Highly Reliable Relay Board For Demanding Applications
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 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. |

Desktop Relay Control
N-Button creates widgets or buttons to control up to eight relays without any programming. A new button will be created and placed on the desktop of your computer for each relay that you want to control. N-Button Lite supports Serial Port/ USB and Network connection between PC and relay board. N-Button Manager makes it easy to add any type of button to the desktop and change the properties.
| Relay Button widgets turn relays on/off directly. It has never been so easy to control relays before. | |||
