The 6ES7212-1AD30-0XB0 is a Siemens SIMATIC S7-1200 CPU 1212C compact controller, engineered for precise control in small-scale automation systems. This DC/DC/DC variant integrates 8 digital inputs (24V DC), 6 digital outputs (24V DC), and 2 analog inputs (0-10V DC) directly on the unit, eliminating the need for separate I/O modules in many applications. With a robust 25 KB program/data memory, it supports efficient logic execution and data handling. The CPU operates on a wide DC power supply range of 20.4 to 28.8 V DC, making it suitable for battery-backed or distributed setups. Each unit is 100% original and new, sourced directly from Siemens, and typically dispatched within 1 working day. Below are the detailed technical specifications based on official Siemens documentation.
