The inputs accept 24 V AC/DC or 230 V AC, so they work straight off the line voltage or a 24 VDC sensor bus — no separate input power supply needed for the field side. Each relay output switches up to 0.75 A resistive or inductive load, which covers most pilot-duty solenoids, indicator lamps, and small contactor coils without an interposing relay. ## Relay contact life — the number that matters at 100,000 cycles The relay contacts are rated 10 million mechanical operations, but at rated load voltage the electrical endurance drops to 100,000 cycles — that is the number to budget for a valve that cycles every 10 seconds on a packaging line (roughly 11 days continuous). For DC loads, the max lamp load is 30 W (vs 200 W on AC), so a 24 VDC indicator array stays under 1.25 A per output. Optocoupler isolation on the inputs and relay isolation on the outputs keep the field wiring separate from the backplane — 500 V AC tested between the two sides. The module measures 46 mm wide by 80 mm tall by 62 mm deep — it clips onto the S7-200 DIN rail alongside the CPU and takes up one slot in the expansion chain. Plug-in I/O terminals mean the wiring harness stays put when you swap the module — useful during commissioning if the I/O count changes and the whole assembly has to come off the rail. Unshielded sensor cable runs up to 150 m; shielded runs stretch to 500 m — plenty for distributed sensors on a conveyor line.","metaTitle":"Siemens 6ES7223-1HF22-0XA0 S7-200 Digital I/O","metaDescription":"Siemens 6ES7223-1HF22-0XA0 S7-200 expansion module. 4 digital inputs (24V AC/DC) and 4 relay outputs rated 0.75 A each.
