Siemens 6ES7214-1HG40-0XB0 Analog Input Module

Siemens 6ES7214-1HG40-0XB0 is a SIMATIC S7-1200 CPU 1214C that combines a compact controller with built‑in analog and digital I/O: 2 analog inputs (0–10 V DC) and 14 digital inputs (24 V DC), plus 10 digital outputs (relay, 2 A). The module is a DC/DC/Relay variant powered from a 24 V DC supply in the range of 20.4–28.8 V DC and carries 150 KB of program/data memory, aligning with the S7-1200 family’s small-footprint automation solutions. It provides two AI inputs for direct voltage sensing and a robust digital I/O set (14 DI, 10 DO) to support straightforward machine control, process monitoring, and simple closed-loop tasks where two analog signals are read while digital I/O handles sensors, interlocks, and actuators.
