Relay On and Off commands and reading the status of relay.  Provide +12 Volts DC to the board, and send ASCII character codes to control the relay.  Even a no-frills design deserves a high-quality driver stage, and that’s exactly what we put on our Serial Relay Controllers.  Fast-reacting flyback diodes help shunt dangerous voltages away from the driver circuit.

Features include no-click startup and LED status lights.  Relay can be controlled at 9600 baud and the board is compatible with ANY computer or microcontroller capable of delivering RS-232 data.

Connect this board to the USB port of your computer using a USB to Serial adapter.  The USB to Serial Adapter is to be used with the Quick Start Kit and is available at checkout.

NCD Component Library

Fully functioning programs for R25, R210, R220 and R230 are included with the NCD Component Library. With the NCD Component Library we’ve “started” the programming for you. We say started because these are fully functioning samples but we’ve also included the source code so you can customize them to your exact needs.  The NCD Component Library is a plug-in for the Visual Studio 2005/2008 that greatly simplifies the communications to the NCD product line.  The samples can be run in Visual Studio and fully customizable to your needs.  Two different dual channel samples are available to turn on and off the relays, read the status of the relays and retrieve startup default state of relays.  To view screen shots of each sample visit our NCD Component Library Page.  Start by downloading the FREE NCD Component Library and you will be communicating with any NCD device faster that ever!

The above sample demonstrates control and status read of 2 Relays.  Compatible with all R2x RS-232 Series Relay Controllers.

The above screen shot shows one of two fully functioning dual channel samples that are available with the NCD Component Library.  View all the examples on our NCD Component Library Page.

Relay Options


20A_LowCost_relay

20-Amp SPDT Low Cost High Power Relay Option

This controller is available with a 20-Amp relay option, allowing control of high-power loads up to an absolute maximum of 240VAC at 20 Amps. Ideal for high-power switching applications, this relay should never be used for low-power signals. The 20-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.  This relay is Rated at 20-Amps between NO and C.  Do not exceed 10-Amps between C and NC connections. Review Datasheet

Compatibility

RS-232 Serial Compatibility Notes

The NCD RS-232 Serial communications module is compatible with standard RS-232 signals (+/-10VDC), which are not directly compatible with UART signals from a microprocessor.  If you are working with Arduino, Microchip PIC, or other common microcontroller, a communications module is not required.   Microcontrollers will directly talk to the on-board processor of all NCD controllers.

Serial Cable OptionChange

NCD Controllers are cable of connecting directly to your computer using this optional serial cable.

USB to Serial Converter OptionChange

Add a USB to Serial Converter to control this device over the USB port on your computer. Requires the Quick Start Kit option for plug-and-play operation.

Would you like a power supply?Change

NCD Controllers Need Power. Standard NCD Power Supplies use a 2.1mm Barrel Connector with 12VDC (center positive) rated at 1.25 Amps (minimum).

Do you need Induction Suppression Capacitors?Change

Induction Suppression Capacitors are essential for managing inductive loads such as Motors, Solenoids, and other Electronic Devices that implement a collapsible magnetic field.  These capacitors will reduce the chances of Electromagnetic Interference with our controller and prolong the operational life of relays.


Customize

We Customize Just for You!!

NCD offers many custom IoT electronic design services to help tailor our product to your exact needs.  Whether you are looking for custom firmware, circuit board modifications, metal enclosures, or industrial color printing, we can help you with a wide variety of design services.

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.
