Product Name:

TRICONEX 3720 – Analog Input Module

Product Description:

The TRICONEX 3720 module is an analog input module that is part of the Tricon safety system. It provides a critical interface for safely handling analog signals (such as temperature, pressure, flow, and level) and converting them into a format that the Tricon safety system can process. This module ensures that the system receives accurate and reliable analog signals, which are essential for critical safety functions in industries such as oil and gas, chemical, nuclear, and power generation.
