TRICONEX 3721

Description

TRICONEX 3721 is a device widely used in the field of industrial automation and process control.The specific information is as follows:

I.Product Overview

TRICONEX 3721 is a digital control module or communication module produced by Honeywell.It supports Ethernet supply host chassis and can connect other devices to realize data communication and control functions.This module is usually used in safety-critical applications,such as automation control systems in industries such as oil,gas,chemicals,power and water treatment.

II.Main functions and features

Digital input function:

When used as a digital input card,TRICONEX 3721 provides 16 digital input channels that can be used to monitor various types of digital signals.

Each channel is individually configurable,allowing users to set input type,filter,de-jitter time and other parameters.

Supports a variety of digital input types,including contact closure,voltage signal and current signal.

Analog input function:

When used as an analog input module,TRICONEX 3721 provides 32 channels of analog input,supports differential 0~5 volts or-5 to+5 volts input signals,and ensures high accuracy of signal acquisition.

TRICONEX 3721

Adopt triple-mode redundant(TMR)design to improve system availability and meet SIL3 functional safety requirements.

Support programmable configuration with 12-bit or 14-bit resolution and 10 millisecond sampling rate to meet different accuracy requirements and fast response needs.

Communication and connection:

Support Ethernet communication to facilitate data exchange with other devices and systems.

Can be used to connect the main chassis and other devices,such as I/O modules,to achieve system expansion and integration.

High reliability and safety:

TRICONEX 3721 adopts high-quality materials and manufacturing processes,with high pressure resistance,corrosion resistance and other properties.

Designed for harsh environments,it can withstand extreme temperatures,shocks and vibrations.

Through self-diagnosis and redundant design,ensure that the system can maintain high safety and reliability in various environments.

Easy to install and configure:

TRICONEX 3721 is hot-swappable and can be replaced without interrupting system operation.

It can be configured using Triconex’s TriStation 1131 software,which provides a user-friendly interface for configuring and monitoring Triconex systems.

3.Application fields

TRICONEX 3721 is widely used in industrial automation fields with extremely high safety requirements,such as petrochemical,electric power,nuclear power,etc.It is used to measure process variables such as temperature,pressure,flow,etc.to achieve process control and safety protection.At the same time,the module is also suitable for scenarios that require remote monitoring and operation,and remote access to equipment and systems can be achieved through the communication module.
