Optional time event outputs T1 to T5 (open-collector outputs) can be added on. Time event
outputs are connected on the add-on terminal base.
Handling Precautions
• Be sure to connect terminal to the + terminal of the external
power supply.
Otherwise, open-collector output will not function.
• Do not short-circuit the + terminal of the external power supply
and terminals to on the DCP31. Doing so will cause faulty
open-collector output.
(The DCP31 does not contain a short-circuit prevention circuit.)
• When connecting to a semiconductor load such as a program-
mable controller (sequencer), select a module whose current
directions are matching.
Use a module that does not operate by leakage current when the
open-collector output of the DCP31 is OFF.
