Triconex 3503EN2 digital input module

PRODUCT DETAILS

The Tricon is a state-of-the art controller that provides fault

tolerance by means of Triple-Modular Redundant(TMR)

architecture. TMR integrates three isolated, parallel control

systems and extensive diagnostics in one control system.

The system uses two-out-of-three voting to provide high-integrity,

error-free, uninterrupted process operation with no single

point of failure.
The Tricon controller uses three identical channels. Each

channel independently executes the control program in parallel

with the other two channels.Specialized hardware/software

voting mechanisms qualify and verify all digital inputs and outputs f

rom the field, while analog inputs are subject to a mid-value selection

process
