Source:Output Connected

Specifies whether the output relay is connected (closed) or disconnected (open). The Output Enabled property does not change based on this property; they are independent of each other.
Set this property to FALSE to disconnect the output terminal from the output.
Note Only disconnect the output when disconnecting is necessary for your application. For example, a battery connected to the output terminal might discharge unless the relay is disconnected. Excessive connecting and disconnecting of the output can cause premature wear on electromechanical relays, such as those used by the PXIe-4147, PXI-4132, or PXIe-4138/39.
Note The PXIe-4051 does not have an output relay. For the PXIe-4051, this property specifies whether the input MOSFETs are connected (ON) or disconnected (OFF).
Note NI-DCPower uses the terms "source" and "output". However, while sinking with electronic loads and SMUs these correspond to "sinking" and "input", respectively.
Note
This property is not supported by all devices. Refer to
