It packs 4 digital inputs accepting AC or DC voltage and 4 relay outputs rated at 2 000 mA per channel, making it a compact mixed-signal block for extending an S7-200 base unit. ## Input and output specs that decide the fit The 4 inputs accept AC/DC voltage — a flexible input type that lets you wire either 24 VDC sensors or 120 VAC limit switches without a separate input module. The typical signal-1 current draw is 4 mA per input, which matters when budgeting the CPU's internal 24 VDC supply capacity. The 4 relay outputs are rated 2 000 mA per channel — enough for direct switching of small contactors, solenoid valves, or indicator banks up to 250 VAC. Note that short-circuit protection is not provided on the outputs, so external fusing or a downstream MCB is needed per channel or group. Physical fit: the module measures 46 mm wide, 80 mm high, and 62 mm deep — it occupies a single S7-200 expansion slot and extends the CPU's width by 46 mm on the DIN rail. The 2 W typical power loss is drawn from the backplane bus, not an external supply. ## Sourcing and lifecycle — what to expect This is a current-production part, listed as a spare for the S7-200 CN series. The S7-200 platform has been superseded by the S7-1200 and S7-1500 families, but this EM 223 module remains available through independent distribution for installed-base support. The module carries CE approval only, per the manufacturer's description.","metaTitle":"Siemens 6ES7223-1HF22-0XA8 EM 223, 4 DI / 4 DO Relay","metaDescription":"Siemens 6ES7223-1HF22-0XA8 SIMATIC S7-200 CN EM 223 expansion module. 4 digital inputs AC/DC, 4 relay outputs rated 2 A.
