The insulation monitor RN 5897/321 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 of 1st response value (Pre-alarm): 20 kΩ … 500 kΩ
Setting range of 2nd response value (alarm): 1 kΩ … 100 kΩ
1 changeover contacts each for insulation failures-Pre-alarm and -alarm
Energized or de-energized on trip can be selected for indicator relay
With multicolour status LED to indicate the state of operation.
Automatic and manual device self-test
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
