Siemens 6ES7531-7QD00-0AB0 SIMATIC S7-1500 Analog Input Module 4 Channel 24V DC

4‑channel analog input module for SIMATIC S7‑1500 and ET 200MP systems, supporting voltage, current, RTD and thermocouple signals with 16‑bit resolution and 0.3% accuracy.

The Siemens 6ES7531‑7QD00‑0AB0 is a universal analog input module designed for high‑precision signal acquisition across a wide range of industrial sensors. Four configurable channels support voltage (0‑10V, ±10V), current (0‑20mA, 4‑20mA), RTD (Pt100, Pt1000) and thermocouple (Types B, E, J, K, N, R, S, T) inputs, with two dedicated channels for resistance and RTD measurement. Advanced diagnostics and hardware interrupts enable rapid fault detection and process monitoring. The module includes a push‑in front connector, infeed element, shield bracket and shield terminal, offering streamlined commissioning and secure field wiring.
