CURS100 100 Ohm Current Shunt

Terminal Input Module

1. Introduction

Terminal input modules connect directly to the datalogger’s input terminals to

provide completion resistors for resistive bridge measurements, voltage

dividers, and precision current shunts. The CURS100 converts a current signal

(for example, 4 to 20 mA) to a voltage that is measured by the datalogger. The

100 ohm resistor used for the current shunt allows currents up to 25 mA to be

read on a ±2500 mV range (CR10, CR10X) and currents up to 50 mA to be

read on a ±5000 mV range (CR800, CR850, CR1000, CR3000, CR5000,

CR9000X, CR9000, 21X, CR23X).
