The insulation monitor RN 5897/311 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 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.
