APPLICATIONS

The modules convert and isolate
signals generated by thermocouples
type J (FeCuNi) or K (NiCrNi) into
an analog signal; can be set into 8
temperature input ranges, and can
be set for up to 3 most important
analog ranges. The set up is
possible by setting a dip-witch on
one side of the module.
The modules provide input and
output isolation, assuring high signal
accuracy, and can be used with
isolated and not isolated sensors.
