These general purpose digital outputs can source up to 625 mA of current. They
can be used to drive equipment like electromagnetic relays directly or for
communication with other PLC systems.
D) Analog Inputs
There are two non-differential, single ended analog inputs on the base I/O, able
to measure a signal in current (4 - 20 mA) or voltage mode (0 - 10 V). The mode
can be specified through Choreograph, or via API calls.
These inputs could, for example, be used to monitor the output of an analog
position sensor, detecting if an object ready for picking. The robot and the
sensor should share a common ground, to ensure all signals are referenced to
the same level.
