PCS-9641 Motor Relay
  • The PCS-9641 relay is a protection, control and monitoring unit for various kinds of motors on solidly grounded, impedance grounded, Peterson coil grounded and ungrounded system.

    The PCS-9641 features high performance functional library, programmable logic, configurable I/O and integrated frequencytracking. This relay is designed based on advanced multiprocessor platform, fully complying with IEC 61850 station bus & process bus, supporting IEC 61850-8-1 MMS and GOOSE.
