Triconex 3510 Pulse Input Module 8-Channel Speed Sensing

Description

The Triconex 3510 is a high-speed pulse input module for the Trident safety system. It is specifically designed to sense frequency and pulse signals from rotating equipment, such as turbines and compressors, to provide precise speed monitoring within a Triple Modular Redundant (TMR) architecture.
