IK 9139

The IK 9138 / IK 9139 varimeter is a modular current monitoring system that consists of a reporting unit IK 9138 and 1 to 30 current monitors IK 9139. This means that the current consumption levels of different electricity consumers can be monitored. If one of the currents that is being monitored drops below the fixed current setting, the LEDs on the relevant current monitor and the reporting unit go on. The central reporting relay in the reporting unit is actuated. The reporting unit needs to be connected to an auxiliary voltage supply. The current monitors obtain their supply voltage from the reporting unit via a plug-in bus line.
