Industrial Control Interface and PLC-5 Integration
The 1771-OC provides DC sourcing output switching for PLC-5 control architectures. Its rack-mounted design supports installation within compatible 1771 I/O chassis assemblies. The module uses backplane communication for output data transfer and supports BDC or Natural Binary data formats.
The module follows Allen-Bradley PLC-5 I/O density scaling principles by providing multiple discrete output points in a single rack position. Firmware compatibility and controller configuration must match the selected PLC-5 hardware revision for correct module recognition and operation.
Frequently Asked Questions
Q: What type of field signals can the 1771-OC control?
A: The 1771-OC provides 8 sourcing DC output channels designed for switching DC loads within the specified voltage and current limits.
Q: What is the backplane current requirement of the 1771-OC?
A: The module requires 165 mA from the 1771 chassis backplane supply.
Q: Does the module include electrical protection features?
A: The module includes opto-electrical isolation, conformal coating, and ESD immunity specifications for electrical noise and discharge protection.
Field Installation Guidelines
Install the 1771-OC module only in compatible 1771 I/O chassis positions according to PLC-5 system configuration requirements. Verify output wiring polarity before connecting field devices because the module operates as a sourcing DC output device.
Use the specified 1771-WH wiring arm for field termination. Route DC output wiring separately from high-voltage AC conductors and high-noise signal cables. Maintain proper cabinet grounding practices, and connect cable shields according to the system grounding design.
Confirm the load current requirements of connected solenoids, relays, lamps, or other DC devices before energizing the outputs. Avoid exceeding individual channel and total module current ratings.
