External Power Switch
The 1769-OF8V has an external 24V dc power switch which 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 to 26.4V dc and 125 mA
minimum.
