01 / MODULE PROFILE
 
Built around
mixed analog loops.

AAI841-H50 is an analog I/O module for Yokogawa FIO architecture. The module provides eight analog input channels and eight analog output channels, using 4–20 mA signals and a non-isolated channel structure.

The H suffix adds digital communication using the HART protocol, making the module suitable where analog process loops and digital device communication are required together.

02 / ENGINEERING DETAILS
Configuration Points That Matter
 
HART FUNCTION

The -H suffix denotes the HART communication version of the AAI841 analog I/O module.
 
2 / 4-WIRE

The transmitter connection type can be selected for each channel by setting pin.
 
NON-ISOLATED

AAI841 belongs to the non-isolated analog I/O group, so system wiring conditions must be checked before replacement.
 
HARDWARE MATCH

When replacing a module, verify the complete model and the associated terminal connection arrangement.

 

 

 
03 / SAME FAMILY
AAI841 Series Architecture
 

The AAI841 family uses the same eight-input/eight-output, 4–20 mA, non-isolated analog I/O architecture. The suffix configuration determines communication and environmental options, while option codes can specify the terminal connection arrangement.

05 / BUYER QUESTIONS
AAI841-H50 FAQ
 
Q1 · Does AAI841-H50 provide both analog I/O and HART communication?
Yes. AAI841 provides eight 4–20 mA input channels and eight 4–20 mA output channels, and the -H suffix denotes the version with HART digital communication. The module remains a non-isolated analog I/O configuration.
 
Q2 · What should be checked before replacing an existing AAI841-H50?
Check the complete model code, the FIO configuration, the terminal connection arrangement, the transmitter wiring type, and whether HART communication is required. AAI841 is non-isolated, so the existing system wiring and field interface arrangement should also match.
 
Q3 · Can AAI841-H50 work with both 2-wire and 4-wire transmitters?
The AAI841 family provides channel-level selection for 2-wire or 4-wire transmitter connection by setting pin. For a replacement, the existing field wiring should be checked against the required channel configuration before installation.
 
Q4 · Is AAI841-H50 the same hardware configuration as AAI841-H53?
No. Both belong to the AAI841 family, but the suffixes represent different configurations. H50 is the HART version with no explosion protection and the basic type, while H53 adds the ISA Standard G3 option and the wider temperature option. The complete suffix should therefore be checked when selecting a replacement.
 
Q5 · What terminal arrangement should be confirmed when ordering AAI841-H50?
The base AAI841-H50 can be paired with different connection arrangements through option codes such as /K4A00, /A4S00, /A4S10, /A4D00, /A4D10 and /CCC01. If the existing installation uses a specific terminal board or cable interface, the complete order code should be provided for configuration matching.
