Siemens SIMATIC S7-1200 SM 1223 Módulo de E/S digital, 8 DI 24 V DC, 8 DO relé, 6ES7223-5BH50-0XB0

The Siemens SIMATIC S7-1200 SM 1223 is a compact digital I/O signal module designed for the SIMATIC S7-1200 automation system. It combines 8 digital inputs (24 V DC, sink/source configurable) and 8 digital outputs (relay, NO contact, 2 A per channel) in a single module, providing flexible and reliable control for industrial applications. The module is DIN rail mountable and features screw terminal connections for easy wiring.

Advantages

This module offers a space-saving solution by integrating both inputs and outputs, reducing the number of modules needed. The relay outputs allow switching of higher voltages (up to 250 V AC) and currents, making it suitable for direct control of actuators, motors, and other industrial loads. The configurable inputs support both sink and source wiring, providing flexibility in sensor integration.

Suitable for

• Industrial automation and control systems
• Machine building and manufacturing
• Process control and monitoring
• Building automation
