RS-232 Serial Relay Controller

This relay controller was developed for users with low-current, low-signal switching applications such as telecommunications, networking, video, line-level audio, and much more.  This relay is equipped with terminal blocks for the convenient connection of electronic devices.  This controller also has an onboard serial and power connector.  Simply connect the power and serial cables and start sending commands.  Power supply and serial cable are available during checkout.  This device uses DPDT relays.  A single DPDT relay is made up of 2 SPDT switches. So each relay acts as two switches that are activated at the same time. This allows two independent signals to be switched at one time.  In effect, there are two independent switches on a single DPDT relay.

Features include no-click startup and LED status lights.  Relays can be controlled at 9600 baud and the board is compatible with ANY computer or microcontroller capable of delivering RS-232 data.  Even a no-frills design deserves a high-quality driver stage, and that’s exactly what we put on this Relay controller.  Fast-reacting flyback diodes help shunt dangerous voltages away from the driver circuit.  To control this Relay Controller,  simply connect a data and ground wire between the board and computer or microcontroller. Provide +12 Volts DC to the board (available at checkout), and send ASCII character codes to control the relays. Connect this board to the USB port of your computer using a USB to Serial adapter.  The USB to Serial Adapter is available at checkout.
