and actions of any device could influence each other, i.e. breakdown of the
entire auto-control system. Therefore, we suggest you wire a protection
circuit at the power supply input terminal. See the figure below.

I/O Point Wiring
There are 2 types of DC inputs, SINK and SOURCE. (Below is an example.
For detailed wiring configuration, please refer to specifications of each
module.)
