Features

High 5.1 VDC capacity

The 13 A rating at 5.1 VDC supports high backplane loading while the total combined output remains within 75 W.

Multiple backplane rails

The supply provides 1.2, 3.3, 5.1 and 24 VDC outputs directly to the ControlLogix chassis backplane.

Standard chassis format

It mounts on the left side of a compatible 1756-A4, A7, A10, A13 or A17 chassis.

Industrial environmental rating

Published specifications cover 0 to 60 degrees C operation, 5 to 95 percent noncondensing humidity, vibration and shock.

Power Output

Combined output limit	The combined loading of the 1.2, 3.3, 5.1 and 24 VDC backplane outputs must not exceed 75 W.
5.1 VDC rail	Up to 13 A for ControlLogix chassis loads.
3.3 VDC rail	Up to 4 A for supported backplane loads.
1.2 and 24 VDC rails	Up to 1.5 A at 1.2 VDC and 2.8 A at 24 VDC.
Input wiring	Use 2.5 mm2 (14 AWG) solid or stranded copper wire rated 90 degrees C or higher and tighten the conductor screw to 0.565 N m.

Installation

01 - Verify the catalog number

Match 1756-PB75 on the quotation, product label, packaging and Rockwell Automation product record before installation.

02 - Confirm chassis compatibility

Use a compatible Series B or Series C 1756-A4, A7, A10, A13 or A17 chassis for the Series B supply.

03 - Mount the supply

Install the supply on the left side of the chassis with power removed and follow publication 1756-IN619.

04 - Connect 24 VDC input

Use the specified copper conductor, observe polarity and torque, and provide the required external disconnect and protection.

05 - Check the load budget

Calculate the total current on every backplane rail and keep the combined output at or below 75 W.

06 - Remove the protective label

Remove the protective label after wiring and before operation so ventilation is not obstructed.

Environment

Operating temperature

0 to 60 degrees C.

Storage temperature

-40 to +85 degrees C.

Relative humidity

5 to 95 percent, noncondensing.

Mechanical endurance

2 g vibration at 10 to 500 Hz, 30 g operating shock and 50 g nonoperating shock.

Protection

Open-style equipment; install it in a suitable industrial enclosure and observe the applicable hazardous-location instructions.

Hazardous-location marking

The installation publication lists Ex ec IIC T4 Gc protection and ATEX, IECEx and UKEX certificate references for 1756-PB75 when marked.

FAQ

Q1. How can the exact quoted 1756-PB75 be verified?

Match the complete 1756-PB75 catalog number on the quotation, power-supply label and packaging. Confirm the standard 24 VDC input type, 75 W output, 13 A rating at 5.1 VDC, left-side chassis mounting and the required series.

Q2. How can New, Used or Refurbished condition be distinguished?

Request date-marked photos of the complete label, serial and series markings, input terminals, chassis connector, housing, mounting points and packaging. Look for terminal marks, scratched mounting surfaces, altered labels, dust or repair seals.

Q3. How should supplier legality and reliability be checked?

Verify the supplier legal entity, registered address, invoice details, payment beneficiary and traceable contact. The written offer must state Allen-Bradley 1756-PB75, condition, series, quantity and included documentation.

Q4. Which specifications must engineering confirm before purchase?

Confirm the 18 to 32 VDC input range, 24 VDC nominal supply, 75 W combined output limit, 13 A at 5.1 VDC, current on the other backplane rails, Series B or C chassis compatibility, dimensions, weight, wiring and environmental ratings.

Q5. What physical evidence should be requested before payment?

Ask for one date-marked photo set showing the full 1756-PB75 label, serial and series markings, 24 VDC input terminals, chassis connector, mounting hardware, housing condition, protective label and packaging.

Q6. Can 1756-PB72, 1756-PB75K or 1756-PBXT replace 1756-PB75?

Not automatically. 1756-PB72 has a lower 5.1 VDC current rating, 1756-PB75K is the conformal-coated option, and 1756-PBXT is the extended-temperature XT design with different chassis compatibility and output ratings. Verify every rail, series, chassis and environmental requirement before substitution.
