SIEMENS - SIMATIC S7-1200 - Digital Output Modules

The Siemens SIMATIC S7-1200 SM 1222 Digital Output Modules expand the digital output capability of SIMATIC S7-1200 PLC systems, providing reliable switching of industrial loads including contactors, relays, solenoids, indicator lamps, valves and other field devices.

The SM1222 family is available with transistor, relay and changeover relay output technologies, allowing the module to be selected according to the application's switching speed, load characteristics and voltage requirements. Modules are available with 8 or 16 digital outputs, integrate directly with compatible SIMATIC S7-1200 CPUs via the backplane bus, and are engineered using Siemens STEP 7 within TIA Portal.

Integrated diagnostics, firmware update support and reconfiguration during RUN simplify commissioning and maintenance for industrial automation systems.
