GS4 DC inputs can also be wired for sourcing. In this configuration, notice that the 24VDC supply
is feeding into the DIC (Digital Input Common) terminal and the current is coming out of the drive
input (GS4 is sourcing) and the field device is sinking the current.
GS4 DC outputs can also be wired as sinking or sourcing. A sourcing output supplies current.
This requires a device (pilot light, buzzer, PLC input card) that will sink the current. Notice how
the electronics of the output allow current to flow out the DO1 or DO2 terminal. The DOC (Digital
Output Common) terminal is connected to +24VDC.
The same drive output circuit can be used to sink current. Notice below that the DOC terminal is
now connected to the power supply common. The pilot light sources the current into the drive.
The drive output sinks the current. (Even though the light has 24V on it at all times, it will not light
up unless current is flowing through it and into the drive output).
NOTE: GS4 output can be wired as sinking or sourcing, but not both at the same time.
