Product Overview
Model: AAI141‑S50/A4S00
Brand: (redacted)
Product Series: AAI analog input/output integration family
Product Description
The AAI141‑S50/A4S00 is an integrated analog input/output module tailored for compact and efficient control systems. It elegantly combines the ability to receive analog field signals (such as 4–20 mA or 0–10 V) and to retransmit processed analog output signals within a single module. With both input and output seamlessly integrated, it stands out for simplifying panel layouts, reducing wiring, and delivering consistent performance.
Equipped with robust isolation, configurable signal ranges, and versatile mounting options (DIN‑rail or rack), this model serves as a dual-function device that brings clarity and precision to process control environments.
Product Applications
This module is well-suited to multiple industrial instrumentation scenarios, including:
-
Consolidating analog I/O for process variables like temperature, pressure, or flow.
-
Retrofitting legacy panels with space-efficient analog I/O.
-
Distributing both input and output in one module to simplify loop wiring.
-
Offering isolated analog coupling in hazardous or noise-prone areas.
-
Acting as a serial I/O bridge in tightly populated control racks.
Product Advantages
Distinct benefits of this module include:
-
Dual-functionality reduces module count and system complexity.
-
High accuracy (around ±0.1 % of span) ensures trustworthy control feedback.
-
Galvanic isolation (typically ~1,500 Vrms) guards against noise and ground loops.
-
Compact dimensions optimize panel real estate.
-
Front-panel switch programming with optional external setup keeps configuration agile.
-
Reliable across industrial temperature ranges and supply voltage fluctuations.
-
Friendly support for maintenance and module swapping in the field.
