Sourcing and Sinking
All inputs on the Oak Board can be configured in banks of 4 for sourcing or sinking operation. Whether you will use sinking or
sourcing depends on your devices. The inputs can use 5, 12 or 24 VDC, be sure to install the appropriate SIP resistor. The inputs
are arranged in groups of four with a common shared by each input in a group.
•
Sourcing:
Connecting the inputs to power is sourcing. The negative lead of the power supply must be connected to
common. This is demonstrated on inputs 13-16 in Figure 5.2.3.
•
Sinking:
Connecting the inputs to ground is sinking. The positive lead of the power supply must be connected to
common. This is demonstrated on inputs 9-12 in Figure 5.2.3.
