GE IC698PSA100E

Description

Product Description

GE IC698PSA100E is a high-capacity, rack-mounted AC power supply module designed for the GE Fanuc Series 90-70 PLC system, also known as the RX7i platform. This module, the IC698PSA100E, is responsible for converting the incoming plant AC line voltage into the stable, clean DC voltages required to power all other components within the PLC rack, including the CPU, I/O modules, and communication cards. The primary function of the GE IC698PSA100E is to provide reliable and regulated power, which is the foundational requirement for the entire control system’s operation. It ensures that the sensitive electronics on the controller and I/O modules receive power within strict tolerances, preventing malfunctions or data corruption. Selecting a robust power supply like the IC698PSA100E is a critical step in designing a reliable automation cabinet, as its failure will lead to a complete shutdown of the PLC rack. The GE IC698PSA100E is engineered to deliver the necessary power for large, high-density configurations typical of the 90-70 series.

Product Parameters / Technical Specifications

• Manufacturer: GE Fanuc (now part of Emerson)
• Series: Series 90-70 / RX7i PLC System
• Functional Designation: AC Power Supply Module
• Input Voltage: Accepts a range of AC input voltages, typically 85-132 VAC or 170-265 VAC, selectable via a switch or terminal wiring. Frequency is usually 47-63 Hz.
• Output Voltages: Provides the standard DC bus voltages for the VME backplane, primarily +5 VDC for logic and likely +/-12 VDC or +24 VDC for communications and certain I/O functions.
• Output Power Rating: Rated for a specific total output power (e.g., 100 Watts as suggested by the model number “100”), which dictates how many modules can be installed in the rack.
• Mounting: Installs into the left-most slot (Slot 0) of an IC698 series chassis (e.g., IC698CHSxx). It connects directly to the backplane to distribute power.
• Protections: Includes built-in protections against overvoltage, overload, and short-circuit conditions.
• Status Indicators: Features LED indicators for power status (AC OK, DC OK) and fault conditions.

Advantages and Key Features

• High Power Capacity: Designed to support large rack configurations filled with high-density I/O modules and a powerful CPU, making it suitable for complex applications.
• Wide Input Voltage Range: Can accommodate fluctuations in plant AC power without disruption, enhancing reliability in areas with unstable grid power.
• Robust Regulation and Filtering: Provides tightly regulated DC output with low noise and ripple, which is essential for the stable operation of digital logic and analog measurement circuits.
• Integrated Diagnostics: LED status indicators allow for immediate visual confirmation of operational health, facilitating quick troubleshooting of power-related issues.
• Backplane Integration: Delivers power directly through the chassis backplane, eliminating the need for complex external power distribution wiring within the rack.
• Hot-Swappable Capability: In systems with redundant power configurations, the GE IC698PSA100E can typically be replaced without shutting down the entire control system.

Application Cases in Industry

• Large-Scale Process Automation: Used as the primary rack power supply in 90-70 systems controlling chemical processing plants, oil refineries, or large batch operations with extensive I/O counts.
• Material Handling Systems: Powers the controller for complex automated storage and retrieval systems (AS/RS), airport baggage handling, or large conveyor networks.
• Power Generation (Balance of Plant): Provides reliable power for PLCs controlling coal handling, water treatment, and flue gas desulfurization systems.
• Metals and Mining: Supports the control system for rolling mills, crushers, and mineral processing plants where the environment is harsh and system reliability is paramount.

Comparison with Competing Products

Selection Suggestions and Precautions

1. Verify Input Voltage Requirement: Before installation, confirm the factory-configured input voltage range of your specific GE IC698PSA100E unit (e.g., 120VAC vs. 240VAC) and ensure it matches your cabinet’s AC supply voltage. Incorrect connection can cause immediate damage.
2. Calculate Total Backplane Load: Sum the power consumption of all modules intended for the rack (CPU, I/O, comms). Ensure the total is within the rated output capacity of the IC698PSA100E. Overloading will cause the supply to shut down or fail.
3. Correct Chassis Compatibility: The power supply must be installed in a compatible IC698 series chassis (e.g., IC698CHS017, IC698CHS109). Verify the chassis model accepts this PSU model.
4. Proper Grounding: Ensure the cabinet and the power supply’s ground terminal are connected to a high-quality earth ground. This is critical for safety and for mitigating electrical noise.
5. Redundancy Planning: For mission-critical applications, consider implementing a redundant power supply system from the start. This requires a specific chassis (with two power supply slots) and proper configuration.
6. Legacy System Awareness: The 90-70 series is a legacy platform. When sourcing the GE IC698PSA100E, factor in availability from the aftermarket and ensure the supplier can verify the module’s functionality. New units are scarce.
