TRICONEX 3721

The TRICONEX 3721 module is an analog input module manufactured by Triconex (now acquired by ABB) for use in safety instrumentation systems (SIS). It can convert analog signals from the field (such as temperature, pressure, flow, etc.) into digital signals and transmit them to the safety instrumentation system for monitoring and controlling process variables to ensure the safety of the production process.

Product description
The 3721 module is a highly reliable analog input module with a redundant design for stable operation in harsh industrial environments. It is usually installed in the safety instrument system, and works with other modules to form a complete safety system.

Main function
Analog acquisition: Converts analog signals from the field into digital signals.
Signal processing: The collected signal is filtered, amplified an

d other processing.
Data transmission: The processed data is transmitted to the safety instrumentation system.
Fault diagnosis: With self-diagnosis function, can detect and report faults.
