PLC-5 Deterministic Output Switching Characteristics
The 1771-OR operates within the Allen-Bradley PLC-5 1771 I/O architecture and transfers output commands through the chassis backplane interface. The module provides six isolated AC output points for controlling 220 VAC field loads with defined current handling capability per channel.
The module design supports PLC-5 I/O density scaling by integrating multiple AC switching channels into a single rack-mounted unit. The conformal coating protects internal electronic assemblies from environmental exposure, while isolated output circuits provide separation between field-side AC loads and the PLC control interface.

Field Installation Guidelines
Install the 1771-OR module in a compatible PLC-5 1771 I/O chassis using the correct rack position and 1771-WH wiring arm. Verify the AC supply characteristics and field device ratings before connecting output circuits.
Use AC-rated wiring methods and maintain separation between output wiring and sensitive signal cables. Apply grounding practices according to the control panel design standard and avoid routing AC output conductors with low-level analog or communication wiring.
Confirm output channel allocation and connected load current requirements before energizing the module. Ensure that individual channel and total module current limits are maintained during operation.
