It carries 8 digital inputs and 6 transistor outputs, all DC, with 4 KB program memory and 2 KB data memory, and is expandable via PROFIBUS DP. ## I/O count and power budget for the BOM line With 8 digital inputs and 6 transistor (sourcing) outputs, this CPU covers small machine control or standalone station logic without needing an expansion module for basic I/O. The 5 W typical power loss means a 24 VDC supply rail sized for the load plus 5 W headroom keeps the thermal rise inside the enclosure manageable. ## Panel fit and lifecycle status Lifecycle stage is listed as current, meaning it remains in the Siemens spare-parts channel for existing field installations.","metaTitle":"Siemens 6ES7212-1AB23-0XB8 S7-200 CPU 222, 8 DI/6 DO DC","metaDescription":"Siemens 6ES7212-1AB23-0XB8 S7-200 CN CPU 222 spare part. 8 digital inputs, 6 transistor outputs, 4 KB program memory.
