Product details
Overview
The 6ES7214-1AF50-0XB0 is a Siemens SIMATIC S7-1200 G2 fail-safe compact CPU 1214FC with DC/DC/DC topology — 14 digital inputs and 10 digital outputs all at 24 V DC, running on a 28.8 V DC supply. Program memory sits at 300 KB with 750 KB of data memory and 20 KB of retentivity, placing it in the mid-range of the fail-safe S7-1200 G2 line.
Onboard I/O provides 14 digital inputs and 10 digital outputs at 24 V DC, all sink/source configurable. The DC/DC/DC variant means the outputs switch 24 V DC directly — no relay base — which suits high-cycle solenoid valves, contactor coils and indicator banks where relay wear would be a maintenance item. The 28.8 V supply rail is the nominal maximum; the CPU accepts 20.4 V DC minimum, giving headroom for a sagging 24 V bus on a long cable run.
Applications
Fail-safe CPUs of this class are specified for machinery where a safety-rated controller is mandatory: packaging lines with guarding interlocks, press and forming equipment, robotic cells, conveyor systems with emergency-stop zones, and process skids requiring SIL-rated shutdown logic. The S7-1200 G2 platform integrates into TIA Portal for unified standard and safety engineering.
The 6ES7214-1AF50-0XB0 carries an active lifecycle status — Siemens lists it as a current production item with no announced end-of-life.
