Product Overview

The UR7CM is a digital input expansion module used with GE Multilin UR Series (Universal Relay) platforms. It is installed to increase the available discrete status inputs for protection, control, and monitoring schemes, allowing the relay to receive external contact signals such as breaker auxiliary status, lockout indications, alarm contacts, and interlock permissives.

In typical protection and control panels, the UR7CM supports structured wiring of field contacts into the relay environment so that logic, alarms, and event records can be built around real plant and switchgear states. This module is commonly applied where additional binary inputs are required without replacing the base relay.
