8 Channel RS232 Relay

Serial Relay  RS-232 Relay Board

Powerful Commands

Our 8 Channel RS232 Relay Controller offers a powerful command set allowing computer control of several external devices using only a few short commands. Our new and improved command set allows you to set the status of all relays at once or one relay at a time. 

RS232 Switching with a Serial Port

RS232 Relay or Serial Relay Controllers allow computer controlled switching using the Serial port of your computer.  Select NCD Serial Relay Drivers support 8-Channels of 8-Bit / 10-Bit Analog to Digital Conversion (A/D), and include an XR Relay Expansion Port for adding additional relays to the RS232 Relay Controller Board.

Supports any COM Port

An RS232 Relay supports any available COM port at any standard baud rate, allowing easy integration into any program that support serial communications. The RS232 Relay is ideally suited for applications that require data collection and control from a single device. Built-in temperature sensor allows temperature monitoring, analog to digital conversion, and relay control from a single device. RS-232 interface supports baud rates up to 115.2K Baud.

Easy Connection with the Quick Start Kit

The video shows how easy it is to connect an RS232 Relay to the computer with the optional Quick Start Kit.  The R45Pro Quad Relay Controller is shown connected to the optional QS12 Quick Start Kit.
