10 Compact™ 1769-OF2 (Series B or Later) Analog Output Module

Publication 1769-IN049A-EN-P

External Power Switch

The 1769-OF2 (Series B or later) 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 in the up position (default), 24V dc power
is drawn from the 1769 system power supply via the 1769 I/O bus. In the
down position, 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 120 mA minimum.

Wiring Output Devices

Basic wiring of output devices is shown below.

ATTENTION

• Miswiring of the module to an AC/DC source will

damage the module.

• Be careful when stripping wires. Wire fragments that

fall into a module could cause damage at power up.
Once wiring is complete, ensure the module is free of
all metal fragments.
