Event Output (Open Collector Output) Connection

Handling Precautions

• Do not short-circuit the positive (+) terminal of the external power supply

to terminals (5) to (8), (17) to (20), (10), (11), (22), (23), (27), (28), (31),
and (32) on the

DCP552

. Doing so causes the open collector outputs to

malfunction. (There is no short-circuit preventing circuit inside.)

• When connecting a semiconductor load such as a programmable

controller (sequencer), select a module in which the current directions
match.
Use one made inoperative by the leakage current produced when the
digital outputs are shut off.
