Siemens 6ES7 222-1EF00-0XA0 Digital Output Module (EM222) for the SIMATIC S7-200 family expands a controller with eight optically isolated digital outputs that switch AC loads in the 24–264 VAC range, rated up to 1 A per channel. Designed for S7-21x CPUs, this eight-output module is ideal for energizing relays, contactors, valves, lighting, and other AC devices under PLC control, while maintaining isolation between the CPU and controlled loads. It mounts in the S7-200 backplane, enabling a compact, modular solution for small to mid-sized automation projects.
