The insulation monitor RN 5897/100 of the VARIMETER IMD family is a solution for optimal insulation monitoring of modern IT systems. The device can be used in the most flexible way for AC, DC and AC/DC systems. Mains areas of applications are non-earthed DC charging stations for electric vehicles with mains voltages up to DC 1000 V, that need an extended temperature range. The setting of the parameters and the switching values is done via Modbus. All measured values, device statuses and parameters can also be read out via Modbus. All functions of the device can also be operated via Modbus. The operating status is indicated user friendly via a multicolour LED. With a sealable transparent cover the device is protectet against manipulation.

Features

2 separate adjustable response thresholds (using e.g. for pre-alarm and Alarm)
Setting range pre-alarm: 1 kΩ … 500 kΩ
Setting range alarm: 1 kΩ … 500 kΩ
2 parameterizable changeover contacts (for insulation fault pre-alarm, insulation fault-alarm, insulation fault-alarm on DC+/DC- or device fault) each galvanic separated
Energized or de-energized on trip can be selected for indicator relay
With multicolour status LED to indicate the state of operation.
Manual device self-test (automatic device self-test can be activated)
Alarm storage selectable
Protection against manipulation by sealable transparent cover
External control input for combined test- / reset-button with additional Stop of the measuring function
2 wide voltage input for auxiliary voltage
Width 52.5 mm
