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).
