Yokogawa AAI143-H50/K4A00 16-Channel HART Analog Input Module
A 16-channel 4–20 mA input module with HART communication and the ATK4A-00 KS cable interface adapter.
PRODUCT CONTEXT
Product Profile
AAI143-H50/K4A00 provides sixteen isolated 4–20 mA inputs and supports HART digital communication. Yokogawa decodes H as the HART execution, 5 as no explosion protection, 0 as the basic type and /K4A00 as the supplied ATK4A-00 KS cable interface adapter for an AEA4D terminal board.
The module updates data every 10 ms and permits 2-wire or 4-wire transmitter selection by channel. The complete suffix and option code must remain with the field-termination record.

HART communication
Provides digital communication on the supported field loops while retaining the analog process signal.
Channel wiring selection
Allows the 2-wire or 4-wire transmitter mode to be set for each channel.
Defined KS interface
Uses the /K4A00 adapter to route the module to the documented AEA4D termination.

CUSTOMER QUESTIONS
FAQ
Q01
What does H50/K4A00 identify on AAI143-H50/K4A00?
It identifies HART communication, no explosion protection, the basic execution and the ATK4A-00 KS cable adapter.
Q02
Can a standard AAI143-S50 replace AAI143-H50/K4A00?
Not when the application requires the documented HART communication and /K4A00 termination path.
Q03
What should accompany a AAI143-H50/K4A00 enquiry?
Provide the full H50/K4A00 label, AEA4D and KS cable records, channel list, transmitter modes and quantity.
Q04
Can a Zener barrier be connected directly to AAI143-H50/K4A00?
Yokogawa states that a Zener barrier is not allowed; use an isolation barrier for intrinsically safe applications.
Q05
What proves AAI143-H50/K4A00 is ready after service?
Correct channel values, documented 2-wire or 4-wire modes, HART access and clean diagnostics close the test.
