6AG1212-1BE40-2XB0 - Siemens PLC S7-1200 CPU 1212C AC/DC/Relay

The Siemens PLC S7-1200 CPU 1212C AC/DC/Relay 6AG1212-1BE40-2XB0 is a rugged and compact Programmable Logic Controller (PLC) designed for harsh industrial environments. Built on the proven Siemens S7-1200 platform, this SIPLUS CPU 1212C model comes with a conformal coating, wide temperature tolerance, and AC power compatibility—ideal for control systems operating in extreme conditions.

The 6AG1212-1BE40-2XB0 is part of the Siemens SIPLUS S7-1200 family and is based on the 6ES7212-1BE40-0XB0 architecture. This enhanced version is engineered with a conformal coating for superior protection against humidity, dust, and corrosive environments. It operates reliably in a temperature range from -40°C to +70°C, with startup possible even at -25°C, making it suitable for outdoor and heavy-duty industrial applications. This CPU 1212C AC/DC/Relay variant features 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 discrete and analog devices. The controller runs on a wide AC power supply of 85–264 V at 47–63 Hz, ensuring compatibility with standard industrial power sources. Its 75 KB program/data memory provides ample space for mid-range control logic and automation routines. Weighing 0.409 kg and measuring just 10.00 x 10.50 x 8.20 cm, the device is optimized for installation in compact control panels. Backed by PM300: Active Product Lifecycle support, the 6AG1212-1BE40-2XB0 offers long-term availability and Siemens’ global technical reliability.
