1. Product Title

Red Lion N31HRHL‑LNK‑NS‑04‑ High‑Speed Pulse Input Counter / Rate Meter Module

2. Product Overview

N31HRHL‑LNK‑NS‑04 is a high‑performance process counter and rate meter for industrial pulse‑based measurement applications. It receives high‑frequency pulse signals from flow sensors, encoders and proximity switches, calculating total count, flow rate and speed values. The unit features configurable relay alarm outputs for threshold triggering, and supports data communication for host system data acquisition. No‑display variant focuses on back‑cabinet measurement processing. Rugged circuit design tolerates electrical noise in factory environments, widely used for flow totalization, rotation speed monitoring and production counting in process and manufacturing plants.
