TRICONEX AI3351 is an analog input module widely used in industrial automation and safety control systems.The following is a detailed introduction to the module:
1.Product Overview
TRICONEX AI3351 module is a high-performance analog input module produced by Triconex(now a brand of Invensys).It is designed to receive and process analog signals from sensors,such as temperature,pressure,flow,etc.,and convert these signals into digital signals for processing and decision-making by the control system.
2.Main specifications and parameters
Input signal:
Rated input current:4~20mA.
Input bandwidth(3dB):16Hz.
Pulse input module(AI3351 type)Number of input signals:8,non-shared.
Input frequency range:20Hz~20000Hz(can operate at frequencies below 20Hz or above 20000Hz,but the accuracy and sensitivity need to consult Triconex field service engineers).
Accuracy:±0.01%at 1000~20000Hz,±0.1%at 100~999Hz,±1.0%at 20~99Hz.
Electrical parameters:
Working current range:2~22mA DC.
Power supply voltage:Usually 220V or 280V(determined according to the product specification).
Source impedance:unknown(but other relevant electrical parameters are provided).
Physical parameters:
Weight:1.5 kg(product itself),3 kg(including transport packaging).
Status indicator:1 for each point,module status includes PASS,FAULT,ACTIVE.

III.System features and functions
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:
Field installable,the module level can be installed and repaired online on site without affecting the field wiring.
Module Expandability:
Supports up to 118 I/O modules(analog and digital)and optional communication modules.
Remote Communication Capability:
Communication modules can connect 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.
Remote I/O Support:
Remote I/O modules can be supported up to 12 kilometers from the host.
Windows NT-based Programming:
Develop and debug control programs using Windows NT-based programming software.
Intelligent Functions:
Intelligent functions in input and output modules reduce the workload of the main processor.Each input/output module has three microprocessors.
Comprehensive Online Diagnostics:
Routine maintenance can be performed while the Tricon is operating normally without interrupting the control process.
Hot Standby Support:
“Hot Standby”support is provided for I/O modules for emergency situations where service cannot be provided in a timely manner.
