Function
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.
