Functional features

1. Multi-protocol communication and high-speed data exchange

GE The UR67H digital I/O module provides triple independent Ethernet ports and diversified industrial interfaces to achieve seamless integration with protection relays and SCADA systems, supports PRP (Parallel Redundancy Protocol) and direct I/O expansion, and ensures millisecond-level transmission of key instructions.

2. Advanced monitoring and diagnostic capabilities

The module has a built-in 1024 event recorder and configurable waveform capture function, combined with circuit breaker status monitoring (such as arc current I²t analysis and re-impact detection), giving the GE UR67H digital I/O module the ability to diagnose the health status of power equipment in real time

3. Integrated protection and control logic

Supporting phase differential protection, adaptive distance protection and stator ground fault detection, the GE UR67H digital I/O module implements graphical logic programming through the EnerVista software platform to simplify the deployment and debugging of complex protection strategies

4.High-precision power metering

Provides voltage, current, power, harmonics and other 50+ power parameter metering, synchronously supports phasor measurement unit (PMU) function, and provides a synchronous data source for the wide-area monitoring system

Application scenarios

Power system protection: used for substation bus differential protection, transmission line phase current differential and generator 100% stator grounding protection

Industrial automation: factory power distribution automation control, circuit breaker status monitoring and fault location, supports SOE (event sequence recording) and digital fault recording

Predictive maintenance: optimize the operation efficiency of power grid assets through harmonic analysis and load trend prediction
