Siemens 6ES7214-1BH50-0XB0 SIMATIC S7-1200 CPU 1214C AC/DC/RLY 14DI/10DO Programmable Logic Controller

The Siemens 6ES7214-1BH50-0XB0 is a SIMATIC S7-1200 CPU 1214C AC/DC/relay controller with 14 digital inputs and 10 relay outputs built in, powered directly from 85-264 V AC. It carries 1 MB of work memory (250 KB program / 750 KB data), two PROFINET ports with an integrated switch, and supports isochronous PROFINET (IRT) for motion-synchronized I/O.

Selection Notes

The AC/DC/RLY power type runs the CPU straight from 85-264 V AC line voltage and switches outputs through relays rated 2 A resistive or 200 W lamp load, including AC loads - pick this variant when the panel has no separate 24 V DC supply for the controller itself. The 14 DI / 10 DO count and 1 MB work memory put the 1214C above the smaller CPUs in the family for machines needing more onboard I/O, and the dual PROFINET ports with integrated switch let the CPU daisy-chain to the next PROFINET device without an external switch. IRT support with a 1-16 ms send-cycle window means this CPU can hold isochronous synchronization with servo axes if the application later adds motion.

Applications

Fits machines that need direct AC-line power and driving AC/DC loads from relay outputs without an external 24 V supply - packaging equipment, conveyor sections, and process skids with a mix of digital sensing and switched loads on a PROFINET line.
