Digital Input Signals
The standard PreciseFlex 100 robot provides four general purpose optically isolated digital input
and output signals at the X-axis end cap (in addition to those signals that are available at the
Gripper Control Board).
The input signals can be configured as "sinking" (Figure 4-15 and Figure 4-17) or "sourcing"(Figure
4-16 and Figure 4-18). If an input signal is configured as "sinking," the external equipment must pull
its input high to 5VDC to 24VDC to indicate a logical high value or must allow it to float to no voltage
for a logical low. These four inputs are configured at the factory as “sinking.”
