Technical Information
There are three digital outputs on the I/O board.
Digital Outputs 1 and 2 are 24VDC open collector (sinking logic). They are
rated 25 mA maximum.
Figure 11 -
is an example of how Digital Outputs 1 and 2
would be used with a light.
Note: The transistor in the diagram is the internal circuitry of the Digital
Output. When the logic for Digital Output 1 becomes true, the transistor turns
on, tying the transistor's collector to ground and completing the circuit. Then the
light will turn on.

Digital Output 3 is a relay output rated for 24VDC. The relay output is rated 5 A
at 24VDC for a resistive load, and 2 A at 24VDC for an inductive load.
