SCC-TC Series Thermocouple Input Modules User Guide 4 ni.com
A blue stripe on the label identifies the SCC-TC0X as an analog input
module. The label also displays the icon shown in Figure 1.

You can plug the SCC-TC0X into any analog input socket on the SC-2345.
The socket you select determines which E Series DAQ device channels
receive the SCC-TC0X signals.
For single-stage input conditioning, plug the SCC-TC0X into any socket J
(X +1), where X is 0 to 7, and connect the input signals to the module as
described in the Connecting the Input Signals section.
If you use the SCC-TC0X in a dual-stage configuration, the SCC-TC0X
must be the first-stage module. Plug it into any socket J (X+9) and plug the
second-stage SCC into socket J (X+1), where X is 0 to 7. Connect the input
signals to SCC-TC0X as described in the Connecting the Input Signals
section. The SC-2345 connects the output signals of the first-stage SCC to
the inputs of the second-stage SCC. An example of dual-stage conditioning
in an SCC-TC0X followed by an SCC-LP01 lowpass filter module.
Sockets J9 to J16 also are available for digital input/output (DIO)
conditioning or control. Refer to the SC-2345 User Manual for more
information on configuring, connecting and installing SCC modules
Note SCC-TC0X dual-stage configuration is only available in NI-DAQ 7.1 or later.
Connecting the Input Signals
The SCC-TC01 has a two-prong uncompensated thermocouple
miniconnector that accepts any miniature or subminiature two-prong
male thermocouple connector. The SCC-TC02 has a three-position
screw-terminal connector that accepts 28 to 16 AWG thermocouple wires.
The screw-terminal connector provides a ground connection for shielded
thermocouples. Otherwise, the two modules function identically.
To use an SCC-TC01, plug the male thermocouple connector into the
module.
