16 Channel RS232 Relays

RS-232 Relay Boards

Field Tested and Second-To-None

Our 16-Relay controllers are field proven and second to none! If your looking for a sixteen channel relay controller we have a configuration to fit every need.  RS-232 Serial 16-Relay Controllers offer a powerful command set allowing computer control of several external devices using only a few short commands.

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.
