connector and to Table 9 for the corresponding signals for each pin. Refer to Figures 24 through 29 for
information on how to wire the digital inputs and outputs on the UMI-7774/72.
You can wire a Digital Input to a sourcing output device, such as a PNP sensor, as shown in Figure 24,
or to a high-side switch as shown in Figure 28. You can use the isolated power (V
iso
) and isolated
common (C
iso
) signals on the control connector to power on the sensor.
