Product details

The 6AG1212-1HE40-2XB0 is the SIPLUS variant of the S7-1200 CPU 1212C, rated for -40 to 70 °C ambient. It runs the same firmware as the standard 6ES7212-1HE40-0XB0 and supports FBD, LAD, and SCL programming. The PROFINET interface includes Modbus TCP, UDP, and a web server. PID controller is baked in, so no separate function block required for basic loops. Power supply is 24 V DC with L+ minus 4 V min. The CPU is not expandable beyond the onboard I/O.

Frequently asked questions
