Wiring Input Devices to the 1746-NI8
After the analog input module is properly installed in the chassis, follow the wiring
procedure below using Belden 8761 cable.
To wire your 1746-NI8 module follow these steps.
1. At each end of the cable, strip some casing to expose the individual wires.
2. Trim the signal wires to 50 mm (2 inch) lengths. Strip about 5 mm (3/16 inch) of
insulation away to expose the end of the wire.
3. At one end of the cable, twist the drain wire and foil shield together. This end of
the cable is connected to one of the shield terminals on the 1746-NI8 module.
Connect shields for channels 0 through 3 to the upper shield terminal and shields
for channels 4 through 7 to the lower shield terminal.
4. At the other end of the cable, cut the drain wire and foil shield back to the cable.
5. Connect the signal wires and shield drain wire to the 1746-NI8 terminal block or
interposing terminal block.
6. Connect the other end of the cable to the voltage or current transmitter terminals.
7. Repeat steps 1 through 6 for each channel on the module.

ATTENTION
Care should be taken to avoid connecting a voltage source to a
current input module. Improper module operation or damage to
the voltage source can occur.

Preliminary Operating Considerations
Publication 1746Ć6.8 - April 1997
The 1746-NI8 analog input module has multiclass interface
capabilities. Class 1 is the standard configuration. The module can
be configured through the user program for Class 3 which enables
user-defined data scaling and monitoring of channel status words.
