RS-232 Serial Relay Controller

Our RS-232 Relay Boards are fully E3C complaint, allowing up to 256 NCD devices to share a single RS-232 serial port.  Mix and match up to 256 devices in any combination.  Speak to each device individually or all devices at once.

To control the this Relay Controller,  simply connect a data and ground wire between the Relay Controller and computer or microcontroller. Provide +12 Volts DC to the board, and send ASCII character codes to control the relays.  The Command Set can be found in the Product Manual.

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, LED status lights, and E3C compliance.  Relays 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 the Pro Series Controllers 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.  Four different Pro Series samples are available including Relay Control, Read Status and Timing Features , 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! 


R8XSample1.exe 8 Relay Control Sample 1
The above sample demonstrates control and status read of up to 8 Relays. Compatible with all Pro (NOT ProXR) Series Relay Controllers, Including 4 and 8-Channel SPDT and DPDT Versions.
The above screen shot shows one of the four available fully functioning Pro Series samples that are available with the NCD Component Library.  View all the examples on our NCD Component Library Page.

Desktop Relay Control

N-Button & N-Button Lite is software that allows you to configure buttons to control relays and read the status of those relays without programming. You can also create meters for reading variable input sensors connected to the board in real time!  N-Button will allow you to create unlimited widgets and N-Button Lite will allow you to create up to 8 widgets.

Relay Button widgets turn relays on/off directly. It has never been so easy to control relays before.
 
Relay Status widgets show status of the relay automatically right on the desktop!

N-Button Lite is available as a free download. Look for the Desktop Control section to the right to download.

N-Button Lite version supports up to 8 widgets. If you want to add more than 8 widgets, you need upgrade to the standard version.
