Siemens 6ES7214-1BG40-0XB0 SIMATIC S7-1200 CPU 1214C AC/DC/Relay 14DI/10DO/2AI Programmable Logic Controller

The Siemens SIMATIC S7-1200 CPU 1214C AC/DC/Relay (6ES7214-1BG40-0XB0) is a compact programmable logic controller with 14 digital inputs, 10 relay outputs, and 2 analog inputs onboard, 150 KB integrated work memory, and a PROFINET interface, powered from 85-264V AC. It supports up to 3 communication modules, 1 signal board, and 8 signal modules for I/O expansion, with a real-time clock and up to 6 high-speed counting inputs.

Selection Notes

The AC/DC/relay power/output variant draws 85-264V AC directly and switches loads through relay outputs rated 2A resistive, suiting mixed AC/DC field devices and loads up to 2A without external interposing relays, unlike DC/DC/DC CPU 1214C variants that need a separate 24V DC supply and transistor-rated loads. With 150KB work memory and 6 HSC-capable inputs, it fits mid-size machine control needing motion or counting inputs beyond the smaller CPU 1211C/1212C models in the S7-1200 line. Step up to a higher CPU 1214C-class or CPU 1215C/1217C variant only if the application needs more onboard PROFINET ports or analog outputs than this variant's fixed I/O provides.

Applications

Used as the central controller in compact machine-control panels, packaging equipment, and process skids needing onboard relay outputs for AC/DC field loads plus PROFINET connectivity to HMIs and distributed I/O.
