Compact 1769-OF4VI Isolated Analog Output Module ATTENTION: Remove power before removing or inserting this module. When you remove or insert a module with power applied, an electrical arc may occur. An electrical arc can cause personal injury or property damage by: • sending an erroneous signal to your system’s field devices, causing unintended machine motion. • causing an explosion in a hazardous environment. Electrical arcing causes excessive wear to contacts on both the module and its mating connector.

Disconnect power. 2. Check that the bus lever of the module to be installed is in the unlocked (fully right) position. 3.
Compact 1769-OF4VI Isolated Analog Output Module 6. To allow communication between the controller and module, move the bus lever fully to the left (4) until it clicks. Make sure it is locked firmly in place. ATTENTION: When attaching I/O modules, it is very important that the bus connectors are securely locked together to ensure proper electrical connection. 7. Attach an end-cap terminator (5) to the last module in the system by using the tongue-and-groove slots as before. 8.

Use M4 or #8 panhead screws. Mounting screws are required on every module.
Compact 1769-OF4VI Isolated Analog Output Module Panel Mounting Using the Dimensional Template Host Controller Spacing for single-wide modules 35mm (1.378 in.) Spacing for one-and-a half-wide modules 52.5mm (2.067 in.) Refer to host controller documentation for this dimension. Note: Overall hole spacing tolerance: ±0.4mm (0.016 in.). 30535-M Panel Mounting Procedure Using Modules as a Template The following procedure lets you use the assembled modules as a template for drilling holes in the panel.
Compact 1769-OF4VI Isolated Analog Output Module 11 6. Attach the modules to the panel using the mounting screws. TIP If mounting more modules, mount only the last one of this group and put the others aside. This reduces remounting time during drilling and tapping of the next group. 7. Repeat steps 1 … 6 for any remaining modules. DIN Rail Mounting The module can be mounted using the following DIN rails. • 35 x 7.5 mm (1.38 x 0.30 in.; EN 50 022 - 35 x 7.5) • 35 x 15 mm (1.38 x 0.59 in.
Compact 1769-OF4VI Isolated Analog Output Module 5. Gently slide the disconnected module forward. If you feel excessive resistance, check that the module has been disconnected from the bus, and that both mounting screws have been removed (or DIN latches opened). TIP It may be necessary to rock the module slightly from front to back to remove it, or, in a panel-mounted system, to loosen the screws of adjacent modules. 6.
Compact 1769-OF4VI Isolated Analog Output Module 13 System Wiring Guidelines Consider the following when wiring your system: • Channels are isolated from each other. • Use Belden 8761, or equivalent, shielded wire. • Under normal conditions, the drain wire and shield junction must be connected to earth ground, via a panel or DIN rail mounting screw at the analog I/O module end. Keep the shield connection to ground as short as possible.
Compact 1769-OF4VI Isolated Analog Output Module Labeling the Terminals A removable, write-on label is provided with the module. Remove the label from the door, mark the identification of each terminal with permanent ink, and slide the label back into the door. Your markings (ID tag) will be visible when the module door is closed.
Compact 1769-OF4VI Isolated Analog Output Module 15 Removing the Finger-safe Terminal Block To remove the terminal block, loosen the upper and lower retaining screws. The terminal block will back away from the module as you remove the screws. When replacing the terminal block, torque the retaining screws to 0.46 N•m (4.1 in•lb).
Compact 1769-OF4VI Isolated Analog Output Module 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. TIP The terminal screws are non-captive. You can use a ring lug [maximum 6.35 mm (0.25 in.) o.d. with a 3.53 mm (0.139 in.) minimum i.d. (M3.
