The SM 1222 (6ES7222‑1BH32‑1XB0) is a high-performance digital output expansion module tailored for the SIMATIC S7‑1200 PLC platform. It offers 16 transistor outputs that operate at 24 V DC, each capable of driving loads up to 0.5 A, making it ideal for switching signals, LEDs, relays, and small actuators in automation systems.
Designed to save space and simplify installation, the module snaps directly onto the S7‑1200 DIN rail and communicates reliably with the CPU via the backplane bus. Engineers can easily configure it using TIA Portal, where output types, timing sequences, and diagnostic settings are set up with intuitive tools. Bright LEDs on the front panel offer real-time status for each output channel, helping with fast troubleshooting.
Robust protection features—such as overload and short-circuit interruption—are built in, minimizing the need for extra hardware and boosting system reliability. Housed in an industrial-grade IP20 enclosure, the SM 1222 (1BH32 model) is engineered to endure factory environments and maintain consistent performance.
Available through Scalar Automation in Kenya, this digital output module is ideal for machine builders, OEMs, and system integrators who require reliable, compact, and scalable I/O expansion for modern automation projects.
