SIEMENS - SIMATIC S7-1200 - Digital Output Signal Boards

The Siemens SIMATIC S7-1200 SB1222 Digital Output Signal Board expands compatible SIMATIC S7-1200 CPUs with four additional 24 V DC transistor digital outputs while maintaining the compact footprint of the controller. The board installs directly into the dedicated Signal Board slot on the front of the CPU, providing additional output channels without increasing the overall PLC width or occupying an expansion module position.

Designed for machine automation and industrial control applications, the SB1222 enables reliable switching of solenoid valves, relays, contactors, indicator lamps and other 24 V DC loads. Its transistor outputs provide fast electronic switching with integrated short-circuit protection, while seamless integration into Siemens STEP 7 using TIA Portal simplifies configuration, diagnostics and maintenance.
