TRICONEX 4351B is a product of TRICONEX company, and its detailed information is as follows:

essential information:

It is a module in the Triconex Safety Instrumented System (SIS).

Functional features:

Redundancy design: As part of the Triconex system, it usually has a triple redundancy architecture (2oo3 structure, i.e. two out of three voting) to improve system reliability and fault tolerance. A single channel failure does not affect the normal operation and safety functions of the system.

 Signal processing function: The specific function depends on the module type (such as input, output, etc.). If it is an analog input module, it can receive standard analog signals such as 4-20mA, 0-10V, etc. and convert them into digital signals for system processing. It may have functions such as temperature and pressure compensation to improve measurement accuracy; If it is an analog output module, it outputs standard signals such as 4-20mA to drive the load; The digital input/output module processes digital signals, with inputs conforming to standard logic levels and outputs capable of driving loads such as relays.

Application areas: Mainly used in industrial fields such as petrochemicals, refining, natural gas, and electricity that require high safety, safety instrumented systems are used to monitor key process parameters, achieve control and safety protection, such as emergency shutdown systems (ESD), to ensure timely and safe shutdown or take protective measures in case of abnormalities.
