1、 Product Overview
The TRICONEX AI3351S2 analysis input module is a high-precision analog signal processing unit focused on process industry safety and control scenarios, designed specifically to ensure the safety monitoring and stable control of critical industrial processes. Its core function is to accurately receive analog signals output by various on-site sensors (such as temperature sensors, pressure transmitters, flow meters, liquid level detectors, etc.), and complete filtering, conversion, and verification through built-in signal processing mechanisms, providing reliable data support for subsequent control decisions. This module relies heavily on the core architecture of Triconex's safety and fault-tolerant control system, which not only has industrial grade high reliability, but also incorporates redundancy design concepts to effectively resist single point failure risks. Therefore, it is widely used in industries with strict safety and stability requirements, such as oil and gas extraction and transportation, chemical reaction processes, power production scheduling, and pharmaceutical compliance production. It has become a core signal access component in critical safety control circuits and real-time monitoring systems.
2、 Core technical parameters (typical characteristics)
Product model: AI3351S2
Module type: Industrial grade Analog Input (AI) module, focusing on high-precision acquisition and processing of process signals
Input signal compatibility: Supports multiple types of industrial standard analog signal access (specific signal types can be selected according to actual application configurations), including 4-20 mA current signals (applicable to pressure, flow, and other transmitters), 0-10 V voltage signals (applicable to some liquid level and temperature sensors), thermocouple signals (such as K and J types, used for high temperature environment temperature detection), RTD (resistance temperature detector, such as Pt100, used for high-precision temperature measurement), etc
Signal processing channel: Adopting a multi-channel parallel design, it can independently receive and process multiple sets of analog signals at the same time (the number of channels is determined according to the specific model configuration), with no interference between each channel, meeting the requirements of multi parameter synchronous monitoring
Signal acquisition resolution: Equipped with a high-precision A/D (Analog to Digital) conversion chip, the conversion resolution reaches 16 bits or more, which can accurately capture small changes in analog signals, ensure the accuracy of signal processing and data reliability, and avoid monitoring errors caused by insufficient resolution
Electrical isolation design: Electrical isolation technology (usually photoelectric isolation or electromagnetic isolation) is used between the input channel and the system backplane bus to effectively block external interference signals from entering the module core circuit through the bus, while preventing internal module faults from affecting other components of the system, significantly improving the ability to resist electromagnetic interference and operational stability
Data communication method: High speed data exchange is achieved through the dedicated backplane bus of the Triconex system and the core processing unit of the Tricon controller, with low communication delay, ensuring that the collected signals can be quickly transmitted to the controller for logical operations and control decisions
Security protection mechanism: integrates multiple protection functions, including overcurrent protection, channel isolation protection, signal self diagnosis (real-time monitoring of whether the signal is normal, such as open circuit, short circuit, overtravel, etc.), to comprehensively ensure the safety of the module and system
