BIM-CH2 Dual Channel Insulation Monitoring Device for EV Charging Station

Information

Blue Jay BIM-CH2 is a dedicated dual channel insulation monitoring device (IMD) engineered for two independent 100–1000V unearthed DC IT circuits, perfectly matching dual-gun DC EV charging piles. Adopting stable bridge circuit measurement technology, this compact DIN-rail unit monitors two charging loops separately at the same time without mutual interference, replacing two single-channel monitors to cut hardware cost and simplify internal wiring of dual-gun chargers. It supports independent alarm threshold setting (1kΩ–10MΩ) for each channel and complies with IEC 61557 industrial standards. It continuously tracks positive/negative pole ground insulation resistance of both charging guns, triggers independent relay alarm outputs once insulation degradation occurs, and supports manual self-test & wiring fault detection. Equipped with RS485 Modbus-RTU communication, it uploads real-time insulation data to charger controllers for remote monitoring. Beyond dual-gun charging stations, it also fits energy storage, substation DC panels and dual-loop DC distribution systems, preventing ground short-circuit risks and guaranteeing safe charging operation.
