TRICON 4328 Product Details
TRICON 4328 Introduction
TRICON 4328 is a high-security and high-availability programmable logic controller(PLC)produced by Honeywell(formerly Triconex).It is mainly used in safety instrumented systems(SIS)to monitor and control safety-critical functions in industrial processes.It is widely used in industries such as petrochemicals,power,and nuclear power to ensure the safety and reliability of production processes.
Main Features
High Safety Integrity Level(SIL):TRICON 4328 can meet the highest safety integrity level requirements of SIL 3,ensuring that safety functions can be reliably performed even in extreme situations.
Redundant Design:Triple Modular Redundancy(TMR)design is adopted to improve the fault tolerance and reliability of the system.
Modular Structure:Modular design facilitates system expansion and maintenance.
Rich I/O:Provides a variety of I/O modules to meet different application requirements.
Powerful Diagnostic Function:Built-in powerful self-diagnostic function can detect and handle potential faults in time.
Comply with international standards:Comply with international safety standards such as IEC 61508.
Application areas
