How do you monitor the output current of the ET 200SP Power Supply in the user program of the CPU?

  • Entry
  • Associated product(s)
The ET 200 SP PS is a primary-clocked power supply for connection to a 1-phase AC power supply.

At the output of the device is an electronically controlled direct voltage that can be set via a potentiometer. The output of the device is potential-free, no-load proof and short-circuit proof.
The ET 200SP PS has a current monitoring terminal to which you can connect an analog input module of the ET 200SP, for example. In this way the output current of the ET 200 SP PS can be captured in a CPU.

Fig. 1 and Table 1 show the hardware configuration.
