12-24 VDC 40 A DeltaV Bulk Power Supply Redundancy Module

Installation notes

The following information applies only to part number KJ1503X1-BD1. For other DeltaV redundancy modules with similar characteristics, you can obtain documentation from Emerson Global Support Center at 800-833-8314.
Install this redundancy module on a horizontally oriented DIN rail with the label text right-side up.
Keep the following installation clearances: 40 mm on top, 20 mm on the bottom, 5 mm on the left and right sides when the device is loaded permanently with more than 50% of the rated output current. Increase the side clearance to 15 mm if the adjacent device is a heat source such as a power supply.
This redundancy module can be used in one-to-one and n-to-one redundant systems. Use diodes or other switching arrangements to isolate the redundant power supply outputs from each other.
Connect the two input channels to the 100-240 VAC to 24 VDC 20 A DeltaV Bulk Power Supply for redundant applications.

Wiring for redundancy

The 12-24 VDC 40 A DeltaV Bulk Power Supply Redundancy Module can be used in one-to-one and n-to-one applications.

Note

For both one-to-one redundancy and n-to-one redundancy, it is recommended that, if possible, you use separate mains systems for each power supply.
