HANDLING PRECAUTIONS
8 17 18 19 20 9
• 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 DCP551. 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.
