Triconex 3722X Tricon CX Fast Analog Input Module
32-POINT FAST AI
01
Product Summary
For fast 0-5 V DC field measurements, Triconex 3722X is the 32-channel, single-ended TMR analog input module installed in the 8131X Tricon CX I/O expansion chassis. It converts those measurements into voted process values for the control application, and its signal route does not include HART pass-through.
Signals for Triconex 3722X enter through a compatible external termination panel, cross the interface cable and 9769X FET connector, and reach three isolated common-core paths. Each path uses its own converter and multiplexer to sample the same field point; the module then compares those results before updating the value delivered over the three processor I/O-bus paths.
The 9.5 ms update of Triconex 3722X comes from its input-filter and conversion sequence rather than from a separate communication channel. The module front indicators report module, field and individual point conditions, while all transmitter power and permanent field wiring remain on the termination-panel side of the connector chain.

Performance Characteristics - Fast Analog Input
Product-specific focus
3722X prioritizes fast, repeatable analog acquisition without adding a HART communication path.
Measurement precision
Sixteen-bit conversion, stated FSR accuracy and repeatability keep the numeric process value tied to the 0-5 V input range.
TMR comparison
Three internal paths compare the acquired signal before the voted value is delivered to the controller application.
04
System Integration - Non-HART Analog Path
3722X depends on the 8131X chassis and a compatible 9769X termination route for all thirty-two field points.
External termination
Supported ETPs accept the field conductors and present the required voltage signal through the interface cable.
FET transfer
The 9769X connector carries the commoned analog points between external panels and the chassis module position.
Non-HART boundary
Device data cannot be obtained through this module as HART pass-through; a HART requirement changes the module and host path.
05
Questions & Answers
When should 3722X be selected instead of 3723X?
Select it when the application needs the faster 9.5 ms analog update and does not require HART pass-through. The two modules should not be exchanged only because both accept 0-5 V signals.
Does 3722X accept 4-20 mA transmitters?
A compatible termination panel can convert the current loop into the module's 0-5 V input path. Confirm the ETP type and loop power before ordering.
Which connector is used with 3722X?
The 32-point chassis FET is 9769X. The external panel and cable still need to match the number of points and the field wiring method.
What causes measurement error on 3722X?
Check source scaling, termination resistance, loop grounding, shield routing and the configured engineering range. Module accuracy cannot correct an incorrect current-to-voltage conversion.
Can 3722X provide HART device information?
No. It is the fast non-HART analog input. Use a supported HART-capable module and termination path when device communication is required.
Where can 3722X be installed?
It is installed only in the 8131X I/O expansion chassis. The chassis address and logical slot must match the controller project.
