JY2000-AL IMD Insulation Monitoring Device can monitor the insulation resistance value of the positive and negative poles of the DC floating system to ground from 1kΩ to 10MΩ, and can also detect the DC voltage value from 100V to 2000V. 3 Functions are optional: without communication, alarm dry contact output; with communication only; with communication alarm dry contact output.
Insulation resistance monitoring can only be realized when the DC voltage is between 100V and 2000V. When the DC voltage is less than 100V, or the insulation monitoring is not enabled, the insulation resistance read is 65535 (invalid value). When the measured value is greater than 10MΩ, the value received by the communication is 60000 (infinity).
