SIMATIC S7-1200 Digital Output SM 1222 6ES72221BF320XB0

The SIMATIC S7‑1200 SM 1222 (6ES72221BF320XB0) is a high-performance digital output expansion designed to elevate your PLC control system with reliable, fast-response switching capabilities. Offering 16 transistor outputs operating at 24 V DC, this module is capable of switching diverse loads—including valves, relays, LED indicators, and small motors—while each channel delivers a current capacity of up to 0.5 A.

Built to industrial standards, the SM 1222 features short-circuit and overload protection for every output channel, safeguarding your installation from electrical faults and reducing machine downtime. It mounts directly onto the SIMATIC S7‑1200 DIN-rail, ensuring synchronized and efficient data exchange with the CPU and other networked modules via PROFINET.

With fast switching speeds and cycle consistency, this module supports precise control applications, such as sequential operations, signal repeats, or time-critical interlocks. It integrates seamlessly within the TIA Portal engineering environment, enabling rapid configuration, live diagnostics, and clear status indication through internal LEDs, simplifying maintenance and troubleshooting.

Offered by Scalar Automation in Kenya, the SM 1222 is ideal for machine builders, OEMs, and automation engineers who seek dependable, compact, and scalable digital output expansion for modern industrial systems.
