Spare-part designation and CE-only approval
The Siemens 6ES7212-1BB23-0XB8 is a CPU 222 compact device from the S7-200 CN line, marked as a spare part. It carries CE approval only — no UL or CSA listing is on record for this variant.
I/O count and relay output type
The CPU provides 8 digital inputs and 6 relay outputs.
PROFIBUS DP expandability
The CPU 222 is PROFIBUS DP expandable via an attached EM 277 module, allowing it to participate as a DP slave on a PROFIBUS network. Without the module, the onboard port is a standard PPI multi-point interface for programming and HMI.
Compact dimensions for panel fit
At 90 mm wide, 80 mm tall, and 62 mm deep, the CPU 222 fits a tight enclosure footprint. The depth is shallow enough to clear a standard 80 mm deep DIN-rail enclosure door without interference.
