Siemens 6ES7216-2AD23-0XB8 is a SIMATIC S7-200 CN CPU 226 compact device identified by Siemens as a spare part.
It uses a DC power-supply design and integrates 24 DC digital inputs with 16 DC transistor outputs.
The CPU provides 16 or 24 KB of program memory and 10 KB of data memory.
Two PPI or user-programmable interfaces are included for the specified communication configuration.
Typical power loss is 11 W, the module dimensions are 196 x 80 x 62 mm, and Siemens states that this S7-200 CN product has CE approval only.
Verify the exact CN article, I/O wiring, interface requirements, memory configuration and cabinet fit before replacement. AMIKONG can assist with checking availability of the exact spare unit.

Serial communication through the two PPI or user-programmable interfaces.
Spare-CPU support for a verified 6ES7216-2AD23-0XB8 installation.
Confirm the exact article suffix 0XB8 and the SIMATIC S7-200 CN system requirement.
Verify the 24 V DC supply design and all supply-terminal assignments.
Match the 24 digital-input circuits and their DC signal requirements.
Match the 16 transistor-output circuits and connected load requirements.
Confirm whether the program configuration uses 16 or 24 KB and preserve the required 10 KB data configuration.
Verify both PPI or user-programmable interface connections and communication settings.
Allow for the module dimensions of 196 x 80 x 62 mm and typical power loss of 11 W.
Review the project backup and current Siemens documentation before installation or replacement.
Siemens identifies 6ES7216-2AD23-0XB8 as a spare part.
The exact article is the S7-200 CN variant and must be distinguished from other CPU 226 versions.
Current availability depends on the remaining spare-part supply.
A different CPU 226 article must not be treated as a direct replacement without engineering verification.
Replacement checks must cover the DC supply, 24 inputs, 16 transistor outputs, memory, interfaces, dimensions and project backup.
AMIKONG can assist with locating available exact spare units and reviewing candidate replacements for the verified system configuration.
