Yokogawa AAI143-H00 CENTUM VP 16-Channel Isolated HART Analog Input Module
A sixteen-channel isolated current-input module with HART communication and the H00 basic execution.
Product Identification
AAI143-H00 is a Yokogawa AAI143 current-input module with sixteen isolated 4–20 mA channels and HART communication. It can supply two-wire transmitters or accept four-wire transmitter signals, selected per channel by the module setting pins.
The H00 execution must stay tied to the installed terminal or cable arrangement. A zener barrier is not permitted with this module for intrinsically safe use; Yokogawa directs users to an isolation barrier when that protection method is required.
The H00 suffix identifies the HART-capable basic execution and must match the FCS project and field termination.

Functions
Acquire isolated current signals
Provides sixteen separated 4–20 mA measurement paths.
Power two-wire transmitters
Makes the published transmitter supply available when a channel is configured for two-wire service.
Carry HART data
Supports digital maintenance communication on compatible field-device loops.
Applications
Process transmitter bank
Use for documented two-wire and four-wire 4–20 mA field instruments.
HART maintenance path
Retain device tags, poll addresses and host access records for supported instruments.
Intrinsically safe loop
Use an approved isolation barrier rather than a zener barrier where required.
Lifecycle
Inventory
Record AAI143-H00, FCS slot, termination route, transmitter type and HART device identity.
Configure
Retain each channel’s two-wire/four-wire setting, range, damping and engineering scaling.
Replace
Follow the approved node and loop isolation process while preserving shields and polarity.
Validate
Check known current values, HART access, diagnostics and alarms for every active channel.

FAQ
Does AAI143-H00 support HART communication?
Yes. Yokogawa lists HART communication as available for the AAI143 module.
Can a zener barrier be connected to AAI143-H00?
No. Yokogawa states that an isolation barrier must be used when an intrinsically safe barrier is required.
What should accompany a AAI143-H00 request?
Provide the H00 label, termination type, channel list, two-/four-wire settings and HART device records.
Why do channel setting pins matter on AAI143-H00?
They select the two-wire or four-wire transmitter arrangement individually for each channel.
How should AAI143-H00 be accepted?
Verify current accuracy with a known source and confirm HART communication, diagnostics and scaling on used channels.
