Omron CP1W-40EDT1 Digital Expansion Unit – CP1W Series I/O Expansion Module
When a production line loses its I/O expansion module, the consequences are immediate and severe: PLCs lose contact with field devices, conveyor systems halt, robotic arms freeze mid-cycle, and entire manufacturing cells go dark. Downtime in modern industrial environments can cost thousands of dollars per minute — and sourcing a certified replacement quickly becomes the single most critical task on the floor. The Omron CP1W-40EDT1 is precisely the component that restores control, restores output, and gets your line running again.
Within the CP1W expansion series, the CP1W-40EDT1 occupies a high-density, NPN transistor output position — offering 24 digital inputs and 16 NPN transistor outputs in a single compact unit. Designed to integrate seamlessly with Omron’s CP1H and CP1L PLC families, this module is a globally recognized standard in discrete manufacturing, packaging automation, and machine tool control. Its transistor output architecture makes it the preferred choice for high-speed, high-cycle applications where relay outputs would degrade prematurely.

Frequently Asked Questions
- Q: Is the CP1W-40EDT1 compatible with the CP1E series?
- A: No. The CP1W expansion bus is designed for CP1H and CP1L series PLCs. The CP1E series uses a different expansion architecture (CP1E expansion units). Please verify your CPU model before ordering.
- Q: What is the difference between CP1W-40EDT and CP1W-40EDT1?
- A: The CP1W-40EDT features PNP (source type) transistor outputs, while the CP1W-40EDT1 features NPN (sink type) transistor outputs. Selection depends on your field device wiring convention — NPN is more common in Asian markets, PNP in European applications.
- Q: How many CP1W-40EDT1 units can I connect to one CPU?
- A: The maximum number of expansion units depends on the specific CP1H or CP1L CPU model. Refer to the Omron CP1H/CP1L hardware manual for the expansion unit limit applicable to your CPU variant.
