Sinking Output: 0V when active Sourcing Output: +24V when active
Active Low Input: 0V when activated Active High Input: +24V when activated
Fanuc robots use the following output methods
Process I/O: Sink Output
Terminal I/O: Source Output
Model A I/O: Source Output
I/O Explanation
The terms sinking and sourcing define the direction of DC current flow in a load.
A sinking output provides a path to 0V for the load. Common terms used to describe sinking devices
include NPN, Open Collector, Active Low and IEC Negative Logic. An active low input is connected to
the positive supply (+24V) to detect a sinking output.
A sourcing output provides the power to the load. Common terms used to describe sourcing devices
include PNP, Open Emitter, Active High and IEC Positive Logic. An active high input is connected to 0V
to detect a sourcing output.
Factory set options: Active high robot input. Sinking robot output.
