PCS-9794 is a protocol converter designed for the highest standards of performance, safety and reliability to meet requirements of a complex substation automation system (SAS). As an integral part of the SAS, it works as a communication manager, which maps signals between IEDs and the local SCADA or protection management unit.

PCS-9794 transmits data to local SCADA or protection management unit through the IEC 61850 or IEC 60870-5-103, etc. protocols, and links IEDs with protocols such as Modbus through different kinds of communication interfaces.
• Protocol conversion
PCS-9794 can adapt to the signal conversion need of different projects and realize the data exchange between station level and bay level network communications.

• Information acquisition of relay, meter and other IED
Through its serial ports and Ethernet ports, this device can communicate with relay, meter and other IED to gather their information such as SOE and operation signal.

• Communication
This device can communicate with local SCADA and protection management system.

This device can communicate with RTU to realize the data transmission to dispatching center or distributed control center.

The mapping transmission tables for SCADA or RTU can be customized independently.
