Siemens QLCAIAAN High-Precision Analog Input Module

Product Description

The Siemens QLCAIAAN is an 8-channel high-precision analog input module built for APACS+ and QuadLog control systems. It captures voltage and current signals from sensors and transducers, delivering accurate digital conversion for process monitoring and automation control. Designed for demanding industrial environments, this module offers compact dimensions (90 × 90 × 60 mm) and robust diagnostic features to ensure reliable operation.

The QLCAIAAN supports multiple voltage ranges (±10 V, 0–10 V, ±5 V, ±1 V) and standard current loops (0–20 mA, 4–20 mA), with a typical 16-bit resolution for precise signal measurement. Operating at 24 VDC with ~300 mA current consumption, it integrates seamlessly into APACS+ or QuadLog systems, providing consistent performance for industrial or research applications.
