Product Description
This digital I/O expansion module is designed for Siemens SIMATIC S7-200 systems, providing eight 24 V DC digital inputs and eight 24 V DC digital outputs in a compact EM223 form factor. It supports sink/source input configurations and 0.75 A per output sourcing capability, suitable for interfacing sensors and actuators in small to mid-size control applications. Typical use includes extending I/O capacity on S7-22x CPUs with reliable isolation and robust terminal connectivity. The module is intended for industrial environments requiring deterministic digital control, with support for shielded cable runs up to 500 m where noise immunity is critical. The unit’s low power loss and modest input current draw help maintain panel thermal budgets. It connects via plug-in I/O terminals for serviceability and accepts standard 2-wire sensors. Ensure group current limits are observed and that conductor lengths meet installation practices for shielded and unshielded runs.
