Siemens 6ES7214-1AD23-0XB0 Programmable Logic Controller Module

The Siemens 6ES7214-1AD23-0XB0 SIMATIC S7-1200 analog I/O module provides two analog inputs and two analog outputs to interface real-world signals with the PLC. It accepts voltage or current signals on the inputs and provides configurable voltage or current outputs (for example 0–10 V or 0/4–20 mA), all at a 12‑bit resolution, and is powered from the S7‑1200 backplane with 24 V DC. Mounting options include DIN‑rail or S7‑1200 bus mounting, and the module features IP20 protection with LED indicators for channel and module status, with integrated communication on the CPU bus and PROFINET/Ethernet as supported by the CPU. Common applications span process control, HVAC, water/wastewater treatment, material handling lines, and environmental monitoring where precise analog signal acquisition and control are required.
