BENDER IREH150P INSULATION MONITORING DEVICE

The A-ISOMETER®s IREH150 and IREH150P are used for off-line monitoring of earthed and unearthed single and three phase AC networks up to 660 V and DC networks up to 500 V. The connecting leads of idle consumers, e.g. motors, are monitored continuously.

The offline monitor detects insulation faults. Two output contacts can be used for signalling or motor restart interlocking.

 The devices require a supply voltage of AV ... Hz 230 V. Other values  on request.

To obtain that monitoring is performed only in idle condition, the control voltage of the contactor coil is measured at the contactor for the respective load.

 If voltage is present, the monitoring will be suppressed. Only in case of no voltage, the consumer including the wiring will be monitored.

The control voltage of the contractor coil can be AV 24...380 V or DC 24...500 V.
