Siemens 6ES7222-1HF32-0XB0 Digital Input Module

Siemens 6ES7222-1HF32-0XB0 is an eight‑channel digital output module (SM 1222) for the SIMATIC S7-1200 family, delivering eight 24V DC relay outputs that can switch loads up to 2 A per channel. Designed as an expansion card for the S7‑1200 system, it mounts on the backplane and uses a front connector, with an IP20-rated front enclosure for protection. The module’s footprint is 45 mm wide by 100 mm high, making it a compact addition to the rack of I/O modules. Each output switches a 24 V DC load, with a relay coil current specification up to 11 mA per relay, enabling reliable control of actuators, solenoids, lights, or other 24 V devices under PLC supervision. This device is part of Siemens’ SIMATIC S7-1200 signal module lineup, suitable for expanding digital output capability in compact automation applications.
