PXI-4110 Pinout

The following figures show the terminals on the PXI-4110 output connector and auxiliary power input connector.

Output Connector

Figure 4. PXI-4110 Output Connector Pinout


Table 4. Output Connector Signal Descriptions
Signal Name Description
CH <0> +6 V (0 V to +6 V) HI force terminal connected to channel power stage (generates and/or dissipates power). Positive polarity is defined as voltage measured on HI > LO.
CH <0> GND LO force terminal connected to channel power stage (generates and/or dissipates power) and internally tied to chassis ground. Positive polarity is defined as voltage measured on HI > LO.
CH <1> +20 V (0 V to +20 V) HI force terminal connected to channel power stage (generates and/or dissipates power). Positive polarity is defined as voltage measured on HI > LO.
CH <1..2> Isolated GND LO force terminal connected to channel power stage (generates and/or dissipates power). Positive polarity is defined as voltage measured on HI > LO.
CH <2> -20 V (0 V to -20 V) HI force terminal connected to channel power stage (generates and/or dissipates power). Positive polarity is defined as voltage measured on HI > LO.

Auxiliary Power Input Connector

Table 5. Auxiliary Power Input Signal Descriptions
Signal Name Description
Terminal 0 + An optional terminal that, if provided with 11 V to 15.5 V and ≥60 W, increases the output current capability of channels 1 and 2 to 1 A.
Terminal 1 - This terminal provides the return current path to the aux power supply; internally connected to chassis ground.
