Connecting Inputs to the PCI-7390
Limit, home, inhibit-in (alarm), in-position, and general-purpose inputs are
optically isolated sinking or sourcing inputs. Figures 4-13, 4-14, 4-15,
and 4-16 show a simplified schematic diagram of the circuit used by these
inputs. You can connect these inputs to a current sourcing output device
such as a PNP sensor, as shown in Figure 4-13, a sinking output device
such as an NPN sensor, as shown in Figure 4-14, a high-side switch, as
shown in Figure 4-15, or a low-side switch, as shown in Figure 4-16.
