Functional Description

The ABB Bailey PHARPSCH100000 acts as the primary frame for system power distribution. When populated with PHARPS-series modules, it converts and channels electrical power to the entire control network through its internal bus. The chassis ensures that all connected modules receive stable, filtered, and isolated power while maintaining proper grounding and shielding for noise immunity.

Its modular structure allows users to install multiple power modules for redundant or load-sharing configurations, enhancing system reliability. If one module fails, the second automatically continues supplying power, ensuring uninterrupted operation.

The built-in power backplane connects to the control system via high-reliability connectors, providing clean electrical contact and minimizing voltage drop. LEDs on the front panel give clear visual feedback of power module status, simplifying system diagnostics.

Applications

The PHARPSCH100000 chassis is an integral component of ABB Bailey automation systems used in various industries, including:

Oil and Gas Plants: Ensures reliable power for process control units and safety systems.
Power Generation: Provides continuous power to turbine control and monitoring modules.
Chemical and Petrochemical Plants: Supports stable operation of distributed controllers and I/O devices.
Pulp and Paper Mills: Powers control and monitoring modules for precision manufacturing processes.
Water Treatment Facilities: Supplies redundant power for monitoring pumps, valves, and actuators.

By providing a robust and reliable foundation for the power modules, the chassis enhances the overall system availability and reduces unplanned downtime.

Performance and Reliability

The PHARPSCH100000 is engineered with ABB’s advanced design principles for long-term dependability. Its power distribution architecture ensures minimal voltage drop across all connected modules. The use of high-quality bus connectors and thick copper traces allows stable power flow under varying loads.

The chassis also features passive cooling and vibration-resistant mounting points, which contribute to maintaining consistent electrical performance in harsh industrial environments. All materials used in the construction are flame-retardant and comply with global industrial safety standards.
