Invensys Triconex PI3381 Module

TRICONEX PI3381 features:
Data processing: It has certain data processing capabilities, can perform simple calculations and data storage, helps to analyze and process the collected industrial data, and provides support for control decisions.
Communication interface: It supports multiple communication protocols, facilitates data exchange with other devices or systems, and can effectively transmit and interact with sensors, actuators, host computers and other devices on site.
Input/output expansion: More input/output points can be added through expansion modules to meet the control needs of different scales, and can flexibly adapt to the point requirements of various complex industrial automation control systems.
Status indication: It has a status indicator that can display the on or off status of each point, as well as the status of the module, such as passing, failure, and activation. It can also provide on-site alarm functions to facilitate operators to understand the working status of the module in real time.

 

Other Parameters:
Load/Fuse Point Isolation: 1000VDC
Maximum Output Toggle Rate: Enables proper operation of I/O diagnostics and detection of all normally detectable faults
Minimum Output Toggle Rate: Provides fault coverage for normally undetectable faults within 10% of the calculated module MTBF, plus one scan every 100ms
Diagnostic Fault Duration: 2ms, maximum on-voltage drop typical at 250mA on backplane, with external termination, 10ft cable, and 99ft cable with external termination

 

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-ofthree 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 from the field, while analog inputs are subject to a mid-value selection process.

 

Because each channel is isolated from the others, no single-point failure in any channel can pass to another. If a hardware failure does occur on one channel, the other channels override it. Meanwhile the faulting module can easily be removed and replaced while the controller is online without interrupting the process.

 

Setting up control programs is simplified with the triplicated Tricon system, because it operates as a single control system from the user's point of view. The user terminates sensors and actuators at a single wiring terminal and programs the Tricon with one set of control program logic. The Tricon controller manages the rest!

 

Extensive diagnostics on each channel, module, and functional circuit immediately detect and report operational faults by means of indicators or alarms.
