The inputs accept 24 V DC signals (15 V to 30 V DC for a logic '1', 0 to 5 V for '0') and are isolated from the backplane via optocouplers, so field wiring faults don't take out the CPU bus. The 16 relay outputs are rated 0.75 A each for resistive or inductive loads, with a maximum lamp load of 200 W on AC or 30 W on DC — good for small contactors, pilot lights, and solenoid valves. Power comes from either 24 V DC or 24 V to 230 V AC, so it can share a control transformer with the rest of the panel without a separate DC supply. ## Relay outputs vs transistor — why it matters This module uses electromechanical relays, not solid-state transistors — each output switches up to 0.75 A at up to 250 V AC or 30 V DC, but the mechanical life is 10 million cycles and only 100,000 at rated load voltage. The relay contacts are isolated in groups of four, so you can mix AC and DC loads across groups without cross-talk, but there's no short-circuit protection on the outputs — fuse each group externally.","metaTitle":"Siemens 6ES7223-1PL22-0XA0 S7-200 I/O Module","metaDescription":"Siemens 6ES7223-1PL22-0XA0 S7-200 expansion module: 16 digital inputs, 16 relay outputs, 24V AC/DC supply, 62 mm depth.
