Product Description

The BIM-CH1 monitors the insulation resistance of DC systems (IT systems) devices up to DC 0- 1000V. BIM-CH1 has insulation monitoring start and stop functions. After insulation monitoring is turned on, it can real time monitor the insulation resistance of the positive and negative poles to the ground. The monitoring results are not affected by DC voltage fluctuations and the symmetry of the insulation resistance of the positive and negative poles.

BIM-CH1 is equipped with RS485 /Modbus communication, which can remotely monitor the system status. BIM-CH1 uses two working principles for monitoring: unbalanced bridge method and balanced bridge method, allowing continuous monitoring of voltage and resistance values. Optional current sensors or temperature sensors can be configured for current and temperature measurements.
