SCXI-1314T TEDS Bridge Sensor Terminal Block
❑
Tools
–
Number 2 Phillips screwdriver
–
Long-nose pliers
–
Wire cutter
–
RJ-50 terminal crimper
❑
Cables and plugs
–
Shielded twisted pair (up to 5 pair, 10 conductor) cable
–
Up to eight RJ-50 (10p10c) modular plugs
Note
If your application does not require shunt calibration, you also can use RJ-45
10 position/8 conductor (10p8c) modular plugs in which only pins 2 through 9 are
populated. However, NI recommends using the RJ-50 (10p10c) for most applications.
Changing the Shunt Resistors
Note
Refer to the
Read Me First: Safety and Radio-Frequency Interference
document
before removing equipment covers or connecting or disconnecting any signal wires.
Each channel input contains pins that connect to the inputs and outputs of
the SCXI-1520, and to a precision 100 k
Ω
shunt calibration resistor. The
SCXI-1520 contains relays that switch the resistors in and out of the input
circuit to provide shunt calibration. These resistors are placed in sockets
on the SCXI-1314T terminal block so you can easily replace them with
resistors suitable to the specific Wheatstone-bridge sensor in your
application. If your application requires different shunt resistor values,
exchange the resistors with the appropriate value 1/4 W resistors.
Note
Only the shunt resistors are socketed.
