6AG1212-1HE40-4XB0 - Siemens 1212C DC DC Compact CPU

The Siemens 1212C DC/DC/RLY Compact CPU 6AG1212-1HE40-4XB0 is a reliable PLC built for demanding industrial environments. Part of the SIPLUS S7-1200 series, this CPU 1212C DC/DC/Relay version is designed by Siemens with enhanced environmental protection through conformal coating and temperature resilience, making it ideal for critical automation needs.

The 6AG1212-1HE40-4XB0 is based on the standard 6ES7212-1HE40-0XB0 model and upgraded under the SIPLUS S7-1200 platform for extended durability. It operates within a temperature range of -20°C to +60°C, making it suitable for dusty, humid, or semi-outdoor industrial environments. With a DC power supply range of 20.4–28.8 V, this compact CPU delivers consistent control performance in voltage-sensitive operations. This compact PLC includes 8 digital inputs (24 V DC), 6 relay outputs rated at 2 A, and 2 analog inputs (0–10 V DC), offering flexible control for both digital logic and analog signal processing. With a program/data memory of 75 KB, the unit can handle moderate automation logic while maintaining high processing reliability. Its compact footprint of 10.00 x 10.50 x 8.20 cm and light weight of 0.323 kg make it a perfect fit for space-constrained panels. Backed by PM300: Active Product Lifecycle classification, Siemens ensures long-term support, firmware updates, and global integration reliability for the 6AG1212-1HE40-4XB0.
