Yokogawa AAI543-H50/K4A00 16-channel Analog Output Module
Product Brief Description
Yokogawa AAI543-H50/K4A00 is a 16-channel isolated analog output module for CENTUM VP FIO I/O system. It outputs 4–20mA control signals and supports HART communication. The -H50 means HART-enabled, standard switchover redundant version, non-explosion-proof; /K4A00 stands for KS cable adapter option matched with AEA4D terminal block. It receives control commands from FCU and drives field control valves, positioners and HART smart actuators via ESB bus.
Product Functions
- Output isolated 4–20mA analog control signals to field control valves and actuators
- Support HART communication for remote valve parameter setup and device diagnostics
- 16 channels with field-to-system isolation, withstand voltage 1500V AC for 1 minute
- Open-circuit detection to alarm broken wiring on output loops
- Receive control setpoints from AFV FCU and transmit status data over ESB bus
- Support dual redundant module configuration with standard switchover response
- Front LED indicators for run, communication and channel fault status, support hot swap
Application Scenarios
- Petrochemical, refinery and natural gas plant CENTUM VP DCS control loops
- Thermal power and combined cycle units for feedwater, steam and fuel valve regulation
- Chemical, pharmaceutical and water treatment continuous process control
- FIO I/O cabinets for HART valve positioners and modulating actuator control
- DCS cabinet renovation, spare replacement and system expansion projects
FAQ
Q: What do H50 and /K4A00 mean?
A: H = HART function, 5 = standard switchover redundancy, 0 = basic non-explosion-proof; /K4A00 is ATK4A KS adapter option to connect AEA4D terminal board.
Q: What is the difference between AAI543 and AAI143?
A: AAI543 is analog output module for valve control; AAI143 is analog input module for collecting 4-20mA transmitter signals.
Q: What is the allowable load resistance?
A: 0 to 750Ω, suitable for most common 4-20mA valve positioners.
Q: Which bus does it use?
A: It is FIO I/O module, communicates with AFV series FCU through ESB bus.
Q: Is this module available for spare replacement?
A: It is a common FIO AO card. New surplus and refurbished units are supplied for maintenance of existing CENTUM VP DCS systems.
