Engineering Insight

Compact and Versatile Expansion
This module adds 4 inputs and 4 high-current relay outputs in a slim 2-unit package, perfect for small-scale automation expansions using LOGO! 8.

Flexible Power & Signal Operation
Works reliably across a wide supply voltage range (10.8–28.8 V), ideal for mixed-system environments.

Fast and Efficient Response
Low input delays and powerful relay outputs (up to 5 A switching) allow for prompt and heavy-duty actuation—great for real-time control tasks.

Simple and Efficient Installation
Easy snap-on DIN-rail mounting and standard LOGO! integration make setup and deployment quick—even in constrained panel spaces.
