TRICONEX 3721

The TRICONEX 3721 module is an analog input module manufactured by Honeywell under the TRICONEX brand. It is mainly used in the safety instrument system (SIS), responsible for collecting the analog signal of the field instrument and converting it into a digital signal to provide reliable input data for the safety instrument system.

Product description

The 3721 module is usually installed in the TRICONEX safety instrumentation system and together with other modules (e.g. processor module, output module) constitutes a complete safety system. The module has the characteristics of high reliability and high availability, and is widely used in petrochemical, electric power, nuclear power and other industries to protect personnel, equipment and the environment.
