Publication 1746-IN006A-US-P
Wiring Single-Ended Inputs
The following diagram shows typical wiring for the 1746-NI8 module.
• Use shielded communication cable (Belden™ 8761) and keep length as short as
possible.
• Connect only one end of the cable shield to earth ground.
• Connect the shield drain wires for channels 0 to 3 to the top shield terminal.
• Shield terminals are internally connected to chassis ground which is connected to
earth ground via the SLC backplane.
• Single-ended source commons may be jumpered together at the terminal block.
• Channels are not isolated from each other.
• If a different signal source has an analog common, it cannot and must not be
connected to the module.
• Common mode voltage range is ±10.5 volts. The voltage between any two
terminals must be less than 15 volts.
• The module does not provide power for the analog inputs.
• Use a power supply that matches the transmitter (sensor) specifications.
IMPORTANT
Follow these guidelines when wiring the module.
