6AG1214-1AF40-5XB0 - Siemens SIPLUS Fail-safe CPU 1214FC

The Siemens 6AG1214-1AF40-5XB0 is a robust SIPLUS fail-safe PLC based on the proven 6ES7214-1AF40-0XB0 hardware. Designed for environments with elevated humidity, temperature fluctuation, and contamination, it operates reliably from -25°C to +55°C thanks to its conformal coating. This CPU 1214FC includes onboard I/O with 14 digital inputs (DI) at 24 V DC, 10 digital outputs (DQ) at 24 V DC, and 2 analog inputs (AI) for 0–10 V DC signals. It runs on a DC 20.4–28.8 V power supply and includes 125 KB program/data memory for both logic and safety instructions.

Belonging to the SIPLUS fail-safe CPUs family, this model supports safety functionality up to SIL2 / PL d as per IEC 61508. Its compact size (11.0 x 11.5 x 8.2 cm) and lightweight design (0.368 kg) make it ideal for control cabinets with limited space. It integrates seamlessly with Siemens’ TIA Portal for combined configuration of safety and standard automation. With active product lifecycle support (PM300), the 6AG1214-1AF40-5XB0 delivers long-term serviceability backed by Siemens’ German engineering and industrial expertise.

The 6AG1214-1AF40-5XB0 is an excellent choice for Indian automation projects in environments that face temperature extremes, dust, or moisture—such as chemical plants, water treatment facilities, and outdoor conveyor systems. Its fail-safe architecture ensures process safety, making it suitable for safety interlocks, emergency stop systems, and motion control safety functions.

The onboard digital and analog I/O eliminates the need for additional modules, simplifying control panel design. Automation professionals benefit from easy deployment via TIA Portal, which allows full configuration of both standard PLC and fail-safe logic in a unified engineering environment. Its DC/DC/DC configuration ensures smooth integration with 24 V DC-based industrial power systems.

Trusted across global and Indian manufacturing sectors, the Siemens SIPLUS S7-1200 CPU 6AG1214-1AF40-5XB0 offers compact reliability for control applications that demand safety, environmental resistance, and long-term support. It’s a go-to solution for OEMs and machine builders looking to future-proof their automation with Siemens quality.
