TRICONEX 4351B is a high-performance industrial control module launched by Honeywell’s TRICONEX brand.It is designed for critical control and safety applications and is widely used in industries with high reliability requirements such as petroleum,chemical,electric power,and transportation.The following are its core features and application scenarios.

TRICONEX 4351B

Core functions and features

High reliability and fault-tolerant design

Adopting a three-module redundant(TMR)architecture,three independent processors run synchronously.When a single module fails,the system can continue to run,ensuring the safety and continuity of critical processes.

Support hot-swap function,and the faulty module can be replaced without interrupting system operation.

Flexible communication capabilities

Provide 4 serial ports and 2 Ethernet ports,support multiple communication protocols such as Modbus,TCP/IP,OPC,etc.,and can be seamlessly integrated with TriStation,Tricon,Modbus devices,etc.

Support alias configuration function,which facilitates Modbus devices to read and write Tricon variables.

Powerful input and output capabilities

Equipped with 16 digital output channels,each channel supports 24V DC,1A drive capability,suitable for high-precision digital signal control.

Supports a variety of analog and digital input types,with high resolution and accuracy,and can monitor and process complex signals in real time.

Comprehensive safety and diagnostic functions

Built-in fault detection and diagnostic mechanisms to monitor communication faults in real time and generate alarms.

Provides power distribution,redundancy,monitoring,hot swapping,overload protection and other functions to ensure stable system operation.

Programming and compatibility

Supports programmable functions,and users can write control logic and safety rules according to their needs.

Compatible with other TRICONEX products and systems(such as TRICON,TRIDENT),easy to integrate and expand.

TRICONEX 4351B

Application scenarios

Oil and gas:used for automated control of production,transportation and processing processes to ensure equipment safety and efficiency.

Chemical and pharmaceutical:monitor and control chemical reactions,mixing,separation and other processes to ensure product quality and factory safety.

Power industry:used for monitoring power generation and transmission processes to ensure system reliability and stability.

Transportation:control and monitor traffic lights,road signs and other facilities to maintain traffic safety.

Building automation:provide reliable power supply and signal control for smart building and office building control systems.

Technical Parameters

Power supply:supports multiple power supply voltages and configurations to adapt to different industrial environments.

Temperature range:operating temperature is-40°C to 70°C,suitable for harsh environments.

Protection level:the housing is rated for use in hazardous areas,ensuring safety in flammable and explosive environments.
