EtherNet/IP and ControlLogix Redundant Power Architecture
The 1756-PA75R/A provides regulated DC power through the ControlLogix backplane interface while supporting redundant power supply arrangements. The module enables I/O density scaling by maintaining chassis power availability for controllers, communication modules, and I/O modules. The redundant architecture allows system designers to configure multiple power sources for continued chassis operation during individual supply faults.
Backplane Bus Communication and Firmware Compatibility
The 1756-PA75R/A functions as a power hardware component within the ControlLogix platform and does not perform user application processing or network communication. System compatibility is determined by chassis configuration, installed modules, and backplane power requirements. The module integrates with ControlLogix systems through the standard backplane bus structure.
Frequently Asked Questions
Q: What is the purpose of the redundancy function in the 1756-PA75R/A?
A: The module supports redundant power supply configurations where multiple power supply units can be arranged to maintain chassis power availability during a supply fault condition.
Q: What DC output levels are provided by the 1756-PA75R/A?
A: The module provides 5.1 VDC and 3.3 VDC outputs for ControlLogix chassis backplane power requirements.
Q: Is the 1756-PA75R/A a communication module?
A: No. The module provides AC power conversion and backplane power distribution only. Communication functions are provided by separate ControlLogix communication modules.
Field Installation Guidelines
Install the 1756-PA75R/A in the designated ControlLogix chassis power supply location and verify redundant supply configuration requirements before operation. Confirm AC input wiring matches the specified voltage range and apply appropriate protective grounding.
Route AC power cables separately from low-level analog wiring and communication network cables to reduce electromagnetic interference. Verify chassis mounting, backplane engagement, and environmental conditions before energizing the system. For redundant installations, confirm both power supply units are correctly connected and configured according to system design requirements.
