Figure 4-5. Typical User Wiring for XIO Input Signals
NOTE:The OFF state current range exceeds the leakage current of XIO outputs. This
guarantees that the inputs will not be turned on by the leakage current from the
outputs. This is useful in situations where the outputs are looped-back to the inputs
for monitoring purposes.
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, shorted load protection, and is current
limiting. 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 Table 4-5).
Optionally, use the XIO Termination Block. See the documentation supplied with the
termination block for details.
