Digital control unit PCS-9705

PCS-9705 Bay Control Unit (abbreviated as BCU) is used for bay level controlling and monitoring in power grid. It is suitable for application in Substation Automation System (abbreviated as SAS) with distributed control IEDs. PCS-9705 can be applied into SAS via Ethernet network in using NR private 103 protocol or IEC 61850-8-1. It can also send/receive Generic Object Oriented Substation Event (abbreviated as GOOSE) message in station level network. PCS-9705 is designed for controlling and monitoring switchgears such as circuit breaker, disconnector, and earthing switch. Additionally, it supports tap changer control for transformer and shunt reactor. • AC analog input (Conventional CT/VT) • AC digital input (Electronic CT/VT, IEC 61850-9-2) • DC analog input • DC analog output • Configurable binary input • Binary output (normally open contact) for switch control and interlocking logic • CB closing synchronism-check
