Product Description:

Designed to accurately measure resistance, the 3AT350.6 I/O module accepts four inputs for PT100 resistance sensors only. This module includes status indicators that provide information about what the converter is doing and how long it took as well as helping diagnose problems. It uses 3.0 W at 24 VDC and 1.0 W at 5 VDC, totaling 4.0 W while operating electrically; they are not electronically isolated from each other or the PLC.

Its certified to be compliant with industrial control equipment per CE, UKCA, cULus (E115267) standards fulfillment guaranteeing that this module complies with all necessary requirements towards such devices. The built-in digital converter has a resolution of 13,500 steps within the measurement range allowed by three-wire cables (resistance measurement). The format of its output is INT while conversion time can either be given as 85 ms during a period when measurements take place every 16.67 ms or else at 100 ms for events occurring once in every twenty milliseconds but which one happens depends on settings made by the user through the software configuration tool. Connectivity Pack Third Age Technology Ltd offers free downloadable drivers etcetera which give more flexibility here than any other supplier does so far know.

PT100 sensors can be used with this 3AT350.6 module whose baseline accuracy is ~0.1% at 20C over temperature range from -50 to +450C where it achieves highest precision performance among all available options currently accessible worldwide market places today. This makes them the most suitable choice for applications demanding stringent accuracy requirements at extreme temperatures encountered in various sectors including scientific research institutions dealing mainly with cryogenics labs. While operating within such facilities, these modules have been found to perform exceptionally well under severe environmental conditions where these units normally operate properly, at expected levels, thus proving their reliability because they were designed specifically keeping in mind worst-case scenarios often encountered there.
