Product Description
Product Overview
The Triconex Pulse Input Module P13381 is designed to capture and process high-frequency pulse signals generated by rotating equipment. It provides accurate speed and frequency measurements from magnetic and electronic speed sensors, supporting reliable monitoring of turbines, compressors, pumps, and other critical machinery.
This module converts pulse transitions into precise rotational data, which is forwarded to Tricon main processors for safety logic execution. Its design emphasizes signal integrity, noise immunity, and deterministic performance in safety-critical applications.
Functional Capabilities
The Triconex P13381 supports six independent pulse input channels, each capable of handling both amplified and non-amplified sensor signals. Using a gear-tracking measurement algorithm, the module calculates speed by analyzing pulse count and timing, ensuring stable readings across a wide operating range.
Channel isolation and configurable termination options allow the module to adapt to varying field wiring conditions while maintaining measurement accuracy and electrical protection.
