Description
The FSR IT-R4S is a multi-purpose relay module allowing four internal single pole double throw relays to be controlled by an RS-232 port using a simple ASCII control protocol. Additional IT-R4S modules can be daisy chained to provide control of additional modules or other RS-232 devices. The IT-R4S passes RS-232 control data out to other RS-232 controlled devices via the unit’s serial output port. The IT-R4S is capable of supporting a wide variety of relay controlled devices making it an essential tool for AV and control system installations.
