    Communications
    • Up to four 10Base-T/100Base-TX (RJ45) ports or two 100Base-FX ports with IEC 61850-8-1 MMS and GOOSE for non-time-critical message, IEC 60870-5-103 over TCP/IP or DNP 3.0
    • Two RS-485 rear ports with IEC 60870-5-103
    • Up to Six 100Base-FX ports with IEC 61850-9-2 Sampling Value and GOOSE for time-critical message
    • One RS-485 rear port for clock synchronization
    • One RS-232 rear port for printer
    • 1 faceplate RJ45 port for testing and setting
    • Clock synchronization via pulse, IRIG-B and SNTP
  • Modularized hardware design enables an easy upgrade or repairs. Various optional function modules can satisfy various situations according to the different requirements of users.
  • This device can sample the analog values from the conventional CT/VT, or receive the sampled values from electronic CT/VT via merging unit.
  • Overcurrent protection can be controlled by directional protection, harmonic blocking element and voltage control element.
  • The relay provides optional RTD input module and DC mA input module for temperature detection.
  • This device constantly measures and calculates a large amount of analog quantities, such as phase voltage, phase- to-phase voltage, neutral voltage, phase current, neutral current, active power, reactive power, power factor and frequency etc.
  • The connector type can be selected as plug in/out terminal connector or screw terminal connector. The unique plug in/ out terminal connectors from the relay rear panel to the terminal blocks on the rack or cabinet makes the onsite commissioning and replacement much easier than the traditional screw terminals when you do the commissioning.
  • Various methods of GPS time synchronization are supported in this relay, including SNTP, pulse per second (PPS) and IRIG-B synchronization.
  • This device can communicate with a SAS or RTU via different communication intermediates: Ethernet network, RS-485 serial ports. The communication protocol of this device is optional: IEC61850, IEC60870-5-103 or DNP3.0.
  • This device can detect the tripping circuit of the circuit breaker and monitor the operation (close or trip) time of a circuit breaker by checking the auxiliary contacts of the circuit breaker.
  • Complete event recording function is provided: 64 latest protection operation reports, 1024 latest supervision records, 1024 latest control operation records, 1024 latest user operation records and 1024 latest records of time tagged sequence of event (SOE) can be recorded.
  • The relay is compatible with multiple protocols- IEC61850 and IEC 60870-5-103 for station bus, GOOSE and IEC61850-9-2 for process bus.
  • The setting group can be switched by binary inputs.
