IsoTxA-Mk2
Insulation and Loop Resistance
The IsoTxA-Mk2 is a stand-alone measurement and monitoring device for insulation and loop resistance. A dedicated copper pair is used as a measurement loop in the monitored cable. This loop is being measured continuously by the IsoTxA-Mk2. The thresholds for the insulation and loop resistance values are easily programmable with the built-in keys. The integrated display shows the measurement values andsettings.
Dry output relay contacts are built-in for remote alarming. Additionally the IsoTxA-Mk2 can be equipped with plug-in interface modules for LANCIER Tx-Bus, CAN-Bus or telecontrol systems via Modbus by RS485 interface.
