6ES7214-1HG40-0XB0 CPU 1214C DC/DC/Relay 14DI/10DO/2AI | Siemens

The Original New Siemens 6ES7214-1HG40-0XB0 SIMATIC S7-1200 CPU 1214C is a compact, high-performance programmable logic controller designed for small to medium-scale automation tasks requiring relay output switching. Featuring a DC/DC/relay power supply and onboard I/O configuration with 14 digital inputs, 10 relay outputs (2A per channel), and 2 analog inputs, this CPU offers a highly integrated solution for machine control, conveyor systems, and OEM equipment where isolated AC/DC load switching is required.

Core Engineering Highlights:
14 digital inputs (24V DC) | 10 relay outputs (2A per channel) | 2 analog inputs (0-10V) | 150 KB work memory / 4 MB load memory | 0.085 µs bit processing | PROFINET interface (1 port) | 24V DC supply (20.4–28.8V) | IP20 | –20°C to +60°C operating
