XIO Output Signals
The eight digital outputs share a common, high side (sourcing) Driver IC. The Driver is
designed to supply any kind of load with one side connected to ground. It is designed for
a range of user-provided voltages from 10 to 24 VDC and each channel is capable of up to
0.7 A of current. This Driver has overtemperature protection, current limiting, and
shorted-load protection. In the event of an output short or other overcurrent situation, the
affected output of the Driver IC turns off and back on automatically to reduce the
temperature of the IC. The Driver draws power from the primary 24 VDC input to the
robot through a self-resetting polyfuse.
The outputs are accessed through direct connection to the XIO connector (see Tab le 4 -5
on page 43), or through the optional XIO Termination Block. See the documentation
supplied with the XIO Termination Block for details.
