Spare-part CPU for existing S7-200 CN lines
The 6ES7214-1AD23-0XB8 is a Siemens S7-200 CN CPU 224 compact device, designated as a spare part for existing installations. It runs on a DC power supply and provides 14 digital inputs (DC) and 10 digital outputs (transistor type). Program memory is 8 or 12 KB, data memory is 8 KB, and the unit is expandable via PROFIBUS DP. This S7-200 CN variant carries CE approval only.
Panel fit and power budget
The CPU measures 120.5 mm wide, 80 mm high, and 62 mm deep — a standard footprint for the S7-200 family that fits existing DIN-rail layouts without re-drilling. Typical power loss is 7 W, which is modest for a compact PLC; the 24 VDC supply rail should be sized to handle this plus the I/O load.
