Description
The APD 41393 accepts a thermocouple temperature input and
provides two independent DC process outputs. This makes it
useful to split, isolate, and transmit a thermocouple signal for
measurement, data recording, or validation.
The thermocouple input type and temperature range are fac-
tory set. The two DC output types and ranges are factory set.
The DC outputs can be different and both correspond to the
input temperature range specified. Use appropriate thermo-
couple extension wire for the input 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 the two DC outputs.
Output Sink/Source Versatility
The APD 41393 includes a 20 VDC loop excitation supply for
any channel ordered with a mA output. A mA output can be
selectively wired for sinking or sourcing allowing use with a
powered or unpowered milliamp device.
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.
LoopTrackers
An API exclusive feature includes a green LoopTracker LED
that varies in intensity with changes in the input signal and
red LoopTracker LEDs that vary in intensity with changes in
the DC output signals. 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 output test switches for each
DC output to provide a fixed output (independent of the input)
when pressed. The output test greatly aids in saving time dur-
ing 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.
