ControlLogix Backplane Power Conversion Characteristics
The 1756-PA50 provides AC-to-DC conversion for ControlLogix chassis backplane power distribution. The module supplies regulated 5.1 VDC and 3.3 VDC outputs for connected controllers, communication modules, and I/O modules installed in the chassis.
For Allen-Bradley ControlLogix platforms, the power supply module supports chassis power loading through defined backplane current capacity. The design includes voltage failure indication functions for system shutdown coordination and firmware-controlled monitoring functions.
Frequently Asked Questions
Q: What input voltage range does the 1756-PA50 support?
A: The module accepts 85-265 VAC input with a 47-63 Hz operating frequency range.
Q: What DC outputs are provided by the power supply?
A: The module provides 5.1 VDC output at up to 8 A and 3.3 VDC output at up to 2 A for ControlLogix chassis power distribution.
Q: What chassis mounting configuration is required?
A: The 1756-PA50 is installed as a chassis-mounted ControlLogix power supply module.
Field Installation Guidelines
Install the 1756-PA50 in the designated ControlLogix chassis power supply position and verify that the chassis grounding system is connected according to installation requirements.
Connect AC input wiring using appropriate industrial electrical protection and isolation practices. Keep AC power wiring separated from low-level signal wiring and communication cables. Confirm input voltage compatibility before energizing the module.
Ensure adequate cabinet airflow around the power supply to maintain the specified operating temperature range. Inspect power connections and chassis mounting hardware during maintenance activities.
