PLC-5 Backplane Power Architecture
The 1771-P6S/B provides regulated 5 VDC output through the Bulletin 1771 chassis backplane interface. The module accepts a 220 VAC input supply and distributes DC power to PLC processors, I/O modules, and communication modules installed in compatible chassis configurations.
The module supports parallel connection with compatible power supplies through 1771-CT cabling for increased current capacity. Internal functions include AC input conversion, output voltage regulation, isolation protection, and shutdown signaling when AC input voltage falls below operating limits.
Frequently Asked Questions
Q: What AC input range is supported by the 1771-P6S/B?
A: The module operates from a nominal 220 VAC input with an allowable range of 194-264 VAC at 47-63 Hz.
Q: What backplane output does the 1771-P6S/B provide?
A: The module provides regulated 5 VDC output with up to 8 A current capacity for the Bulletin 1771 chassis backplane.
Q: Can the 1771-P6S/B operate in a parallel power configuration?
A: Yes. The module supports parallel operation with compatible power supplies using 1771-CT cabling for increased current capacity.
Field Installation Guidelines
Install the 1771-P6S/B in a compatible Bulletin 1771 chassis slot and verify AC input voltage before energizing the module. Ensure the installed fuse rating matches the specified protection requirement.
Route AC power wiring separately from low-level I/O and communication cables to reduce electrical interference. Maintain chassis grounding connections according to industrial control panel practices and terminate cable shields using appropriate grounding methods.
When using parallel supply arrangements, verify supply compatibility, cable connections, and total backplane current demand before startup. Maintain sufficient airflow around the module to keep operation within the specified temperature range.
