Why Engineers Specify This Model
- High-Density Input Acquisition — Maximizes digital input count per chassis slot, reducing hardware footprint in space-constrained relay panels.
- Seamless UR Platform Integration — Hot-swappable modular design allows field replacement without relay de-energization, minimizing maintenance downtime.
- Wide Voltage Compatibility — Accepts a broad range of wet/dry contact input voltages common in substation DC control circuits (24 V–250 V DC).
- IEC 61850 GOOSE Ready — When paired with a UR relay CPU, digital inputs can be mapped to GOOSE messages for peer-to-peer protection schemes.
- Proven Field Reliability — GE UR Series modules are installed in thousands of substations globally with a documented MTBF exceeding 20 years.
