FloBoss 107 Instruction Manual
4-16 Inputs and Outputs Revised June-2017
DO functions include:

Sustained discrete outputs.

Momentary discrete outputs.

Toggled output.

Time duration output.
The discrete output channel is a normally-open, FET switch. The discrete
output is a solid-state switch enabled by individual signals from the
processor I/O lines and capable of handling 50 Volts dc at 0.2 A
maximum.
You configure the DO so that after a reset the DO retains the last value or
switches off. When a request is made to change the state of a DO, the
request is immediately sent to the DO. There is no scan time associated
with a change of DO.
If the DO is in momentary or toggle mode, you can enter a minimum
time-on of 50 milliseconds (.05 seconds).
Notes:

Select DO as the I/O Type for the selectable analog output/discrete
output when you configure it for use as a discrete output. Refer to
Figure 4-5 .

When using the discrete output to drive an inductive load (such as a
relay coil), place a suppression diode across the load. This protects the
DO from the reverse Electro-Motive Force (EMF) spike generated
when the inductive load is switched off.
4.10.1 Wiring the Discrete Outputs
The terminals for connecting the DO wiring on the CPU module are
shown in
Figures 4-13 and 4-14 . The “+” terminal is the high side of the
switch and the “–” terminal is the low side.
Caution
You can induce ground loops by tying commons from various modules
together.
