Switching Electronic Loads

Switching electronic loads
When switching electronic loads, increased inrush currents that significantly
exceed the rated current can be caused by internal capacities in the electronic
loads. This can lead to passivation of the F I/O module with the "Overload"
diagnostic message. You can remedy this by limiting the inrush current, e.g., by
placing an additional series resistor between the digital power output and the
electronic load.
You can switch electronic loads (e.g., electronically controlled door locking
device) using the F I/O module.

Connecting a Load between Ox+ and Ox-

Figure 5: Connecting One Load to Each Digital Power Output
You can connect a load between the digital power outputs Ox+ and Ox-. If you
want to deactivate open load detection for the load, set the Open load detection
parameter to "not active". Otherwise, set the Open load detection parameter to
"active" so that the F I/O module performs the open load detection task once per
minute.
For more information about configuring the F I/O module, read section
"Parameterization of the F I/O module with the WAGO Parameterization Tool".
