Relay control board

Description

This relay card can be used for many applications: stand-alone mode; addressed by switches or open-collector outputs. It can be controlled remotely via an RS232 serial connection. As an option, remote control is possible using RF (radio frequency) signals and the K8058 remote control kit + an RX433 module. Because the card can be addressed using RS232 commands, you can write applications in your preferred programming language. Test software can be downloaded from the www.velleman.be website.
