Product Description

TRICON 3721 is a high-performance analog input module manufactured by Triconex (now a Schneider Electric brand) for use in industrial automation and process control systems. Below are the details of its products:
Product overview
The TRICON 3721 is a 4-channel analog input module with triple modular redundancy (TMR) architecture that significantly improves system reliability and security. The module asynchronously measures input signals through three separate channels and passes the results to the main processor module, providing high availability and security.
Product characteristics
Triple redundancy: Each I/O module contains three independent sub-circuits, so that even if any channel or component fails, the system can continue to operate.
High precision measurement: Support 0 to 5 VDC or -5 to +5 VDC input range, resolution up to 16 bits.
Fast update rate: The input update rate is 10 milliseconds.
Intrinsically safe certification: Suitable for hazardous areas to ensure safe operation in harsh environments.
Fail-safe operation: In the event of a failure, the system can automatically switch to the safe state.
Diagnostic function: Provides diagnostic functions to help quickly identify and resolve problems and reduce maintenance costs.

Product parameter

Input channels: 32 differential inputs, DC coupled.
Input range: 0 to 5 VDC or -5 to +5 VDC.
Resolution: 12 or 16 bits.
Operating temperature: 0°C to 55°C.
Mounting method: DIN rail mounting.

Application field

TRICON 3721 is widely used in the following areas:
Petrochemical: Used for temperature, pressure, flow and other parameters monitoring and control.
Power industry: Used for monitoring and regulating the operating parameters of generator sets.
Pharmaceutical industry: Used in the process of drug production temperature, stirring speed, material flow and other parameters monitoring.
Metallurgical industry: Used for temperature, composition and other parameters monitoring.
Other industrial applications: such as paper, textile, machinery manufacturing, etc.
