Page 3: Product Overview
PRODUCT OVERVIEW The QE-CURRENT-485 is a current transducer (and analyzer in the -H version) capable of interfacing with various isolated current transducers, with both current and voltage outputs, also suitable for reading 2- or 3-wire PT100 or NTC temperature probes, as well as non-characterized probes by entering the STEINHART-HART curve in the Q-WIZARD configuration software. -
Page 4: Inputs
In addition, the digital output can also be associated with an alarm on the input measurement reported at the output; depending on the configuration software setting, the output contact can be set as NC or NO.
