Siemens 6ES7214-1AD21-0XB0 Programmable Logic Controller Module

Siemens 6ES7214-1AD21-0XB0 is a CPU224 compact module from the SIMATIC S7-200 family, engineered for compact, DC-powered discrete control tasks. It provides 14 digital inputs and 10 digital outputs at 24 V DC, all housed in a single compact unit designed for panel mounting and space-constrained control cabinets. The module carries 8 KB of program memory and 5 KB of data memory, enabling compact control logic and data handling for small automation tasks. It includes an optional PROFIBUS DP interface that is extendable, allowing reliable fieldbus communication with other Siemens controllers and compatible devices in an industrial network. Typical applications include small packaging lines, conveyor control, simple machine sequencing, and process-automation tasks where straightforward I/O and deterministic response are required. Designed for seamless integration within the S7-200 ecosystem, this CPU224 module supports straightforward programming and reconfiguration as automation needs evolve.
