Description:
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.
Wiring the Finger-Safe Terminal Block
When wiring the terminal block, keep the finger-safe cover in place.
1. Loosen the terminal screws to be wired.
2. Route the wire under the terminal pressure plate. You can use the bare
wire or a spade lug. The terminals will accept a 6.35 mm (0.25 in.) spade
lug.
3. Tighten the terminal screw making sure the pressure plate secures the
wire. Recommended torque when tightening terminal screws is 0.68 Nm
(6 in-lbs).
NOTE The terminal screws are non-captive. Therefore, it is
possible to use a ring lug [maximum 1/4 inch o.d. with a
0.139 inch minimum i.d. (M3.5)] with the module.
NOTE If you need to remove the finger-safe cover, insert a screw
driver into one of the square, wiring holes and gently pry
the cover off. If you wire the terminal block with the
finger-safe cover removed, you will not be able to put it
back on the terminal block because the wires will be in the
way
