Honeywell DCP552 Mark II, User Manual

Page: 37 / 247

4 - 7 Control Output Connection
●
Current output (5G, 5S)
●
Voltage output (6D)
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 the load. Enter the
value in the setup data. A normal SSR voltage has been set at the factory
before shipment.
●
Open collector output (8D)
Handling Precautions
• Do not short-circuit the positive (+) terminal of the external power supply
to terminal (43) 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.

WARNING
Be sure to turn off the power supply when you are installing or removing the
controller.
Failure to do so may cause electric shock or fire.
