FAQs
Begin with confirming a projection mounting fit and removable terminals for quick access. Ensure the power supply range matches site power (19-300 VDC or 40-250 VAC) and connect RS-485 lines to Modbus RTU or DNP3 RTU as required. Verify the 8 digital inputs and 9 outputs align with protection logic, and reference the ETR-4000 base relay for installation guidance to minimize commissioning time.
The ETR-5000-2A3GB1 supports Modbus RTU or DNP3 RTU over D-Sub RS-485, facilitating easy integration with most SCADA systems. This enables centralized monitoring, event logging, and coordinated trip signaling across transformer protection schemes, improving visibility and reducing mean time to repair in substation and plant environments.
Yes. With 8 DI, 9 DO, 2 current-sensing inputs, and a flexible power-supply range, the ETR-5000-2A3GB1 is designed for transformer protection in substations and industrial facilities.
