GE IC698ACC701

Description

Product Description

The GE IC698ACC701 is a high-performance AC power supply module designed explicitly for the GE Fanuc RX7i PACSystem controller, part of the larger PACSystems family. This module is responsible for converting incoming utility AC power into the stable, isolated DC voltages required by the controller’s VME backplane and all connected I/O modules within the RX7i rack. As the primary power source for the entire rack, the reliable operation of the CPU, communication cards, and I/O hinges on the clean and regulated output provided by the GE IC698ACC701. Its design emphasizes safety, noise immunity, and robust performance in industrial settings, ensuring the foundational power integrity of the automation system. Proper selection and installation of the GE IC698ACC701 are critical first steps in building a reliable RX7i-based control system for demanding applications.

Product Parameters

• Controller Family: GE Fanuc PACSystems RX7i.
• Module Type: AC Power Supply Module.
• Input Voltage: 120/240V AC, selectable via a manual switch.
• Input Frequency: 47-63 Hz.
• Output Power: Provides up to 40A at +5.1VDC and up to 2.0A at +24VDC for the backplane.
• Output Voltages: +5.1VDC (logic power) and +24VDC (for bus communication and I/O).
• Hold-up Time: Typically 20 ms at full load.
• Status Indicators: LED indicators for AC Power OK and DC Power OK.
• Mounting: Occupies a single slot in an RX7i series rack.

Advantages and Features

• Dual Voltage Input: The selectable 120V/240V AC input offers installation flexibility across different power standards.
• High Current Capacity: With 40A on the +5VDC rail, it supports large, densely populated racks with numerous I/O and communication modules.
• Robust Design: Built for industrial environments with protection against input transients and noise.
• Integrated Diagnostics: Front-panel LEDs provide immediate status of both incoming AC and output DC power.
• Backward Compatibility: As part of the PACSystems family, it is designed for seamless integration within systems that may also use legacy Series 90-70 components.

Application Cases in Application Fields

• Power Generation & Distribution: Used in control panels for turbine auxiliaries and substation automation.
• Water/Wastewater Treatment: Provides stable power for PLC racks controlling filtration and pump stations.
• Discrete Manufacturing: Powers controllers overseeing high-speed, precision machine control and safety interlocks in automotive or metal fabrication.
• Material Handling: Supports control systems for conveyor networks and automated storage/retrieval systems (AS/RS).

Comparisons with Competing Products

• Vs. Siemens S7-400 Power Supply (e.g., PS 407): Both are power supplies for high-end PLC racks. The GE IC698ACC701 is optimized for the RX7i VME backplane, while Siemens’ is for the S7-400 backplane. They are not interchangeable and represent parallel solutions within their respective ecosystems.
• Vs. Allen-Bradley ControlLogix Power Supply (e.g., 1756-PA75): Both serve the same core function. The choice is dictated by the chosen PLC platform (ControlLogix vs. PACSystems RX7i). The GE module offers a very high +5V current capacity characteristic of the VME-based RX7i system.
• Vs. Generic/Third-party Power Supplies: Generic supplies lack the guaranteed compatibility, form factor, integrated backplane connector, and direct support from GE for the RX7i system.

Selection Suggestions and Precautions

1. Rack Configuration Audit: Calculate the total +5VDC and +24VDC current draw of all modules in the rack to ensure it does not exceed the 40A and 2.0A limits. Include a safety margin.
2. Input Voltage Verification: Confirm the available plant AC voltage and correctly set the selector switch on the module to either 120V or 240V before applying power.
3. Redundancy Consideration: For mission-critical applications, consider implementing a redundant power supply system as specified in GE’s documentation.
4. Thermal Management: Ensure adequate airflow within the cabinet. The module generates heat under load, and proper ventilation prolongs its life.
5. Genuine vs. Third-Party: For maximum reliability, use the genuine GE IC698ACC701 module rather than third-party clones, especially in critical applications.
