ABB Bailey IPESW13 | INFI 90 Power Chassis

The ABB Bailey IPESW13 provides mechanical and electrical support for INFI 90 modules. This power chassis houses up to 16 I/O, controller, or communication modules in a single rack. You can mount it in standard 19-inch cabinets using front or rear access. It distributes DC power from external supplies to all inserted modules. Consequently, this chassis forms the physical foundation of your Bailey DCS installation.

Functional Features and Chassis Design

The ABB Bailey IPESW13 accepts any INFI 90 module in any slot position. You can mix I/O, processors, and communication cards freely within the same chassis. The passive backplane requires no configuration or software setup. Furthermore, the chassis includes a dedicated power input terminal block for external supplies.

This power chassis features a removable rear cover for easy cable access. The steel construction provides electromagnetic shielding for sensitive analog modules. Additionally, the chassis includes a ground bus bar for system earthing. You can mount two chassis side-by-side in a standard 19-inch cabinet.

Installation and Wiring Guidelines

First, mount the ABB Bailey IPESW13 securely into your 19-inch cabinet using four screws. Next, connect the external DC power supplies to the rear terminal block. Then, install the power distribution fuses for each voltage rail. Finally, insert your modules starting from the leftmost slot.

You must ensure adequate ventilation around the chassis for passive cooling. The module does not include any internal energy storage or battery backup. Always use the correct gauge wire for power supply connections. Furthermore, verify that total module current does not exceed chassis ratings.

This power chassis works perfectly for new INFI 90 installations and expansions. You can also use it to replace damaged chassis in existing systems. The ABB Bailey IPESW13 supports both simplex and redundant power configurations. You can hot-swap most modules without powering down the entire chassis.
