It snaps onto the S7-200 rail and draws power from the backplane or an external 24 V DC supply (72 mA max). The inputs accept 15–30 V DC for signal '1', with a 4.5 ms max turn-on time; the relay outputs switch up to 0.75 A each on resistive or inductive loads, with mechanical endurance rated at 10 million cycles and 100,000 at rated load voltage. ## Supply flexibility and isolation The module runs on either 24 V DC or 24–230 V AC — same terminals, no jumper change. Inputs are optocoupler-isolated from the backplane; outputs are relay-isolated in groups of four. Isolation tested at 500 V AC between channels and the bus. That means you can land different field potentials on the same module without chasing ground loops — useful when half the panel runs 24 V sensors and the other half 120 V pilot lights.","metaTitle":"Siemens 6ES7223-1PH22-0XA0 EM 223, 8DI/8 Relay DO","metaDescription":"Siemens 6ES7223-1PH22-0XA0 EM 223 expansion module with 8 digital inputs and 8 relay outputs.

This is a standard EM 223 expansion module designed for the S7-200 family. It connects via the ribbon cable to any S7-200 CPU (CPU 221, 222, 224, 224XP, 226) and is recognised automatically on power-up. No configuration needed beyond assigning the I/O addresses in the software."},{"question":"What is the output rating for 6ES7223-1PH22-0XA0?","answer":"Each relay output is rated 0.75 A maximum on resistive or inductive loads. The total current per conductor group is limited to 8 A. On lamp loads, the limit is 200 W with AC supply or 30 W with DC. Mechanical life is 10 million cycles; at rated load voltage expect 100,000 operations."},{"question":"Where can I buy 6ES7223-1PH22-0XA0?","answer":"Available to order through our distribution channel.
