The 6AG1212-1HE31-4XB0: Power supply range is 20.4 V to 28.8 V DC. The 100 x 90 x 75 mm housing mounts on standard DIN rail. Integrated backup time of 480 h preserves retentive data during power loss. The PROFINET interface supports autonegotiation and autocrossing, simplifying cable plant. The CPU forces I/O from the engineering tool for debugging, and includes a PID controller block for loop control without an external module. Alarm handling and data logging are supported via the integrated memory.
This is a SIPLUS variant rated for ambient conditions from -40 to 70 °C, suitable for unheated areas, cold storage, or outdoor enclosures where standard S7-1200 CPUs would require derating or heating.
