Scenario:
Real-time monitoring and protection control for a 110kV intelligent substation.
Configuration:
ARMxy main controller
X-DI module (for circuit breaker/disconnector status)
X-RS485 module (for communication with protection relays)
Implementation:
The DI module collects:
– Circuit breaker auxiliary contact status (110VDC, converted to safe voltage levels)
– Gas relay signals (dry contacts)
RS485 module connects to protective relays and uploads key data to the dispatch master station using supported protocols
Fault waveform data is locally recorded for traceability
OpenPLC handles the control and logical operations
Advantages:
Dispatch centers can remotely view substation status in real time
X-Series DI boards support wide voltage input (-10V to 10V), allowing flexible adaptation to high-voltage contact interfaces
