Triconex 3531E 115 VAC/VDC Simplex Digital Input Module
Thirty-two discrete inputs on a Simplex module architecture
SECTION 01
Product Overview
The Triconex 3531E is a 32-point Simplex digital input module for the Tricon controller family. It accepts 115 VAC or VDC field states and presents those discrete inputs to the controller through a single module channel rather than a triple-modular-redundant input structure.
Across the complete 3531E, thirty-two input positions form the module's discrete signal capacity. The 115 VAC/VDC designation applies to this input set, while the Simplex designation identifies the single-channel module architecture used to pass those field states into the controller.
Selection of the 3531E depends on all three identifiers together: Simplex architecture, 115 VAC/VDC input level and 32-point capacity. These characteristics distinguish the module without assigning interfaces, diagnostic cycles or compatibility that are not confirmed for this exact catalog number.

SECTION 03
Simplex Digital Input Function
The 3531E brings thirty-two 115 VAC/VDC field states into the controller through a single-channel input-module architecture.
Thirty-two-point capacity
One module collects thirty-two separate input circuits for controller use.
Single-channel architecture
The Simplex designation differentiates this input path from TMR digital-input module construction.
SECTION 04
Input Voltage and Module Scope
The 3531E combines one confirmed electrical level, one module architecture and one point count in the complete product definition.
AC or DC field state
The input designation covers 115 VAC or 115 VDC discrete states on the module's input circuits.
Complete-module capacity
The thirty-two-point value describes the complete 3531E rather than one channel group or a separate termination assembly.
Model-bound electrical level
The 115 VAC/VDC designation belongs to this complete model and should remain visible in wiring and quotation records.
SECTION 05
Frequently Asked Questions
What type of input module is Triconex 3531E?
It is a Simplex digital input module. The module accepts discrete field states rather than analog values. The Simplex designation should remain visible because it defines the module architecture for this exact catalog number.
How many points are provided by Triconex 3531E?
The 3531E provides 32 digital input points. That point count applies to the complete module. The value is the module total and should not be reported as thirty-two points per group or per processor channel.
What field voltage is associated with Triconex 3531E?
Its listed input level is 115 VAC/VDC. Both the voltage and AC/DC designation belong to the exact model description. The electrical value should be preserved as VAC/VDC rather than shortened to an unqualified 115 V entry.
Does Triconex 3531E accept both AC and DC input states?
Yes. The complete product description assigns 115 VAC/VDC to the module, so the electrical designation includes both forms. The field circuit must still follow the exact 3531E termination information rather than an assumed generic AC/DC connection.
Is Triconex 3531E a TMR input module?
No. The exact product description identifies 3531E as Simplex; TMR behavior should not be transferred from a different digital-input model. Selection records should not add voting, self-test or hot-spare behavior that is not confirmed for 3531E.
Can another 35xx wiring diagram be assumed for Triconex 3531E?
No. The confirmed 3531E identity establishes its Simplex architecture, 115 VAC/VDC input and 32-point capacity, but does not make another model's termination diagram applicable. Only a wiring document that explicitly identifies 3531E should be treated as the termination reference for this module.

MOORE AUTOMATION
https://www.mvme.cn/Moore Automation provides enquiry coordination for automation modules whose exact suffix and electrical description must remain attached to the request. For 3531E, the commercial record retains the Simplex, 115 VAC/VDC and 32-point identifiers instead of inferring TMR features from nearby model numbers.
