It's the high-density relay output option for the S7-1200 family — 32 I/O points in a 70 mm wide housing that snaps onto the standard DIN rail alongside the CPU. The 16 relay outputs are individually rated 2 A at 24 V DC (resistive or inductive), and the module carries a lamp load rating of 30 W on DC and 200 W on AC. That 2 A per channel is the hard limit — no short-circuit protection onboard, so the buyer must fuse each output group externally. The input side expects a '1' signal between +15 and +30 V DC, drawing a typical 4 mA per channel, with a maximum transition time of 200 µs — fast enough for most discrete sensing but not for high-speed counting. Isolation is tested at 1500 V AC between outputs and the backplane, and 500 V AC between inputs. The module draws 165 mA from the 24 V DC backplane supply. With 16 inputs and 16 relay coils to energize, that draw is within the S7-1200 CPU's internal power budget — but if all 16 relays are held on simultaneously, the total coil current plus input current must be checked against the CPU's 24 V DC output rating. The module is 70 mm wide, 100 mm high, and 81 mm deep — it occupies one slot to the right of the CPU on the DIN rail. The IP20 enclosure means it's for a clean, dry control cabinet only; no washdown or outdoor mounting. The relay outputs are dry-contact form A (normally open) with galvanic isolation between channels, so each output can switch a separate circuit at a different potential, up to the isolation voltage. Inputs can be wired in parallel for higher current-sinking capacity. Unshielded input cable runs up to 150 m; shielded runs up to 500 m. That's generous for a distributed I/O layout within a plant — the shielded length covers most intra-building runs without a remote I/O rack.","metaTitle":"Siemens 6ES7288-2DR32-0AA0 SM 1223, 16DI/16DO Relay, 24 V DC","metaDescription":"Siemens 6ES7288-2DR32-0AA0 SM 1223 digital I/O module: 16 inputs 24 V DC, 16 relay outputs 2 A, IP20, CE marked.
