The System Sensor PR-1 Multi-voltage Relay is used for high-current switching applications such as fan and damper assembly control, door control, air handling unit controls, and other types of system interfacing. Also, System Sensor PR-1 is epoxy encapsulate multi-voltage relays. Besides, they are single-pole double-throw relays that use a red LED as a visible indication of relay coil energization. Furthermore, the PR–3 is identical to PR–2, except it has an extra pair of wires for redundant power input.
