This is the spare part designated for S7-22X CPUs only — it will not fit later S7-200 SMART or S7-1200 families. ## Output ratings and voltage flexibility Each relay output switches 10 A resistive and up to 3 A inductive on AC or 2 A on DC. The voltage range spans 12-250 V AC and 12-30 V DC (-), so it handles mixed-voltage loads on the same module — 24 V DC pilot valves alongside 120 V AC contactors, for example. Current derating is significant above 40 °C: the module delivers 40 A total at 40 °C but only 20 A total at 55 °C. With 4 outputs at 10 A each, you hit the 40 A ceiling with all channels fully loaded at lower ambient; above 40 °C you must budget the derating. Plug-in I/O terminals simplify replacement — the module swaps without re-terminating field wiring, a real time-saver when you're holding a spare in the cabinet. ## Lifecycle and sourcing — active spare, not obsolete Siemens lists this module as current production. It is a designated spare part for the S7-200 platform, which means it remains available for installed-base support even as the platform itself ages. No official successor exists on record — this is the direct replacement for earlier EM 222 variants. For a maintenance-spares purchaser, this is the one to keep in the cabinet for any S7-200 relay-output slot. The 30 million mechanical cycles rating gives solid MTBF confidence for intermittent-duty loads like valve positioners or signal lamps.","metaTitle":"Siemens 6ES7222-1HD22-0XA0 Digital Output Module","metaDescription":"Siemens 6ES7222-1HD22-0XA0 SIMATIC S7-200 EM 222 digital output module, 4 relay outputs, 10 A, 24V DC / 24-230V AC.
