Overview
The 6ES7214-1HH50-0XB0 is a Siemens SIMATIC S7-1200 G2 compact CPU 1214C with DC power supply and relay outputs. It carries 14 digital inputs at 24 V DC and 10 relay outputs rated 2 A, with 250 KB of program memory and 750 KB of data memory. This unit runs on a 28.8 V DC supply and is in active production, making it a current-order option for new machine builds and BOM replenishment.
Function & operation
The CPU 1214C executes the user program and coordinates onboard I/O plus expansion modules via the S7-1200 backplane. The 250 KB program memory handles moderate machine logic with data handling; the 750 KB data memory supports larger tag tables and recipe storage than the entry-level 1211C or 1212C CPUs. The 14 digital inputs sink 24 V DC signals from sensors and pushbuttons; the 10 relay outputs switch loads up to 2 A per channel, suitable for contactors, solenoid valves and indicator lamps without external interposing relays. The 20 KB retentive memory holds critical counters and flags through a power cycle.
Applications
S7-1200 G2 CPUs of this class are specified for compact machine control — packaging cells, conveyor sections, pump skids, small assembly stations and OEM equipment where a standalone controller with embedded I/O replaces a larger rack system. The relay outputs suit mixed AC/DC load switching common in industrial panels.
