DC link monitor

A signal proportional to the DC link input current can be picked up at the DC link monitor (X9:2). The DC link monitor is designed as a 4 – 20 mA current interface.

The DC link monitor corresponds to the current flowing from the DC link into the switched-mode power supply module via terminal X4.

The characteristic curve of the DC link monitor is shown in the following diagram:
