Product Introduction
The AAI835‑S03 is a compact, high-performance analog I/O module with four isolated 4–20 mA inputs and outputs. Designed for modular control systems, it offers exceptional signal integrity, swift 10 ms update cycles, and robust 500 V isolation. Available in multiple connection styles—including KS cable and clamp‑terminal—it suits installations from compact racks to retrofit projects demanding precise, noise‑free signal transfer with modular ease.
Applications
This module is ideal for:
-
High-density analog signal acquisition in modular automation racks
-
Interfacing multiple field transmitters with centralized control systems
-
Signal conversion and retransmission in process loops across manufacturing or treatment facilities
-
Compact retrofits requiring clean, isolated analog I/O
-
Deployments where fast analog feedback and smooth integration are critical
Advantages
-
Fast, precise updates – With just a 10 ms refresh rate and ±16 µA accuracy, it supports tight control loops.
-
Clean signal integrity – 500 V isolation ensures stable, noise-aware performance.
-
Flexible mounting – Choose KS cable or clamp wiring to suit wiring needs.
-
Efficient design – Slim (~100 × 130 × 30 mm), lightweight (~0.3 kg) modular footprint for varied rack setups.
