PLC-5 Deterministic Output Switching Characteristics
The 1771-OP is designed for Allen-Bradley PLC-5 platforms and exchanges output control data through the 1771 I/O backplane interface. The module provides digital AC switching through four output points configured for 120 VAC field loads.
The module architecture follows PLC-5 I/O density scaling principles by integrating multiple AC switching channels into a single rack-mounted unit. The conformal coating provides protection for internal electronic assemblies against environmental exposure. The output circuitry includes protected switching elements for AC load control applications.

Field Installation Guidelines
Install the 1771-OP module in a compatible PLC-5 1771 I/O chassis using the correct rack position and 1771-WH wiring arm. Verify that the connected AC supply voltage is within the module operating range before applying power.
Use suitable AC-rated field wiring and maintain separation between control wiring and high-voltage conductors where required. Follow site grounding practices for shielded wiring installations and avoid routing signal cables alongside high-noise switching circuits.
Confirm output channel assignments and load current requirements before connecting field devices. Ensure that the total module current and individual output current limits are not exceeded during operation.
