Description

Siemens 6ES7531-7KF00-0AB0 S7-1500 Analog Input Module AI 8xU/I/RTD/TC ST 16-Bit

8-channel analog input module for the SIMATIC S7-1500 PLC system. Accepts voltage, current, RTD, and thermocouple signals with 16-bit resolution and 0.3% accuracy.

Specifications & What's Included

  • 8 input channels (grouped in sets of 8)
  • Input types: Voltage (U), Current (I), RTD (4 channels), Thermocouple (TC)
  • 16-bit resolution, 0.3% accuracy
  • Supply: 24 VDC, 220 mA
  • Common mode voltage: 10 V
  • Diagnostics and hardware interrupts supported
  • DIN rail mount form factor
  • Includes infeed element, shield bracket, and shield terminal
  • CE, UL, EAC certifications

Applications

This module integrates analog sensors into S7-1500 automation systems. RTD and thermocouple inputs serve temperature monitoring in industrial processes. Voltage and current channels support pressure transducers, load cells, and general analog instrumentation. Commonly deployed in manufacturing, HVAC controls, and process automation environments requiring multi-type sensor input consolidation.

Condition: Used
This Siemens 6ES7531-7KF00-0AB0 SIMATIC S7-1500 Analog Input Module has been inspected and is in good used condition. It was pulled from a working environment where it was in active use. The module body is clean overall; the photos show some corrosion on the DIN rail mounting clip, which is cosmetic and does not affect the module's function. The terminal connector blocks are intact and the backplane connector appears undamaged. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
