BIM-M1000 is designed to monitor the insulation resistance of unearthed AC/DC systems (IT systems) up to 1000Vac/DC. The device generates ±15V pulsating measuring voltage to injection on the IT system. When the value falls below the preset response values, the alarm LEDs light up. The device support two separately adjustable response values allow 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.
