Power supply: 88-300 volts DC.
Frequency: 48-62 Hz.
Analog outputs: Eight 4-20 mah analog outputs.
Protection function: When the current, voltage and other parameters in the power system exceed the set value, the relay protection device will quickly act to cut off the fault circuit or issue an alarm, so as to protect the safety of the equipment and system.
Protection Functions: Includes motor overheat protection, motor start monitoring, rotor stall, phase-to-phase overcurrent, undercurrent, negative sequence protection, zero-sequence current, and circuit breaker failure protection1.
Communication Interfaces: REF610 has two independent communication interfaces, RS-485 or fiber optic interface. Supports protocols such as MODBUS RTU/ASCII, IEC60870-5-103, DNP3.0, and SPA1.
Fault Recording: REF610 has an integrated fault recorder module with four analog input channels and up to eight user-selectable switch channels for complete fault status recording1.
Self-Diagnosis: The self-diagnosis function can determine the relay’s condition and issue warning signals before failure1.
