The Allen-Bradley 1771-P10 is a DC-powered rack-mounted power supply module designed for use within the 1771 I/O chassis ecosystem. It accepts a 125 VDC external input and delivers a regulated 5 VDC output current of up to 8 A to the system backplane. This 2-slot module features built-in self-monitoring and a controlled soft-start capability to protect connected automation hardware.

Power Specification and Operation

The module operates from an external 125 VDC power source with an acceptable operating range of 97 to 145 VDC. It provides up to 8 A of backplane output current at 5 VDC to support system logic and I/O modules. For applications requiring higher current capacity, two 1771-P10 power supplies can be connected in parallel using a 1771-CT paralleling cable to deliver a combined total of 16 A.

Installation and Protection Features

Occupying two physical slots in a 1771 series A or B I/O chassis, the power supply includes a front-panel status indicator (P/S ACTIVE) for real-time diagnostic monitoring of overvoltage, undervoltage, and overcurrent conditions. Internal protection is reinforced by a replaceable 1.5 A, 250 V slow-blow input fuse. It also incorporates a soft-start function to minimize transient states during power-up cycles.

Frequently Asked Questions

Q: Can the 1771-P10 power supply be operated in parallel for system redundancy?

A: No. While two 1771-P10 units can be paralleled using a 1771-CT cable to double the total available backplane current to 16 A, this configuration increases power capacity rather than providing electrical redundancy.

Q: Which chassis series are compatible with this power supply module?

A: The 1771-P10 is designed for installation in 1771 series A or B I/O chassis, occupying any two available slots except the leftmost processor slot.
