Multi-Purpose Switch/Logic Relay IT-R4

FSR's Multi-Purpose Switch/Logic Relay gives AV and control systems a flexible way to trigger relay actions from contact closure or logic-level inputs. The IT-R4 includes four user-configurable relays controlled through five input ports, allowing each relay to be set for on, off, momentary pulse, or toggle operation. It is useful for shade control, projection screen control, speaker muting, logic-level control, relay contact closure, and other room automation tasks. With a small footprint, screw terminals, an integral mounting plate, and support for shared power supplies across multiple IT-R4 or IT-R4S modules, it helps simplify low-voltage control wiring in classrooms, meeting rooms, control rooms, and AV installations

Below is a typical application diagram showing how useful these modules really are:
