Product Description:

The TRICONEX 3720 module is a redundant analog input module from Triconex that converts analog signals to digital signals and provides a triple redundancy design to ensure system security. The module has the following features:

High reliability: With triple redundancy design, each channel is executed by three independent A/D converters and processors, and real-time comparison and voting ensure that even if one of the channels fails, the system can operate properly and prevent dangerous accidents.
High precision: Provides high precision data acquisition to meet the accuracy requirements of various industrial applications.
Fast response: with a fast response speed, it can reflect the change of the analog quantity in time.
Easy to use: Provides intuitive configuration interface and rich diagnostic tools, easy to install, configure, use, and maintain.
