Description

The APD 41390 accepts a thermocouple temperature input and
provides two independent thermocouple outputs. This makes
it useful to match up the available thermocouple type with
AC resistive
an instrument T/C input, for data recording, or when isolating
load
inputs and outputs.
The thermocouple types are factory set. Both output tempera-
tures correspond to the input temperature and are limited by
the smallest ANSI temperature range of the three T/C types you
select. Each T/C type may be different if desired. Use appropri-
ate thermocouple extension wire as needed.
The input is sampled, CJC compensated, digitally converted to
30 50 100 300 500
a linearized temperature signal, and then passed to the output
stages where it is converted to two simulated thermocouple
outputs with CJC compensation. Contact factory if the CJC
compensation is to be disabled.

Note: Temperature range is limited by the smallest ANSI
range of the three T/C types selected.
Full 4-way galvanic isolation (input, output 1, output 2, power)
make this module useful for ground loop elimination, common
mode signal rejection, and noise pickup reduction.
LoopTracker
An API exclusive feature includes a green LoopTracker LED that
varies in intensity with changes in the process input signal.
It provides a quick visual picture of your process input at all
times and can greatly aid in saving time during initial startup
and troubleshooting.
