It runs on a 24 VDC supply and provides 24 digital inputs and 16 transistor-sourced digital outputs, with no relay outputs on board. Program memory is 16 or 24 KB, with 10 KB of data memory, and two PPI interfaces that can also be user-programmed for other protocols. The unit draws a typical power loss of 11 W. The CPU measures 196 mm wide, 80 mm tall, and 62 mm deep — it occupies the same footprint as the standard S7-200 CPU 226 and mounts directly onto the DIN rail or panel plate in the existing enclosure.","metaTitle":"Siemens 6ES7216-2AD23-0XB8 S7-200 CPU 226, 24 DI / 16 DO DC","metaDescription":"Siemens 6ES7216-2AD23-0XB8 S7-200 CN CPU 226 spare part. 24 DC inputs, 16 transistor outputs, 11 W power loss.
