Siemens 6ES7531-7KF00-0AB0 Programmable Logic Controller Module

The SIMATIC S7-1500 AI 8xU/I/RTD/TC ST analog input module provides eight input channels for measuring voltage, current, RTD and thermocouple sensors with 16‑bit resolution. It includes 4 RTD measurement channels and supports a common‑mode voltage of 10 V, with diagnostics and hardware interrupts to help detect wiring or sensor issues. Delivery includes the infeed element, shield bracket and shield terminal; front connector (screw terminals or push‑in) must be ordered separately. The module is powered from 24 V DC, draws up to 255 mA on the backplane and consumes about 0.7 W from the backplane, with firmware version V2.0.0 and FW upgrade possible; it provides I&M data (I&M0–I&M3) and is configurable via STEP 7 /TIA Portal.
