Data Acquisition / Scanning Systems Use Reed Relays

Introduction

Throughout the industrial world, data acquisition and scanning instruments are used to scan and acquire data from various data collection sensors. These may be in the form of thermocouples, pressure transducers, and an assortment of other types of transducers. For a given requirement, there could be 100s of data points that need to be scanned for data and then stored or displayed. This data once gathered can then be graphed for trends, trip points, or alarm activation. In most cases, reed relays are desirable for the electrical scanning of the signals because generally, the transducers output very small voltages and currents. Maintaining signal integrity is critical for proper measurement.
