1756-PB75R Allen-Bradley ControlLogix Redundant Power Supply Module

Product parameters

Electrical specification

Input voltage range: 85-265V AC (47-63Hz) / 125-250V DC (compatible with both AC and DC inputs)

Output power: 75W

Output voltage/current: -5V DC: 13A max (Logic Control power supply)

-24V DC: 2.8A max (Powered by I/O module)

Efficiency: ≥85% (typical value)

Surge current protection: ≤20A (during cold start)

Protection and Reliability

Overcurrent protection

Overvoltage protection

Short-circuit protection

Overheat protection

The redundant switching time is ≤20ms

Environmental adaptability

Operating temperature range: 0°C to +60°C (32°F to +140°F)

Storage temperature range: -40°C to +85°C (-40°F to +185°F)

Humidity range: 5-95% RH (non-condensing)

Protection grade: IP20 (Needs to be installed in the ControlLogix chassis)

Function

Hot-swappable redundancy support: Supports online replacement (hot-swappable), no need to stop the machine during maintenance.

AC/DC dual input compatibility: Supports both AC (85-265V AC) and DC (125-250V DC) inputs simultaneously, suitable for unstable power grids or DC battery backup scenarios.

ControlLogix system integration: Monitor the power status (voltage, temperature, load) through backplane communication and integrate diagnostic functions (alarms can be viewed through Studio 5000).

Compatible with all ControlLogix cases.

LED status indication

Green RUN light: Normal operation

Red FAULT light: Overload/short circuit/overheating fault

Yellow REPLACE light: Power module life warning

Application scenarios

Key process control: Industries such as petrochemicals, pharmaceuticals, and power systems that require 24/7 continuous operation.

High availability manufacturing: Scenarios such as automotive production lines and semiconductor equipment that have a "zero tolerance" for downtime.

Unstable power grid environment: Remote mining areas, old factories and other places with large voltage fluctuations.

Extended system power supply: Large ControlLogix racks (such as 17-slot chassis) are paired with 1756-PA75 standard power supplies to share the load.
