* Function of insulation resistance monitoring, fault warning and alarm for the monitored IT system.
* Multiple fault indication function, such as relay alarm output and LED alarm output.
* Advanced field bus communication technology, and it can communicate with the host computer management terminal and monitor the operation status of the IT system in real time.
* Fault event recording function. It can record the time and type of failure to provide convenience for operators to analyze the operation status of the system and eliminate faults in time.
* Applicable for insulation monitoring of AC, DC and AC / DC hybrid IT systems.
* Self checking function. realize the fault self-inspection of instrument hardware circuit.
* Broken line monitoring function. Monitor the connection condition of the PE/KE function grounding wire.
* The free option of manual reset/automatic reset.
* Wide range of measurement, Allowable leakage capacitance of the system is large.
