Description
The APD 41391 accepts a thermocouple temperature input and
provides one DC process output and one thermocouple output.
This makes it useful to match up the available thermocouple
type with an instrument input type, for data recording, or when
isolating the input.
The thermocouple input type and temperature range are fac-
tory set. The DC output type and range, and the thermocouple
output type and range are factory set. The DC output and the
thermocouple output correspond to the input temperature
AC resistive
range specified. Mixed T/C types are limited by the ANSI
load
temperature range. Use appropriate thermocouple extension
wire as needed.
The input is sampled, CJC compensated, digitally converted to
a linearized temperature signal, and then passed to the output
stages where it is converted to a DC output and a simulated
thermocouple output 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 two T/C types selected.
Full 4-way galvanic isolation (input 1, 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 input signal and a red
LoopTracker LED that varies in intensity with changes in the
channel 1 DC output signal. It provides a quick visual picture
of your process at all times and can greatly aid in saving time
during initial startup and troubleshooting.
Output Push-to-Test
An API exclusive feature includes an output test switch to pro-
vide a fixed output for the DC output channel (independent of
the input) when pressed. The output test greatly aids in saving
time during initial startup and/or troubleshooting.
The output test level is factory set to approximately 75% of
span but a custom test level may be ordered.
