4-11 Connecting Time Event Output (open-collector)

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 (55) 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 (49) to (53) on the DCP301. Doing so will cause faulty open-collector output.

(The DCP301 does not contain a short-circuit prevention circuit.)

When connecting to a semiconductor load such as a programmable controller (sequencer), select a module whose current directions are matching.

Use a module that does not operate by leakage current when the open-collec- tor output of the DCP301 is OFF.
