PLC-5 I/O Deterministic Output Control Characteristics
The 1771-OGD/B operates within the Allen-Bradley PLC-5 1771 I/O architecture and receives output commands through the chassis backplane interface. The module provides I/O density scaling through 16 sourcing output points in a single rack-mounted unit, allowing multiple DC field loads to be controlled from PLC logic execution.
The output circuitry uses optical isolation and individual current limiting to separate field-side switching conditions from the PLC control interface. The module supports PLC-5 firmware flash compatibility considerations by maintaining the standard 1771 I/O communication structure and hardware addressing method used by the platform.
Frequently Asked Questions
Q: What type of field devices can be connected to the 1771-OGD/B outputs?

Q: How many output points are available on the module?
A: The 1771-OGD/B provides 16 sourcing DC output channels.
Q: What backplane power requirement is specified for the module?
A: The module requires 300 mA from the 5 VDC PLC-5 backplane supply.
Field Installation Guidelines
Install the 1771-OGD/B module in a compatible PLC-5 1771 I/O chassis using the correct slot configuration and wiring arm connection. Verify that field supply voltage matches the connected DC load requirements before energizing outputs.
Use appropriate field wiring practices for DC switching circuits. Separate output wiring from high-voltage AC conductors and high-frequency switching cables to reduce electrical interference. Connect cable shields according to the site grounding method where shielded wiring is applied.
Confirm output channel assignments, load current requirements, and polarity before connecting external devices. Ensure that connected loads remain within the specified per-channel and total module current limits.
