Product Overview
The Triconex 3510 Pulse Input Module is a safety-certified input card designed to interface with pulse-generating field devices—such as speed sensors, encoders, and flow meters—and provide high-integrity pulse data to a Triconex safety and process control system. It supports eight non-commoned pulse inputs, delivers precise frequency measurements, and integrates advanced diagnostics to ensure reliable operation in industrial and safety-critical environments. The module uses AC-coupled, balanced differential inputs and TMR (Triple Modular Redundant) architecture inherent in the Triconex platform to enhance measurement accuracy and fault detection.
