The Triconex  3721 module is an analog input module primarily used to convert analog signals from field devices, such as temperature, pressure, flow, etc., into digital signals for processing by the Triconex Safety Instrumented System (SIS). This module is widely used in industrial automation and control systems, especially in scenarios that require high-precision data acquisition and real-time monitoring, such as industries such as petrochemicals, power, steel, pharmaceuticals, etc.

The TRICONEX 3721 module has the following main features and technical specifications:

High precision: Provides 0.1% FS or higher accuracy.
Multi channel: typically with 4, 8, or 16 channels, supporting multiple analog input types such as 4-20mA, 0-10V, etc.
Redundancy design: Adopting redundancy design to ensure high reliability and availability of the system.
Environmental adaptability: able to withstand harsh environmental conditions such as extreme temperatures, impacts, and vibrations.
Communication protocol: Supports multiple communication protocols such as Modbus, Profibus DP, HART, etc.
Working temperature range: Wide range of working temperatures, from -40 ℃ to 70 ℃.
Size and weight: The standard size is 120mm x 80mm x 40mm, and the weight is approximately 500g.
The TRICONEX 3721 module is widely used in key control applications in industries such as oil and gas, petrochemicals, power generation, chemicals, and water and wastewater treatment. It is used to monitor and control various process variables to ensure the safety of production processes. In addition, it is also used to achieve data exchange and integration between devices to meet the needs of different industries.
