APPLICATIONS
The modules convert and isolate
signals generated by 3 wire / 2 wire
PT100 (RTD) sensors into analog
signals; the module can be set into
8 temperature ranges and for up to
3 most important analog ranges.
Set up is easily achieved by setting
a dip-switch 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.
Two wire sensors can be used by
connecting a jumper wire between
1 and 4 terminal blocks.
