Engineering Insight

High-Density, Compact Design
At a mere 15 mm width and 35 g weight, this module delivers eight digital inputs in a minimal footprint—perfect for tight ET 200S racks.

Reliable Signal Handling
With support for 2-wire sensors and broad input voltage range (–30 V to +30 V), it’s robust in noisy industrial environments.

System Integration
No user-accessible parameters simplifies setup. Integrated status LEDs provide clear channel feedback. Isochronous mode supports synchronized applications.

Spare Part Only
Since being phased out in 2023, ensure ongoing installations incorporate sufficient reserves or consider replacement planning.
