Product Overview

The CP1W-20EDT1 extends controller I/O without requiring major panel redesign, making it practical for machine upgrades and standard platform variants. Its balanced point count supports additional sensing and output control for conveyors, actuators, and station logic. It is commonly used by OEMs to keep core PLC programs stable while scaling machine features through modular expansion. This improves maintainability and gives engineering teams a low-risk path to add functionality over time.

FAQ for CP1W-20EDT1

What's the difference between NPN and PNP output?
NPN (20EDT): switches negative/0V side (sinking). PNP (20EDT1): switches positive side (sourcing). Choose based on load wiring and regional standards (NPN common in Asia, PNP in Europe).
Can I mix NPN and PNP expansion units?
Yes, you can mix NPN and PNP output units in same system. Each unit is independent. Choose output type based on individual load requirements.
What loads can PNP output switch?
0.3A per point: solenoid valves, indicator lamps, small relays, pilot lights. For higher current, use output to control external relay/contactor.
How do I wire PNP output?
Load + to 24V+, load - to output terminal. Output switches 24V+ to load when ON. Common terminal connects to 24V+.
