6AG1212-1AE40-2XB0 - Siemens SIPLUS S7-1200 CPU 8 DI 6 DQ I/O

The Siemens SIPLUS S7-1200 CPU 8 DI 6 DQ I/O 6AG1212-1AE40-2XB0 is a ruggedized PLC designed for extended temperature ranges and harsh industrial environments. Manufactured by Siemens, this SIPLUS CPU 1212C DC/DC/DC model is based on the proven S7-1200 platform and features a conformal coating for added durability, making it ideal for mission-critical automation in extreme conditions.

The 6AG1212-1AE40-2XB0 belongs to the Siemens SIPLUS S7-1200 family and is engineered for applications that demand high reliability under extreme operating conditions. It is derived from the base model 6ES7212-1AE40-0XB0 but enhanced with a conformal coating and a wide operating range of -40°C to +70°C, with startup possible at -25°C. This makes it especially suited for outdoor, mining, cold storage, and high-temperature industrial zones. The CPU 1212C DC/DC/DC configuration provides onboard 8 digital inputs (24 V DC), 6 digital outputs (24 V DC), and 2 analog inputs (0–10 V DC), offering flexible signal handling in compact control systems. With a DC power supply range of 20.4–28.8 V, it delivers stable operation in voltage-variable setups. A program/data memory of 75 KB enables efficient execution of control logic for moderate to complex automation tasks. This SIPLUS variant measures just 10.00 x 10.50 x 8.30 cm and weighs 0.340 kg, making it an excellent fit for space-constrained installations. Classified under PM300: Active Product Lifecycle, the 6AG1212-1AE40-2XB0 guarantees firmware updates, global support, and long-term availability, further strengthening its position as a trusted PLC for demanding industrial environments.
