I/O Module with Eight Inputs and Outputs

The Festo CPX-8DE-8DA is a digital I/O module designed for 24V DC automation systems. It provides eight digital inputs and eight digital outputs in a single unit. The module integrates into CPX terminal strips for centralized control tasks. It is intended for industrial electricians and panel builders wiring sensor and actuator signals.

Suited for CPX System Expansion Only

This module fits buyers expanding an existing Festo CPX valve terminal or remote I/O station. It is not suitable for stand-alone operation without a CPX bus node or controller. Users needing analog signal processing or higher channel counts should look at alternative modules. Installers without CPX platform experience will require additional system components.

24V DC Operating Voltage

The module operates exclusively on a 24V DC supply voltage. This voltage level determines compatibility with the CPX system power distribution and connected field devices. Verify that the control cabinet power supply delivers 24V DC before installation. The part number 526257 confirms the exact variant for ordering.

Questions about this item

How does the 24 V rating translate when the module is installed in a CPX terminal?

The module operates directly from the 24 V DC system supply distributed through the CPX backplane, so no separate power wiring is needed for the I/O points.

What connection standard does the CPX-8DE-8DA use on the backplane and what does it limit?

It uses the proprietary CPX backplane bus, which fixes the address space to eight digital inputs and eight digital outputs per module.

What does the module need to mount in a control cabinet?

It mounts on a standard DIN rail inside the CPX housing and requires one free slot in the terminal row.
