External Power Switch
The modules have an external 24V DC power switch that gives you the option
of using an external power supply. The switch is located in on the lower left
portion of the module’s circuit board, as shown below. With this switch pressed
on the top (default), 24V DC power is drawn from the 1769 system power
supply via the 1769 I/O bus. Pressed on the bottom, 24V DC power is drawn
from the external power supply.
Wire the external power supply to the module via the module’s terminal block.
The external power supply must be rated Class 2, with a 24V DC range of
20.4…26.4V DC and the following minimums:
• Volatge 135 mA
• Current 185mA
