The insulation monitor RN 5897/240 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. The setting of the parameters and the switching values is done by simple and operator friendly rotational switches on front of the device. The operating status is indicated user friendly via a multicolour LED. With a sealable transparent cover the device is protectet against manipulation.
Features
- Setting range of 2nd response value (alarm): 1 kΩ … 500 kΩ
- 1 changeover contacts each for insulation failures alarm and device failures
- 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
- With semiconductor output to indicate the insulation resistance (PWM)
- 3 wide voltage input for auxiliary voltage
- Width 52.5 mm
