AAI143-H53/K4A00 | Yokogawa | Analog Input Module

Product Overview

The Yokogawa AAI143-H53/K4A00 is a high-density analog input module engineered for the CENTUM VP distributed control system. It processes 16 channels of 4 to 20 mA signals and supports full digital communication via the HART protocol. This specific configuration includes enhanced environmental protection and a dedicated cable interface adapter. We supply this module as 100% Brand New and Original equipment.

Engineering Advantages

The AAI143-H53/K4A00 excels in harsh industrial environments thanks to its G3-compliant conformal coating, which resists corrosive gases and moisture. Its 16-channel high-density design saves critical cabinet space, while the 1500 V AC isolation safeguards the core control system from massive field-side electrical surges. The pre-installed K4A00 adapter streamlines installation by providing a direct, secure interface to AEA4D terminal boards, eliminating manual wiring errors and reducing commissioning time.

FAQs

• What is the benefit of the "H" designation?The "H" stands for HART protocol support, allowing your system to perform remote calibration, diagnostics, and device management directly through the analog signal wiring.

• Can this module operate in extreme climates?Yes, the "3" suffix confirms the module operates reliably from -20 to 70 °C, making it suitable for unconditioned control rooms or outdoor-mounted cabinets.

• How do I switch between 2-wire and 4-wire transmitters?You can configure each channel independently by setting the physical pins located on the module, allowing for a mix of self-powered and loop-powered field devices.

• Is the K4A00 adapter removable?The K4A00 is a dedicated KS Cable Interface Adapter designed specifically for seamless integration with AEA4D terminal boards; it ensures the most reliable connection for high-channel-count applications.
