ABB Bailey IPCHS01 | INFI 90 Power Module Chassis Board

The ABB Bailey IPCHS01 distributes DC power to modules inside INFI 90 chassis assemblies. This chassis board mounts directly onto the backplane of Bailey control racks. It accepts input from external power supplies and routes clean voltage to each slot. You can use it in both process control and data acquisition cabinets. Consequently, this board ensures stable power delivery across all installed I/O modules.

Functional Features and Power Distribution

The ABB Bailey IPCHS01 routes three separate voltage rails across the chassis. You can connect external power supplies to the dedicated input terminals. The board includes onboard fuses for overcurrent protection on each rail. Furthermore, the passive design contains no active components that can fail over time.

This chassis board provides individual power filtering for each module slot. The gold-plated edge connectors resist corrosion for reliable electrical contact. Additionally, the PCB layout minimizes voltage drops across long backplane runs. You can replace the board without disconnecting field wiring from individual modules.

Installation and Replacement Guidelines

First, power down the entire INFI 90 chassis and remove all installed modules. Next, unscrew the old chassis board from its mounting standoffs. Then, position the ABB Bailey IPCHS01 carefully over the guide rails. Finally, secure it using all original screws with even torque.

You must inspect each fuse before installing the board into a live system. The module does not include any energy storage or battery backup functionality. Always verify correct voltage polarity from your external power supplies. Furthermore, use a ground strap to prevent electrostatic discharge during handling.

This power board works perfectly for refurbishing older Bailey INFI 90 racks. It fits all standard chassis including ABB Bailey IPCHS01 compatible housings. You can also use it to build custom DCS configurations from spare parts. The passive design means zero configuration or software setup after replacement.
