Dold RN5897.12/61 DC12-24V 15K-100K, Insulation monitor, sku: 0070034

The insulation monitor RN 5897 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 even with large leakage capacity to earth (PE). The adjustment of the setting values is simple and user friendly done on 2 rotary switches on the front of the device. Via display and LEDs the measured value, device parameters and device status are indicated easy to read. With a sealable transparent cover the device is protectet against manipulation.

• Insulation monitoring according to IEC/EN 61557-8
• 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): 15 kΩ … 100 kΩ
• 2 changeover contacts für insulation failures-Pre-Alarm and -Alarm
• Energized or de-energized on trip can be selected for indicator relay
• Display for indication of measured value, device parameters and device status
• Setting the maximum leakage capacitance to shorten the response time
• Automatic and manual device self-test
• Alarm storage selectable
• Protection against manipulation by sealable transparent cover
• External control input for combined Test-/Reset-button
• 3 wide voltage input for auxiliary voltage
• Width 52.5 mm
