Integrated DC Feeder Monitoring Secondary Unit

The IARM-FC80 serves as a secondary monitoring unit for integrated DC feeder monitoring, equipped with a 7-inch touch screen. It mainly performs DC bus and feeder insulation pre-alarm and fault alarm, AC intrusion and feeder detection, DC current transformer and feeder detection, switch tripping and status detection, feeder current detection, and balanced bridge and fault detection. It also provides bus voltage deviation compensation, with device fault, comprehensive fault, insulation alarm, insulation pre-alarm, AC intrusion, and DC current transformer fault contact outputs. Backend communication supports both CAN and RS485, with an IRIG-B time synchronization interface.
