Siemens 6ES7222-1HF22-0XA0 is an 8-channel digital output module (EM 222) for SIMATIC S7-200 controllers, designed exclusively for S7-22X CPUs. It provides eight relay-output contacts capable of switching up to 2 A per channel, enabling control of actuators, solenoids, lamps, and similar field devices from the S7-22X family. Used as part of a SIMATIC S7-200 system, the EM 222 expands the controller's digital output capacity.
