2562/2568 PRT Scanner Module

This section explains the features and operation of the optional 2562/2568 PRT
Scanner Module.
9.1

Description

The 2562/2568 PRT Scanner Module is an add-on module that allows the 1560
to measure temperature with up to eight SPRT, PRT, and RTD sensors. The
modules accept two-, three-, or four-wire sensors with nominal resistance of 25
and 100Ω (2562) or 500 and 1KΩ (2568). The excitation current alternates po-
larity to minimize the effects of thermoelectric offsets. Up to eight sensors can
be connected to the 2562/2568 simultaneously and measured alternately.
