The GE UR6AH is a versatile I/O module designed for use within GE Multilin Universal Relay (UR) systems. It provides flexible input and output expansion capabilities, allowing protection relays to interface efficiently with external field devices.

In a substation automation upgrade project, the GE UR6AH was installed to expand the digital and analog I/O capacity of an existing protection system. During commissioning, the GE UR6AH enabled seamless integration with protection relays, ensuring accurate signal acquisition and reliable control output.

Engineers selected the GE UR6AH for its modular design, high reliability, and compatibility with GE Multilin UR series relays. The GE UR6AH continues to be widely used in power distribution and protection applications requiring scalable I/O solutions.
