FAQs
When upgrading legacy protection relays, verify that the EGR-5000-2B1GB0 supports the same protection schemes and interlock logic. Ensure RS-485 wiring follows the D-Sub interface standard and that the control cabinet has space for semi-flush mounting. Plan for removable terminals to simplify field maintenance and verify the zone selective interlocking configuration aligns with existing generator bank protection.
Key specs include 8 digital inputs, 9 digital outputs, 2 analog inputs, 2 analog outputs, and 2 current sensing inputs. It supports a power range of 19-300 VDC or 40-250 VAC at 50/60 Hz. Communication is via Modbus RTU or DNP3 RTU over RS-485 using a D-Sub connector, with additional I/O options such as Sensitive Ground Input and IRIG-B interfaces for precise timing.
Yes. Its multi-layer protection, high configurability, and RS-485 SCADA compatibility make it suitable for data centers. The device’s digital I/O, analog metering, and zone selective interlocking support fast fault isolation, reducing downtime. Conformal coating and a semi-flush mounting option enhance reliability in mission-critical environments.
