Features:

  • GE Multilin UR Series
  • Digital I/O Module
  • High-accuracy metering, diagnostics, and data logging
The General Electric (GE) Multilin UR-4DH is a digital input/output (I/O) module for the Universal Relay (UR) family, a series of protection and control devices used for power system management. The module is engineered for high-speed, secure communication and provides enhanced monitoring capabilities to GE Multilin UR relays, often used in utility and industrial applications.

The Digital I/O Communications supplied by the module allow the relay to communicate with other relays and subation equipment digitally, removing the need for auxiliary connections and communication methods. This communication is both high-speed and secure, increasing the overall cyber security of the unit without it coming at the cost of communication rates. By including so many capabilities in one compact unit, the Universal Relays series reduces user costs over time.

The UR 4DH General Electric Digital I/O Module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).
