Siemens 6ES7 222-1BF22-0XA0 Programmable Logic Controller Module

Siemens 6ES7222-1BF22-0XA0 is the EM 222 Digital Output module for the SIMATIC S7-200 family, designed to plug into an S7-22x CPU backplane. It provides eight 24 V DC outputs (DO), capable of switching up to 0.75 A per channel, with optical isolation between the backplane and the loads it drives, making it suitable for directly powering relays, solenoids, and other 24 V devices. The EM 222 draws about 2 W and requires a 5 V DC logic supply plus a 24 V DC load supply, with the logic rail typically drawing up to 50 mA. Its compact footprint measures 46 mm wide by 80 mm high by 62 mm deep and it weighs around 150 g, enabling easy integration in compact automation panels to expand the output capability of S7-200 configurations. The part number 6ES7222-1BF22-0XA0 specifically denotes EM 222 DO 8 x 24 V DC, 0.75 A per channel, intended for S7-22x CPUs.
