TRICONEX 3351 Analog Input Module

Description

The TRICONEX 3351 module is an analog input module designed specifically for industrial safety control, widely used in high-risk industries such as power, petroleum, and chemical to ensure the safe operation of factories and facilities. The following is a detailed introduction to the TRICONEX 3351 module:

1、 Basic product information
Manufacturer: Triconex
Product number: 3351
Product type: Analog input module
Nominal input current: 4-20mA
Points: 32 (normal)
Working current range: 2-22 mA DC
Input bandwidth (3dB): 16 Hz
Source impedance: 180 Ω
Weight: 1.5 kilograms (transportation weight may vary)
2、 Technical characteristics
High fault tolerance:
The third mock examination redundant structure (TMR) is provided, which has three identical sub circuits. Each sub circuit performs independent control, and can withstand harsh industrial environment.
Supports up to 118 I/O modules (analog and digital) and optional communication modules, ensuring high reliability and flexibility of the system.
On site installation and maintenance:
It can be installed on-site and module level can be installed and repaired online without interfering with on-site wiring.

Provide comprehensive online diagnostic and repair capabilities, allowing for daily maintenance during startup and operation without interrupting the control process.
Communication capability:
The communication module can be connected to Modbus hosts and slave devices, or to Foxboro and Honeywell distributed control systems (DCS), as well as external hosts in TCP/IP networks.
Support other Tricons in peer-to-peer networks to achieve comprehensive secure communication.
Intelligent functions:
The intelligent functions in the input and output modules can reduce the workload of the main processor.
Each I/O module has three microprocessors, and the output module microprocessor provides information for the voting of output data. The validity of the output status is checked through the feedback loop voltage at the output end, and field line problems can be diagnosed.
Security and reliability:
Specially designed for industrial safety control, capable of executing critical safety logic to ensure the safety of process operations.
Provide “hot standby” support, which can be used in emergency situations where services cannot be provided in a timely manner.
3、 Application field
The TRICONEX 3351 module can be widely used in modern industrial fields such as electricity, petroleum, mine lifting, ports, heating, gas, water supply, sewage treatment, metallurgy, papermaking, textile, chemical, water conservancy, etc.

4、 Summary
The TRICONEX 3351 module plays an important role in the field of industrial safety control due to its high fault tolerance, convenient on-site installation and maintenance, powerful communication capabilities, intelligent functions, and high security and reliability. Whether in harsh industrial environments or in application scenarios that require high reliability and safety, the TRICONEX 3351 module can provide reliable support and assurance.
