It snaps onto the right side of the CPU, extending the I/O count without changing the backplane or power budget. The module draws its field-side power from the 24 VDC sensor supply, not the CPU bus. ## Input/output specs that decide the fit Eight sourcing inputs accept 24 VDC nominal. The eight transistor outputs sink 0.5 A continuous each. The 0.5 A per-output ceiling means each channel drives a small solenoid, indicator lamp, or contactor coil directly — but a group of outputs feeding a larger load needs an interposing relay. Total module current from the 24 VDC supply is limited by the CPU's backplane current budget.","metaTitle":"Siemens 6ES7223-1BH20-0XA0 EM 223, DI8/DO8x24VDC 0.5A","metaDescription":"Siemens 6ES7223-1BH20-0XA0 EM 223 expansion module: 8 digital inputs + 8 transistor outputs, 24 VDC, 0.5 A per output.
