Yokogawa AAI143-H50/K4A00 16-channel Analog Input Module
Product Brief Description
Yokogawa AAI143-H50/K4A00 is a 16-channel analog input module for CENTUM VP FIO I/O system. It accepts 4–20mA current signals from field transmitters, supports HART communication, and the suffix /K4A00 defines its terminal block and isolation configuration. This module converts analog field signals into digital data and transmits to FCU via ESB bus for process monitoring and closed-loop control.
Product Functions
- Collect 4–20mA analog signals from pressure, flow, temperature and level transmitters
- Built-in HART pass-through function to read transmitter diagnostic and parameter data
- 16 isolated input channels with overvoltage and reverse polarity protection
- Signal conversion and data upload to FCU through ESB high-speed bus
- Channel-by-channel fault diagnosis, wire break detection and alarm output
- Front LED indicators for module run status, communication and channel faults
- Support hot-swap operation without shutting down the DCS control system
Application Scenarios
- Petrochemical, refinery and natural gas plant CENTUM VP DCS systems
- Thermal power, combined cycle unit boiler and turbine process monitoring
- Chemical, pharmaceutical and water treatment continuous production lines
- Field HART instrument signal acquisition in distributed FIO I/O cabinets
- DCS I/O cabinet renovation, spare replacement and system expansion projects
FAQ
Q: What does H50 and /K4A00 mean?
A: H50 stands for 4-20mA with HART, non-explosion-proof type; /K4A00 is the terminal option code for matched FIO terminal assembly.
Q: How many channels does AAI143 have?
A: It has 16 analog input channels, each supporting 4–20mA and HART signal.
Q: Can it work with non-HART 4-20mA transmitters?
A: Yes, it can normally collect standard 4–20mA signals; the HART function will be inactive for ordinary transmitters.
Q: What bus does it use to communicate with FCU?
A: It is FIO type module and communicates with AFV series FCU via ESB bus.
Q: Is this module still available for maintenance replacement?
A: It is a widely used FIO AI card. New surplus and refurbished units are supplied for existing CENTUM VP system spare replacement.
