YOKOGAWA AAI143-H53/K4A00 Analog Input Module

Description

The YOKOGAWA AAI143-H53/K4A00 is a 16-channel isolated analog input module for the CENTUM VP and CENTUM CS 3000 Distributed Control Systems (DCS), converting 4–20 mA DC signals from field transmitters into digital values for process monitoring and control. The H53 suffix provides HART digital communication, ISA Standard G3 conformal coating for corrosive gas resistance, and an extended operating temperature range. The K4A00 option includes the ATK4A-00 KS cable interface adapter for direct connection to AEA4D terminal boards.

Features

  • 16 fully isolated 4–20 mA input channels with HART protocol support

  • ISA Standard G3 conformal coating for sulfur- and chlorine-based corrosive environments

  • Extended operating temperature range from –20 to +70°C

  • Per-channel selectable 2-wire or 4-wire transmitter configuration

  • Hot-swappable design for maintenance without system shutdown

Technical Specifications

  • Input Channels: 16 fully isolated channels

  • Input Signal: 4 to 20 mA DC current loop

  • Allowable Input Current: Up to 24 mA continuous

  • Input Resistance (Power ON): 270 Ω at 20 mA, 350 Ω at 4 mA

  • Input Resistance (Power OFF): 500 kΩ or greater

  • Measurement Accuracy: ±16 µA

  • Temperature Drift: ±16 µA per 10°C

  • Data Update Period: 10 ms

  • Withstanding Voltage: 1500 V AC for 1 minute (input to system)

  • Transmitter Power Supply: 19.0 V to 25.5 V DC with 25 mA current limiting

  • Wiring Configuration: 2-wire or 4-wire selectable per channel via hardware pins

  • Communication Protocol: HART (digital communication on all channels)

  • Current Consumption: 230 mA at 5 V DC; 540 mA at 24 V DC

  • Operating Temperature: –20 to +70°C

  • Storage Temperature: –40 to +85°C

  • Environmental Protection: ISA Standard G3 conformal coating

  • Interface Adapter: ATK4A-00 KS cable interface (included with /K4A00)

  • Weight: 0.3 kg
