Siemens 6ES7214-1HG40-0XB0 SIMATIC S7-1200 CPU 1214C DC/DC/Relay 14DI/10DO/2AI Programmable Logic Controller

Siemens 6ES7214-1HG40-0XB0 is a SIMATIC S7-1200 CPU 1214C, DC/DC/relay version, with 14 integrated 24 V DC digital inputs, 10 relay outputs rated 2 A each, and 2 analog voltage inputs on board. It has 150 KB of work memory, an integrated PROFINET interface supporting up to 16 connected IO devices, and runs from a 20.4-28.8 V DC supply drawing 500 mA typical.

Selection Notes

The 1214C sits above the 1212C in the S7-1200 line on I/O count (14DI/10DO/2AI) and offers 150 KB work memory, more than the smaller CPUs in the line - pick it when the application needs the extra local I/O without adding a signal module. The relay-output (DC/DC/relay) variant switches AC or DC loads directly up to 2 A per point, unlike a DC/DC/DC variant's transistor outputs, which is useful for driving contactors or pilot lights without an interposing relay. A single onboard PROFINET port with up to 16 connected IO devices covers most single-cell machines; multi-cell lines needing PROFIBUS or AS-Interface require an added communication module.

Applications

Used as the main controller on standalone machines and small production cells needing local relay-switched outputs for contactors, solenoid valves, or indicator lamps alongside PROFINET connectivity to HMI panels and upstream SCADA.
