3.3 INSULATION MONITORING IR155-3204
The BMS MASTER is prepared for the cooperation with the Bender insulation monitor
IR155-3204.
Only one insulation monitoring device may be used in each interconnected
system. When insulation or voltage test are to be carried out, the device shall be
isolated from the system for the test period.
IR155-3204 Measurement Output Highside
 Measurement of insulation resistance with modified DCP method
o Response time <2s for first estimated insulation resistance
o Response time <20s for measured insulation resistance
 Detection of ground faults and lost ground line.
 Short protected outputs for:
o Fault detection (high side output)
o Measurement Value (PWM 5…95%) & Status (f=10..50Hz) at high and
inverted low side output
