PLC-5 Backplane Power Distribution
The 1771-P5 provides regulated 5 VDC power through the Bulletin 1771 chassis backplane interface. The module accepts a 24 VDC input supply and distributes DC power for PLC processors, I/O modules, and communication modules installed in compatible chassis configurations.
The power supply module supports parallel connection with compatible units through 1771-CT cabling for increased current capacity. The design includes input voltage monitoring, output regulation, isolation circuitry, and shutdown signaling when input conditions fall outside operating limits.
Frequently Asked Questions
Q: What input voltage is required for the 1771-P5?
A: The module operates from a 24 VDC input source with an allowable input range of 20.5-30 VDC.
Q: How much backplane current can the 1771-P5 provide?
A: The module provides up to 8 A at 5 VDC for Bulletin 1771 chassis backplane power.
Q: How many chassis slots does the 1771-P5 occupy?
A: The module occupies two adjacent slots in a compatible 1771 I/O chassis.
Field Installation Guidelines
Install the 1771-P5 in the specified two-slot position of a compatible Bulletin 1771 chassis. Verify DC input polarity and voltage range before connecting field power wiring.
Use appropriate conductor sizing for DC input connections and maintain separation between power wiring and low-level I/O signal cables. Connect chassis grounding according to industrial control panel practices and ensure shielded signal cable drain wires are terminated according to system grounding requirements.
When using parallel power supply configurations, confirm cable compatibility, supply matching, and total backplane current demand before energizing the chassis. Maintain airflow around the module to support operation within the specified temperature range.
