TRICONEX 3721

The Triconex 3721 module is an important component of the Triconex Safety Instrumentation System (SIS), which is used to capture analog signals such as temperature, pressure, flow, etc., and convert them into digital signals for processing and analysis by the SIS. It provides high reliability, high precision and high availability analog input functions, and is widely used in safety instrumentation systems in petrochemical, electric power and other fields.

Main function

Analog signal acquisition: Acquisition of analog signals from field instruments, such as 4-20mA current signals or 0-10V voltage signals.
Signal conversion: The conversion of analog signals to digital signals for processing by the safety instrumentation system.
Fault diagnosis: With self-diagnosis function, can detect the fault inside the module.
Redundant design: Adopts redundant design to improve system reliability.
Product parameters and specifications (part)
The specific parameter specifications will vary depending on the configuration and version, the following are some possible parameters:

Number of input channels: Usually multiple, depending on the model of the module.
Input signal type: 4-20mA current signal or 0-10V voltage signal.
