It provides 16 digital inputs at 24 V DC and 16 digital outputs at 24 V DC, each rated for 0.75 A with resistive or inductive loads. The module draws up to 160 mA from the 5 V DC backplane bus and dissipates 6 W typical. Inputs accept sink or source wiring (2-wire sensor compatible) with a signal \"1\" threshold of 15 to 30 V DC and a 4.5 ms max turn-on time. The 6ES7223-1BL22-0XA0 carries a current lifecycle stage, but the manufacturer explicitly lists it as a spare part for the S7-200 platform — a legacy system no longer in active new-installation promotion. This means the module is not a standard production item stocked in volume; availability is confirmed per RFQ through independent distribution channels. Buyers holding an S7-200 BOM line should treat this as a last-time-buy or surplus-channel part and quote quantities against the specific lot. ## Physical fit and isolation details Inputs and outputs are optocoupler-isolated from the backplane bus, with 500 V AC isolation tested between channels and the logic side. Outputs have inductive shutdown voltage clamped to L+ (-48 V), and the maximum current per conductor group is 3 A, split as 3 / 3 / 6 across the terminal blocks.","metaTitle":"Siemens 6ES7223-1BL22-0XA0 EM 223 Digital I/O","metaDescription":"Siemens 6ES7223-1BL22-0XA0 EM 223 I/O module: 16 digital inputs 24V DC, 16 digital outputs 0.75A/ch.
