Integrated standard serial and power connector
Convenient Terminal Blocks for easy electronic connections
Highly Reliable Relay Board For Demanding Applications
This relay is equipped with terminal blocks for convenient connection of electronic devices. This controller also has on-board serial and power connector. Simply connect the power and serial cables and start sending commands. Power supply and serial cable are available during checkout.
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.
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.
This Relay Controller is 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.
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.
