Description
The FSR IT-R4 is a multi-purpose relay module allowing four internal single pole double throw relays to be controlled by a contact closure using a simple ASCII control protocol. Additional IT-R4 modules can be daisy chained to provide control of additional modules or other contact closure devices. The IT-R4 passes contact closure control data out to other contact closure controlled devices via the unit’s contact closure output port. The IT-R4 is capable of supporting a wide variety of relay controlled devices making it an essential tool for AV and control system installations.
Use to control shades, screens, or anywhere relay switching is needed via contact closure.
The FSR IT-PS1 power supply is sold separately, one power supply can power up to 6 IT-R4 or IT-R4S modules saving wiring headaches and money.
