Product Overview
The IntelliTools 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.
The IT-R4S passes RS-232 control data out to other RS-232 controlled devices via the unit’s
serial output port. The module is powered from a standard 12 VDC power supply (not
provided). An integral mounting plate with four holes is provided to easily mount on FSR’s RK-
2 rack mount, standard rack rails or standard two RU blank plates. 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.
