Siemens 6ES7 216-2AD00-0XB0 Programmable Logic Controller CPU Module

The Siemens 6ES7216-2AD00-0XB0 SIMATIC S7-200 CPU216 is a compact, DC-powered PLC CPU module designed for small-scale automation, combining 24V DC I/O, serial interface options, and an integrated power supply into a single compact unit. It provides 24 digital inputs and 16 digital outputs, all rated for 24 V DC, and includes an integral 24 V DC power supply to simplify wiring for standalone control of simple machines and control panels. Two RS-485 interfaces enable MPI/PPI communications and Freeport compatibility for programming and data exchange, while on-board memory comprises 8 KB of user program memory and 5 KB of data memory (4 K words program / 2.5 K words data), supporting moderate logic and data handling tasks. The CPU216 can be expanded with up to seven additional modules to grow I/O capacity as needs evolve, and the order number 6ES7216-2AD00-0XB0 uniquely identifies this model within the S7-200 family.
