Yokogawa AAI835-S50 Isolator | 4-20mA, Input/Output/Power Isolation, DIN Rail

Yokogawa AAI835-S50 isolator specifications. 4-20mA isolator, triple isolation, input/output/power, DIN rail mount.

Product Overview

The Yokogawa AAI835-S50 is a universal signal isolator engineered for reliable process control and measurement applications. It establishes full galvanic isolation between the input signal, output signal, and power supply. Accepting a standard 4-20mA input, it delivers a precise, isolated 4-20mA output, effectively eliminating ground loops, suppressing electrical noise, and safeguarding system integrity in industrial settings.

Key Features

  • Triple Isolation:​ Full galvanic isolation between input, output, and power supply

  • High Accuracy:​ ±0.1% accuracy for reliable analog signal transmission

  • Wide Power Supply Range:​ Operates from 20-55V DC

  • Ground Loop Elimination:​ Prevents noise and interference from differing ground potentials

  • System Protection:​ Shields control system I/O from field-side voltage transients

  • Compact DIN Rail Design:​ Efficient use of panel space

  • Optional Local Display:​ LCD module for real-time signal monitoring

  • Easy Setup:​ Simple calibration via local zero and span adjustments

  • Industrial Robustness:​ Built for reliable performance in demanding environments

Applications

  • Isolating 4-20mA signals between field instruments and control systems (DCS/PLC)

  • Breaking ground loops in analog measurement and control circuits

  • Protecting sensitive control room equipment from field-side electrical hazards

  • Signal conditioning in general industrial process applications

  • Use in industries such as oil & gas, chemical processing, water treatment, and power generation

Important Notes

  1. Requires an external, isolated 20-55V DC power supply

  2. This model does not support HART digital communication

  3. Correct wiring of input, output, and power terminals is critical to maintain isolation integrity

  4. Ensure the output load does not exceed the specified 500Ω limit

  5. Input and output ranges may require configuration via local adjustments
