Installing the Module
Caution
Refer to the
Read Me First: Safety and Radio-Frequency Interference
document
before removing equipment covers or connecting/disconnecting any signal wires.
You can plug the SCC-ACC01 into any analog input socket on the
SC-2345. It can function as a single-stage module or as the first stage of
a dual-stage signal conditioning configuration. The socket you choose
determines which E Series DAQ device channels receive the SCC-ACC01
signals, as explained in the
Connecting the Input Signals
section.
For single-stage input conditioning, plug the SCC-ACC01 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-ACC01 in a dual-stage configuration, the SCC-ACC01
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 the SCC-ACC01 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
is an SCC-ACC01 followed by a lowpass filter module (SCC-LP
XX
).
Although not available for the SCC-ACC01, sockets J9 to J16 are available
for digital input/output conditioning or control with another SCC module.
Refer to the
SC-2345/2350 User Manual
for more information on
configuring, connecting, and installing SCC modules.
Connecting the Input Signals
Note
The signal names have changed. Refer to
ni.com/info
and enter
rdtntg
to
confirm the signal names.
Each screw terminal is labeled by pin number <1..4>. Pins 1 and 2 form a
differential (DIFF) analog input channel for measuring the voltage across
the accelerometer. This channel is routed to E Series DAQ device
channel
X
, where
X
is 0 to 7 depending on the socket where you plug in
the SCC-ACC01. Pins 3 and 4 carry the 4 mA constant-current excitation
source. Figure 1 shows the SCC-ACC01 signal connections.
