UR-RLH

Description

UR-RLH is a low power DC power supply module designed by GE Multilin for use in the Universal Relays (UR) series.

Voltage & Power Role

• Operates at 24–48 V DC nominal

• Supplies power to the relay and its dry contact inputs

• Contains the battery for the Universal Relay; must be removed for battery replacement

Fault Protection Logic

• Includes a form-C critical failure relay

• Relay energizes when system boots successfully and passes self-tests

• Relay de-energizes if control power is lost or a critical fault is detected during operation

System Compatibility

• Installs within GE’s Universal Relays platform

• Works alongside other UR modules:

  • CPU module

  • CT/VT module

  • Digital I/O module

  • Transducer I/O module

  • Inter-relay communications module
