Voltage output
HANDLING PRECAUTIONS
The voltage output is a constant current circuit inside. The SSR used is set to an
optimum voltage to meet the requirements of hte load. Enter the value in the
setup data. A normal SSR voltage has been set at the factory before shipment.

Open collector output
HANDLING PRECAUTIONS
• Do not short-circuit the positive (+) terminal of the external power supply to
terminal (43) 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.
