Failsafe CPU for S7-1200 G2
The Siemens 6ES7212-1HF50-0XB0 is a failsafe CPU from the SIMATIC S7-1200 G2 series, built for safety-critical control in automation systems. It provides 8 digital inputs at 24 VDC and 6 relay outputs rated at 2 A, with 200 KB program and 500 KB data memory — enough for medium-sized safety logic. This is the fail-safe variant of the 1212C, used in applications like emergency stop, light curtains, and guard interlocking. For any line running S7-1200 safety functions, this is a critical spare to keep one in the cabinet before it fails.
