2、 Technical specifications
Power supply: 24VDC
Number of channels: 8
Signal range: 4~20mA
Rated input current: 4~20mA
Working current range: 2~22mA DC
Input bandwidth (3dB): 16Hz
Input frequency range: 20Hz~20000Hz (can operate at frequencies below 20Hz or above 20000Hz, but accuracy and sensitivity require consultation with Triconex on-site service engineers)
Accuracy: ± 0.01% at 1000-20000Hz, ± 0.1% at 100-999Hz, ± 1.0% at 20-99Hz
Input diagnostic fault range: 0.5% of the full range
Input change sampling period: one scan or 210 milliseconds, whichever is longer
Weight: 1.5 kilograms (product itself), 3 kilograms (including transportation packaging, also known as weighing 3kg)
Dimensions: may vary depending on different suppliers or product batches, such as 267 (W) × 107 (H) × 302 (D) mm or 4.5 × 18.8 × 21.7cm
Points: 32 points (shared, for analog input module 3351 type)
Status indicator: 1 per point, module status includes PASS, FAILT, ACTION
3、 System characteristics and functions
High fault tolerance: Three module redundant structure (TMR) is provided, with three identical sub circuits. Each circuit performs independent control to a certain extent, and can withstand harsh industrial environment.
On site installation: Module level can be installed and maintained online on site without affecting on-site wiring.
Module Scalability: Supports up to 118 I/O modules (analog and digital) and optional communication modules.
Remote communication capability: The communication module can be connected to Modbus hosts 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.
Support remote I/O: It can support remote I/O modules up to 12 kilometers away from the host.
Programming based on Windows NT: Develop and debug control programs using programming software based on the Windows NT system.
Intelligent functions: The intelligent functions in the input and output modules reduce the workload of the main processor. Each input/output module has three microprocessors.
Comprehensive online diagnosis: Routine maintenance can be performed during normal operation of Tricon without interrupting the control process.
Hot standby support: Provides "hot standby" support for I/O modules, which can be used in emergency situations where services cannot be provided in a timely manner.
4、 Application scope
The TRICONEX AI3351 analog input module is widely used in industrial fields that require high reliability and safety, such as power, oil, mine lifting, ports, heating, gas, water supply, sewage treatment, metallurgy, papermaking, textiles, chemical industry, water conservancy and other modern industrial fields. As part of the Tricon control system, this module is able to meet the high requirements of these industries for safety instrumented systems, ensuring the safe operation of factories and facilities.
