    Locate the I/O system as close to your sensors or actuators as your application will permit. • Current outputs (Iout 0+ to Iout 7+) of the 1769-OF8C module source current that returns to ANLG COM. Load resistance for a current output channel must remain between 0 and 500 Ω.
  • Page 9 Compact 1769-OF8C Analog Output Module External Power Switch The 1769-OF8C 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.
  • Page 10 Compact 1769-OF8C Analog Output Module Wiring Output Devices Basic wiring of output devices is shown below. • Miswiring of the module to an AC/DC source will damage the ATTENTION module. • Be careful when stripping wires. Wire fragments that fall into a module could cause damage at power up.
  • Page 11 Compact 1769-OF8C Analog Output Module 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 Nm (4.1 in-lbs).

  • Page 13 Compact 1769-OF8C Analog Output Module Input Data File For each module, slot x, input data file words 3-10 contain the state of the module’s output data (output data echo) file words 0-7. During normal operation, these input words represent the analog values that the outputs are directed to by the control program.
  • Page 14 Compact 1769-OF8C Analog Output Module Configuration Data File The manipulation of the bits from this file is normally done with programming software (e.g. RSLogix 500, RSNetworx for DeviceNet, etc.) during initial configuration of the system. In that case, graphical screens are provided by the programmer to simplify configuration.
