Parallel DO (output signal) connection
The DO load current can be doubled by connecting two DO points in
parallel and turning them on and off simultaneously in sequence, as
shown in the figure below. The maximum load current per DO point is
200 mA. Connecting two DO points in parallel and turning them on at
the same time produces a current of 400 mA. Note that, however, when
two DO points are connected in parallel, the leakage current also doubles
when they are off (max. 40 mA).
