3.Functions and features

High-precision signal acquisition and processing:TRICONEX 3351 is designed for high-precision signal acquisition and processing to ensure the accuracy of measurement results,suitable for precision process control.

High fault tolerance:Provides a three-module redundant structure(TMR)with three identical sub-circuits,each of which performs a certain degree of independent control and can withstand harsh industrial environments.

Field installable and online maintenance:The module level can be installed and repaired online on site without affecting the field wiring,which improves the availability and flexibility of the system.

Modular design:Supports up to 118 I/O modules(analog and digital)and optional communication modules to facilitate system expansion and upgrade.

Remote communication capability:The communication module can be connected to Modbus masters and slaves,or to Foxboro and Honeywell distributed control systems(DCS),other Tricons in peer-to-peer networks,and external hosts in TCP/IP networks to achieve remote communication and data exchange.

Intelligent functions:Intelligent functions in input and output modules reduce the workload of the main processor and improve the overall performance of the system.

Comprehensive online diagnostics:Routine maintenance can be performed when the Tricon is operating normally without interrupting the control process,which improves the reliability and stability of the system.

Hot standby support:Provides”hot standby”support for I/O modules,which can be used in emergency situations where services cannot be provided in time to ensure continuous operation of the system.
