GE UR77H Digital I/O Module Industrial Automation Solutions
The GE UR77H is a robust universal relay designed for power system protection and control. Key specs include a 1A/5A current input, multiple communication protocols (Modbus, DNP3), and a wide operating temperature range (-40°C to +60°C). It's typically used in utility substations for transformer and feeder protection. Compared to the GE 369-HI-0-M-0-0-0, the UR77H offers more advanced communication options and a broader temperature range, making it suitable for harsher environments.
