NI-DCPower (English | Japanese)

Short Name: Output Connected

Property of niDCPower

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.

Note  This property is not supported by all devices. Refer to Supported Properties by Device for information about supported devices.

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 NI PXI-4132 or NI PXIe-4138/39.

Default Value: Refer to Supported Properties by Device for the default value by device.
