6AG1214-1HG40-4XB0 - Siemens Compact CPU 1214C DC DC Relay

The Siemens Compact CPU 1214C DC/DC/Relay 6AG1214-1HG40-4XB0 is a high-performance Programmable Logic Controller (PLC) from the SIPLUS S7-1200 family. Designed by Siemens for use in industrial environments, this CPU 1214C DC/DC/Relay variant features compact design, conformal coating, and flexible onboard I/O, making it a reliable choice for rugged automation systems.

The 6AG1214-1HG40-4XB0 is based on the standard 6ES7214-1HG40-0XB0 and enhanced under Siemens’ SIPLUS platform, offering a conformal coating for protection against moisture, dust, and corrosive environments. This Compact CPU 1214C DC/DC/Relay supports a temperature range of -20°C to +60°C, making it suitable for semi-outdoor and harsh cabinet conditions. It runs on a DC power supply of 20.4–28.8 V and includes a powerful 100 KB of program/data memory to manage complex automation logic and communication tasks. The onboard I/O configuration features 14 digital inputs (24 V DC), 10 relay outputs rated at 2 A, and 2 analog inputs (0–10 V DC), allowing integration of both discrete devices and analog sensors such as pressure, level, or temperature transmitters. With compact dimensions of 11.00 x 11.40 x 8.20 cm and a net weight of 0.394 kg, the controller is optimized for space-saving installations. It carries the PM300: Active Product Lifecycle designation, ensuring Siemens’ long-term support and availability.
