Output Channels and Signal Configuration
The 1769-OF4VI converts controller output data into analog voltage signals for connected control devices. Its four differential output channels support several voltage ranges.Configure each channel according to the receiving device’s signal requirements and the controller program.
Individual channel isolation helps separate the output circuits electrically. The module also provides overrange and underrange status reporting, allowing the controller program to monitor output conditions.
Wiring and Installation Considerations
Each channel uses positive and negative voltage output terminals. The module wiring diagram also identifies an earth-ground connection and terminals marked N/C. Therefore, follow the terminal assignments and grounding instructions for this exact module when preparing field wiring.
The module uses a removable terminal block, which supports wiring maintenance without requiring the individual field conductors to be permanently attached to the module body. Verify the terminal block configuration and replacement door part number before ordering service parts.
Frequently Asked Questions
Q: Is the 1769-OF4VI a current output module?
A: No. The 1769-OF4VI is an analog voltage output module. It supports four individually isolated differential voltage outputs, while the 1769-OF4CI is the corresponding isolated analog current output model.
Q: Which voltage ranges does the 1769-OF4VI support?
A: The supported ranges are +/-10 VDC, 0-10 VDC, 0-5 VDC, and 1-5 VDC. Select the appropriate range based on the connected device and the channel configuration.
Q: Can the terminal block or module door be replaced?
A: The supplied information identifies a removable terminal block and replacement door part number 1769-RD. Confirm the required component and its physical compatibility before ordering.
