Siemens SIMATIC S7-1200 SM 1223 Módulo de E/S digitales, 8 DI 24V DC, 8 DO relé, 6ES7223-5PH50-0XB0

The Siemens SIMATIC S7-1200 SM 1223 is a compact digital input/output module designed for the SIMATIC S7-1200 controller system. It combines 8 digital inputs (24 V DC) and 8 digital outputs (relay type) in a single unit, providing a space-saving solution for industrial automation applications. The module is DIN rail mountable and features electrical isolation between channels and the backplane bus for reliable operation in harsh environments.

Advantages

Integrated 8 DI and 8 DO in one module reduces wiring and cabinet space. Relay outputs allow switching of both DC and AC loads up to 2 A per channel. Configurable input type (sink/source) offers flexibility. Status LEDs provide quick diagnostics. Firmware updateable via the CPU for future enhancements.

Suitable for

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