6AG1214-1BG40-2XB0 - Siemens S7-1200 CPU 1214C

The Siemens S7-1200 CPU 1214C DC/DC/RLY Onboard I/O 6AG1214-1BG40-2XB0 is a high-reliability Programmable Logic Controller (PLC) from the SIPLUS S7-1200 family, engineered for rugged automation environments. Developed by Siemens, this CPU 1214C AC/DC/Relay variant offers extended temperature resistance, conformal coating, and powerful onboard I/O for demanding control applications.

The 6AG1214-1BG40-2XB0 is based on the widely used 6ES7214-1BG40-0XB0 model and enhanced under the SIPLUS platform to support operation in harsh industrial conditions. It functions reliably between -40°C and +70°C with startup capability at -25°C. Its conformal coating protects the internal components from humidity, dust, and corrosion, extending lifespan in field installations. This compact CPU 1214C AC/DC/Relay is equipped with 14 digital inputs (24 V DC), 10 relay outputs rated at 2 A, and 2 analog inputs (0–10 V DC), providing flexibility to control discrete actuators and monitor analog signals such as pressure or temperature. It operates with an AC power supply of 85–264 V at 47–63 Hz and contains 100 KB of program/data memory for moderate to complex control logic. The unit weighs 0.473 kg and measures 10.80 x 11.50 x 8.00 cm, making it a compact fit for industrial control panels. Siemens’ PM300: Active Product Lifecycle classification ensures long-term product availability, updates, and global support.

Applications of Siemens PLC 6AG1214-1BG40-2XB0
