Compact 1769-OF4CI Isolated Analog Output Module Module Installation Compact I/O is suitable for use in an industrial environment when installed in accordance with these instructions. Prevent Electrostatic Discharge ATTENTION: Electrostatic discharge can damage integrated circuits or semiconductors if you touch bus connector pins or the terminal block. Follow these guidelines when you handle the module: • • • • • • Touch a grounded object to discharge static potential.
Compact 1769-OF4CI Isolated Analog Output Module 7 System Assembly The module can be attached to the controller or an adjacent I/O module before or after mounting. • For mounting instructions, see Panel Mounting on page 10, or DIN Rail Mounting on page 11. • To work with a system that is already mounted, see Replacing a Single Module Within a System on page 11. The following procedure shows you how to assemble the Compact I/O system.
Compact 1769-OF4CI Isolated Analog Output Module 3. Use the upper and lower tongue-and-groove slots (1) to secure the modules together (or to a controller). 4. Move the module back along the tongue-and-groove slots until the bus connectors (2) line up with each other. 5. Push the bus lever back slightly to clear the positioning tab (3). Use your fingers or a small screwdriver. 6. To allow communication between the controller and module, move the bus lever fully to the left (4) until it clicks.
Compact 1769-OF4CI Isolated Analog Output Module 9 Minimum Spacing Maintain spacing from enclosure walls, wireways, adjacent equipment, etc. Allow 50 mm (2 in.) of space on all sides for adequate ventilation.
Compact 1769-OF4CI Isolated Analog Output Module Panel Mounting Mount the module to a panel using two screws per module. Use M4 or #8 panhead screws. Mounting screws are required on every 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.).
Compact 1769-OF4CI Isolated Analog Output Module 11 6. Attach the modules to the panel by 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-OF4CI 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-OF4CI 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-OF4CI 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-OF4CI 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-OF4CI 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.
Compact 1769-OF4CI Isolated Analog Output Module 17 Wire Size and Terminal Screw Torque Each terminal accepts up to two wires with the following restrictions: Wire Type Wire Size Terminal Screw Torque Retaining Screw Torque Cu-90 °C (194°F) #14…#22 AWG 0.68 N•m (6 in•lbs) 0.46 N•m (4.1 in-•bs) Stranded Cu-90 °C (194°F) #16…#22 AWG 0.68 N•m (6 in•lbs) 0.46 N•m (4.
Compact 1769-OF4CI Isolated Analog Output Module Input Data File Word For each module, slot x, input data file words 2…5 contain the state of the module’s output data (output data echo) file words 0…3. During normal operation, these input words represent the analog values that the outputs are directed to by the control program.
Compact 1769-OF4CI Isolated Analog Output Module 19 Configuration Data File The manipulation of the bits from this file is normally done with programming software (for example, RSLogix 500 software or RSNetworx for DeviceNet software) during initial configuration of the system. In that case, graphical screens are provided by the programmer to simplify configuration.
Compact 1769-OF4CI Isolated Analog Output Module Channel Configuration Words The first two words of each eight word group in the configuration file allow you to change the parameters of each channel independently. For example, words 8 and 9 correspond to channel 1 while words 16 and 17 correspond to channel 3.
