BIM-4MS Cost-Effective Insulation Monitoring Device for Floating DC IT Systems

Information

Blue Jay BIM-4MS is an economical insulation monitoring device (IMD) specially designed for floating / unearthed DC IT systems with 100–1000V DC voltage. It delivers reliable continuous insulation monitoring at a competitive cost without redundant complex functions, perfectly matching standard single-loop floating DC power systems. It supports independent start-stop monitoring control and real-time synchronous measurement of positive and negative pole insulation resistance to ground, adapting automatically to system leakage capacitance up to 5μF. This cost-saving floating DC IMD features adjustable insulation alarm thresholds ranging from 1kΩ to 10MΩ, user-selectable NO/NC relay contacts, two configurable alarm modes, plus manual and automatic reset options. Built-in RS485 Modbus RTU communication enables remote real-time data upload and system centralized management. It detects early insulation degradation to prevent ground short-circuit risks, widely applicable to general energy storage, single-gun EV chargers, substation floating DC panels and standard industrial floating DC distribution systems.
