COM0003 2RAA005844A0006A

Configuration
Isolate RS485 serial port channel
Standard terminal block lead out, running IEC 60870-5-101 serial port remote control Modbus RTU； The baud rate is adjustable from 9.6k to 115.2k, with a maximum bus length of 1200m and 1500VAC electrical isolation to resist strong electromagnetic interference from substations
IRIG-B standard timing interface (core upgrade point)
Independent hardware clock synchronization channel, connected to the unified clock source of the entire station, to mark high-precision time scales for remote signaling, telemetry, and electrical measurement, meeting the requirements of recording the sequence of SOE events in power dispatching
10/100M RJ45 Ethernet
Support IEC 60870-5-104, Modbus TCP network remote transmission to dispatch master station
Backplane bus: Standard 6U VME bus, high-speed exchange of measurement point data with Advant main control CPU
Support communication protocols
Main protocols for power remote control: IEC 60870-5-101 (serial port), IEC 60870-5-104 (Ethernet)
Auxiliary protocols: Modbus RTU/TCP, IRIG-B time synchronization
Compatible with multiple master station scheduling links, capable of simultaneously connecting to multiple scheduling backends

Application
Upload remote control data from the main control of thermal power plants and hydropower stations to regional dispatch
SOE event recording and high-precision timing scenario of substation integrated automation system
Replacement of old Advant DCS renovation spare parts for power projects with high time requirements
