Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The CJ1W-MD231 is an Omron CJ-series mixed I/O module combining 16 sinking DC inputs and 16 transistor (sinking) DC outputs in one compact unit. It connects to CJ/NJ CPU units via Fujitsu/OTAX 24-pin connectors. It enables both input sensing and output switching within a single module, simplifying installation and conserving rack space. The unit suits standard industrial automation tasks including discrete I/O expansion in manufacturing lines and machine control. CJ1W-MD231 integrates seamlessly into Omron CJ1 systems for mid-range control architectures.
Best Suited For
- Discrete I/O expansion on CJ1/NJ platforms
- Applications requiring both inputs and outputs in one module
- Compact rack installations with limited space
