Le Siemens 6ES7222-1AD30-0XB0 est un compact SIMATIC S7-1200 SB 1222 digital output signal board that expands an S7‑1200 CPU with 4 high-speed 5 V DC outputs without increasing the overall footprint of the controller. It plugs directly into the front receptacle of the CPU, making installation simple and maintaining the same mounting dimensions as the standard S7‑1200. Designed with MOSFET solid-state outputs, it supports current-sinking/sourcing loads and is ideal for applications requiring fast switching up to 200 kHz, such as pulse outputs, counting, and small motion or positioning tasks.
The module operates at a 5 V DC output level, avec un rated output current of 0.1 A per channel and a maximum permissible current of 0.11 UN, suitable for driving low-power actuators, capteurs, and interface circuits. It draws a typical 50 mA from the S7‑1200 backplane bus, so no additional external supply is required beyond the CPU power. Avec diagnostic functions and status LEDs for each output, the SB 1222 supports fast fault localization and easy commissioning in the TIA Portal environment. The small housing (approx. 38 × 62 × 21 mm, about 40 g, IP20) is designed for cabinet mounting as part of the overall S7‑1200 system and operates in standard industrial conditions from 0 à 55 °C with up to 95% non‑condensing humidity.
