The SM 1222 (6ES72221HH32‑0XB0) is a robust digital output expansion unit for Siemens S7‑1200 PLCs, equipped with 16 transistor outputs designed to handle 24 V DC loads up to 2 A per channel. Ideal for switching medium-duty devices such as solenoid valves, motors, heaters, and indicator systems, it offers reliable and efficient output performance.
Each channel comes with built‑in short-circuit and overload protection, eliminating the need for external safeguards and enhancing system safety. The module’s slim, snap-on DIN-rail housing ensures space-saving installation, while its seamless backplane integration with the S7‑1200 CPU enables precise, synchronized operation through PROFINET.
Easy configuration and monitoring are facilitated through TIA Portal, allowing clear diagnostics via onboard LEDs and system alerts. Designed for industrial-grade durability, this output module stands up to harsh environments, temperature fluctuations, and heavy-duty applications.
Available through Scalar Automation in Kenya, the SM 1222 (HH32) caters to engineers and machine builders looking for powerful, compact, and safe digital control expansion in modern automation projects.
