RS485 insulation monitor BIM-M1000

AC/DCDIN railModbus RTU

The BIM-M1000 is designed to monitor the insulation resistance of unearthed AC, AC/DC, and DC systems (IT systems) up to AC/DC 1000V. The device generates ±15V pulsating measuring voltage, which is injected into the IT system to be monitored via terminals L1/L2 and Earth. When the value falls below the preset response values, the alarm LEDs light up. The device supports two separately adjustable response values, allowing a distinction to be made between “pre-alarm” and “alarm”. BIM-M1000 complies with IEC 61557-1:2018 and IEC 61557-8:2018 standards and is suitable for AC/DC IT systems, battery energy storage, electric vehicles, DC charging stations, and other scenarios. It also supports RS485 and CAN bus communication, facilitating integration into remote monitoring systems. - Insulation monitoring of unearthed AC, AC/DC, and DC systems - Measurement of DC system voltages to earth (L+/PE and L-/PE) - Measurement of AC system voltages to earth (System to PE) - Two separately configurable response values - Alarm signaling via LEDs and alarm relays - Complies with standards IEC 61557-1/ IEC 61557-8 - Overvoltage alarm function - Measuring the system leakage capacitance Applications: - AC and DC IT power distribution systems - Industrial power and automation - Marine electrical power distribution network systems - Battery packs and energy storage systems - Electric vehicles and transportation - Renewable energy power generation systems - DC charging stations for electric vehicles Specifications: - Power supply: 9~30Vdc, power consumption ≤ 2W - Frequency range: 40~65Hz - Nominal system voltage: 3(N)AC, AC/DC 0…1000 V - Insulation resistance: 0~50MΩ - Injection measuring voltage: ±15V - Injection measuring current: 100mA - Max. withstand voltage: 12Vdc - Pre-alarm threshold: Default 1000Ω, 0-5000Ω adjustable - Alarm threshold: Default 500Ω, 0-5000Ω adjustable - Overvoltage detection: 0-1000V - RS485 interface: Modbus RTU protocol - Canbus interface: Custom protocol - Working temperature: – 40°C ~85°C, humidity: 5~95%RH - Storage temperature: – 40°C ~85°C, humidity: 5~95%RH - Standards: IEC 61557-1:2018 and IEC 61557-8:2018 - Installation method: Standard 35mm Din-rail mounting - Dimension: W*H*D: 108*110*66mm
