Installing the Output and AUX I/O Connector on the PXIe-4150

Complete the following steps to install the output connector assembly with a module and prepare signal connections.
  1. Ensure the AC power source is connected to the chassis.
    Note The AC power cord grounds the chassis and protects it from electrical damage.
  2. Power off the chassis.
  3. Touch any metal part of the chassis to discharge static electricity.
  4. Slide the accessory plug into the corresponding jack on the front panel of the module until it is fully inserted.

Signal Name Description
HI HI force terminal connected to channel power stage (generates and/or dissipates power). Positive polarity is defined as voltage measured on HI > LO.
LO LO force terminal connected to channel power stage (generates and/or dissipates power). Positive polarity is defined as voltage measured on HI > LO.
HI Sense Voltage remote sense input terminals. Used to compensate for I x R voltage drops in cable leads, connectors, and switches.
LO Sense
Shield GND Chassis grounding.

Signal Name Description
GND Ground reference for AUX I/O.
PFI <0 , 1 , 2> Programmable Function Interface for digital timing and triggering.
FAULT Device fault status output.
INHIBIT Forces the PXIe-4150 output to an inhibited state when not shorted to ground. You can short this pin to ground using the pre-installed jumper to enable normal operation.
