It accepts a wide supply range from 24 V DC up to 230 V AC (47–63 Hz), making it a direct-fit spare for S7-22X CPU racks that need isolated switching of valves, contactors, or signal lamps across mixed-voltage field wiring. The relays provide potential separation between channels in groups of 4, with a mechanical life of 10 million cycles and 100,000 cycles at rated load voltage. No short-circuit protection is built in — the external circuit must handle that. ## Current lifecycle — still orderable for legacy S7-200 installs This module carries a current lifecycle status, meaning it remains available through distribution channels for supporting the installed base of S7-200 systems. It is listed as a spare part specifically for S7-22X CPUs — not for later S7-200 SMART or S7-1200 families. The 62 mm depth, 45 mm width, and 80 mm height match the standard S7-200 expansion module footprint. Plug-in I/O terminals simplify field replacement without re-terminating the entire cabinet. ## Load ratings and wiring constraints Each output handles 2 A resistive or inductive load, with a maximum lamp load of 200 W on AC or 30 W on DC. The total current per common conductor group is capped at 8 A, and the module draws 72 mA from the load voltage supply (9 mA per switched output) plus 40 mA from the backplane bus. Unshielded cable runs up to 150 m are permitted; shielded runs extend to 500 m. The permissible voltage range for the relay contacts is 5–250 V AC or 5–30 V DC — useful when switching mixed loads on the same output group.","metaTitle":"Siemens 6ES7222-1HF22-0XA0 S7-200 EM 222, 8 Relay Outputs","metaDescription":"Siemens 6ES7222-1HF22-0XA0 S7-200 EM 222 digital output module with 8 relay outputs rated 2A. 24V DC to 230V AC.
