CURS100 100 Ohm Current Shunt

Terminal Input Module

Introduction

NOTE

Terminal input modules connect directly to the data logger 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 data logger. The

100-ohm resistor used for the current shunt allows currents up to 50 mA to be

read on a ±5000 mV range (CR6, CR800, CR850, CR1000, CR1000X,

CR3000, CR5000, CR9000X, CR9000). The CR300 allows currents up to

25 mA with a –100 to +2500 mV range.

The CR6 (serial numbers greater than or equal to 7502),

CR300-series, and CR1000X dataloggers are able to do current

measurements directly. While compatible with the CURS100, the

CURS100 is not required to convert the current signal to a voltage.

CurrentSE() instruction.
