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.
