Controllers That Stand Above The Competition

Our RS-232 32-Relay Controllers are large, powerful, and very easy to use. Few companies offer relay controllers of this size and we believe our 32 relay controller stands far above the competition.  You can send commands to activate relays, deactivate relays, control all the relays at one time, plus you can send commands that tell a relay to turn on for a few seconds, minutes, or hours.  You can assign 16 timers to any of the 256 relays, and set the timers to go off after the duration has expired.  We have also added a Server Reboot Pulse timing feature that is particularly useful for rebooting up to 16 servers.  With features like these and 32 Relay Channels, it no wonder we stand above the competition!

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.
