Product Overview
BIM-M1000 monitors insulation resistance in unearthed power systems and reports faults through indicators and relays. It is a monitoring instrument, not a disconnect or fault-clearing device.
Key Features
- Ungrounded AC/DC IT-system monitoring
- Two configurable response values
- Relay and LED alarm outputs
- DIN-rail installation
- RS485 Modbus RTU

Applications
Illustrative panel environments; confirm equipment fit and circuit requirements for the selected model.
Battery DC IT Networks
Insulation-fault monitoring when the system is ungrounded.
DC Power Distribution
Remote alarms to a panel controller or monitoring system.
Information to Confirm for Selection
- Grounding/IT topology and maximum bus voltage
- Required alarm thresholds and response time
- System capacitance and parallel monitor coordination
- Supply, relay and communication integration
FAQ
Can it be used on a 1500V DC system?
No. The selected BIM-M1000 source lists a maximum of 1000V AC/DC.
Does it open the battery circuit after an alarm?
It outputs alarms; external control and switching require separate design.
