Description

Allen-Bradley 1756-PAR2 is a ControlLogix redundant AC power supply bundle. The package contains paired redundant supplies, power cables and a chassis adapter. Each supply accepts a wide AC input range. The adapter routes power to the ControlLogix chassis backplane. Individual supply ratings apply to the redundant arrangement and must not be added together as a combined power rating.

This ControlLogix power supply kit supports installations where maintaining chassis power is an operational priority. The redundant arrangement provides an alternative power path when a supply becomes unavailable. Status signaling helps maintenance staff identify a supply condition. Review the chassis generation and adapter arrangement before replacement. Check the complete kit contents against the equipment already installed.

Applications

System integration

1756-PAR2 serves ControlLogix control panels that require redundant chassis power. Continuous-process machinery can use the paired supply arrangement to support the controller and its chassis-based modules. The annunciator connection makes supply status available to the control system.

Maintenance planning

In plant maintenance projects, 1756-PAR2 provides a coordinated supply, cable and adapter package. Check the existing chassis and power distribution before ordering. The bundle is intended for a redundant architecture rather than an ordinary single-supply installation.

FAQ

Q1

Is 1756-PAR2 a single power supply?

It is a bundle containing two redundant AC supplies, two power cables and a chassis adapter.

Q2

Can I add the two supply ratings in 1756-PAR2 to double chassis power?

No. Size the chassis load for the specified redundant system; the two supplies do not create a doubled output rating.

Q3

What must I check before fitting 1756-PAR2 to an existing chassis?

Confirm the chassis generation, adapter compatibility and redundant cabling arrangement against the system configuration.

Q4

How can supply status from 1756-PAR2 reach my control system?

The redundant supplies provide annunciator connections. Select and wire the receiving input for the specified annunciator limits.

Q5

Can I see the actual condition of 1756-PAR2 before ordering?

Yes. We confirm the offered condition, provide actual-item photos and test each item before delivery. The agreed warranty is 12 months.

Q6

When can available 1756-PAR2 stock leave after payment?

Available stock is dispatched immediately after payment is received. Courier tracking is provided after dispatch.
