Description
GE BK698CPA15B0 Power Supply Module for Series 90-70
The GE BK698CPA15B0 is a high-performance power supply module designed specifically for the GE Fanuc Series 90-70 programmable logic controller (PLC) systems. As an integral component of the 90-70 family, this power supply unit (PSU) provides the necessary DC power to the CPU rack and expansion racks, ensuring stable and reliable operation of the entire control system. The BK698CPA15B0 converts standard AC line voltage into the regulated DC voltages required by the backplane, processor modules, and I/O cards, making it a foundational element for any Series 90-70 installation.
Product Parameters
The electrical specifications of the GE BK698CPA15B0 define its capabilities in industrial environments. This module typically accepts a wide range AC input, commonly 85-264 V AC (auto-ranging), at 47-63 Hz, making it suitable for global applications without voltage selection switches. It provides multiple DC outputs to the backplane, primarily +5 V DC for logic circuits and +24 V DC for field-side I/O loops. The BK698CPA15B0 offers a substantial output capacity, often rated up to 15 Amps on the +5 V rail, depending on the specific revision. It features overvoltage and overcurrent protection, shutting down safely in fault conditions. The module is designed for hot-swap capability in many rack configurations, though proper procedures must always be followed. It includes diagnostic LEDs for input power OK and DC output OK status.
Advantages and Features
Integrating the GE BK698CPA15B0 into a Series 90-70 system provides numerous operational benefits. A primary advantage is its robust construction, designed to withstand the electrical noise and fluctuations common in heavy industrial environments. It features universal input, simplifying inventory management since the same BK698CPA15B0 can be used in facilities with different supply voltages. The power supply includes a built-in fan for forced-air cooling, ensuring stable operation even when the rack is fully loaded with power-hungry modules. Additionally, it provides a battery backup interface for the CPU’s RAM memory, protecting critical program data and variables during power outages. The GE module’s high Mean Time Between Failures (MTBF) makes it a trusted choice for critical infrastructure applications.
Application Cases
The GE BK698CPA15B0 is deployed across a wide spectrum of heavy industries where Series 90-70 systems remain in operation. In steel production facilities, these power supplies energize the complex control systems managing rolling mills and furnace controls. Water and wastewater treatment plants rely on the BK698CPA15B0 to power the logic controlling pumps, valves, and filtration systems across distributed plant sites. In the power generation sector, particularly in hydroelectric and thermal plants, the GE BK698CPA15B0 provides the stable power foundation for turbine control and balance-of-plant automation. Many petrochemical facilities with legacy automation infrastructure continue to depend on these power supplies for critical process control applications where system upgrades have been deferred.
Comparison with Competing Products
When comparing the GE BK698CPA15B0 to power supply offerings from other major PLC platforms, several distinctions emerge. Unlike the modular power supplies used in Allen-Bradley ControlLogix systems, the BK698CPA15B0 is rack-integrated and specific to the Series 90-70 backplane architecture. Compared to Siemens S7-400 power supplies (like the PS 407), the GE unit offers comparable capacity but with different diagnostic interfaces and form factors. The GE BK698CPA15B0 is often praised for its conservative electrical design and high component derating, which contributes to its legendary longevity in the field. While modern PLC platforms offer higher efficiency ratings, the BK698CPA15B0 remains the standard for the vast installed base of Series 90-70 systems, where reliability and proven performance outweigh the benefits of newer technologies.
Selection Suggestions and Precautions
Selecting the correct GE BK698CPA15B0 requires careful consideration of your system configuration. First, verify your rack type and the total current requirements of all modules in the rack; undersizing the power supply can lead to erratic system behavior and premature failure. When replacing an existing unit, always check the revision level of the BK698CPA15B0 against your system documentation, as different revisions may have slightly different output specifications or diagnostic features. A critical precaution involves the cooling fan: ensure that the fan intake is not obstructed and that the filter (if present) is cleaned regularly, as fan failure is a leading cause of power supply overheating. When installing a new GE power supply, always verify that the AC input voltage selector (if present) is correctly set for your facility voltage. Finally, be aware that the BK698CPA15B0 contains high-voltage capacitors that retain charge after power-off; only qualified personnel should perform internal repairs or inspections.
