Product Description
The GE Multilin UR6AV Relay Digital I/O Module is a functional expansion component designed for the GE Multilin UR Series Universal Relay platform. From a real user's perspective-especially for protection engineers and substation maintenance teams-this module is not just an accessory, but a practical extension that determines how flexibly a protection relay can interact with field equipment.
In modern power systems, protection relays must do more than detect faults; they must also communicate with breakers, alarms, SCADA systems, and auxiliary control circuits. The GE Multilin UR6AV Relay Digital I/O Module is designed exactly for this purpose, providing additional digital input and output capability to ensure reliable signal exchange between protection logic and external devices.
