Product Parameters

• Product Type: Backplane Power Supply Module
• System Series: GE PACSystems RX3i and RX7i.
• Input Voltage: Typically accepts a wide-range AC input (e.g., 85-264 VAC, 47-63 Hz) and often a DC input range (e.g., 88-250 VDC).
• Output Voltage: Provides +5 VDC and +3.3 VDC for the logic power of modules on the backplane.
• Output Current/Power:
  • +5 VDC Output: Typically rated for 10 Amps (50 Watts) continuous.
  • +3.3 VDC Output: Typically rated for a specific current (e.g., shared or dedicated capacity).
• Total Power: Rated for a specific maximum output power (e.g., 100 Watts).
• Hold-up Time: Designed to maintain output voltage for a short period (e.g., 20ms) after input power loss, allowing the CPU to perform an orderly shutdown.
• Protection: Features protection against overload, short circuit, and overtemperature.
• Status Indicators: LEDs for AC Power OK, DC Power OK (+5V), and Fault conditions.
• Mounting: Plugs into the dedicated power supply slot (typically the left-most slot, slot 0) in an RX3i Universal Backplane (IC698CHSxxx).

Advantages and Features

• High Power Capacity: The GE IC698PSA100D provides ample power (up to 100W) to support large, high-density configurations of CPU, analog, digital, and special function modules in an RX3i rack.
• Wide Input Voltage Range: Can operate from virtually any global industrial AC or DC supply voltage without the need for taps or switches, simplifying inventory and installation.
• High Reliability and Stability: Provides tightly regulated and low-noise DC power, which is critical for the reliable operation of sensitive analog modules and digital communications.
• Hot-Swappable (in Supported Systems): In systems designed with redundant power supplies, the GE IC698PSA100D can be hot-swapped, allowing for replacement without system shutdown.
• Comprehensive Diagnostics: Clear LED status indicators provide immediate visual feedback on the health of the power supply, aiding in rapid troubleshooting.
• Seamless System Integration: As the designated power supply for RX3i racks, the GE IC698PSA100D is mechanically and electrically designed for perfect compatibility, ensuring optimal performance and safety.

Application Cases in Key Fields

• Manufacturing & Machining: Powering large RX3i systems that control complex automated assembly lines with numerous I/O points and servo drives.
• Material Handling: Supplying power to controllers managing extensive conveyor networks, sortation systems, and automated storage/retrieval systems (AS/RS).
• Water and Wastewater Treatment: Powering central RX3i controllers that monitor and control large treatment plants with hundreds of I/O points across various processes.
• Food and Beverage Processing: Supporting control systems for batch processing, packaging lines, and material handling where a high number of analog and digital signals are required.
• Infrastructure Management: Used in control systems for tunnel ventilation, bridge de-icing, or airport baggage handling systems.

Comparisons with Competing Products

• Vs. Other RX3i Power Supplies (e.g., IC698PSA050, IC698PSA300): The GE IC698PSA100D sits in the mid-range of power capacity. The PSA050 has lower capacity (50W), and the PSA300 has higher capacity (300W). Selection is based on the total calculated load of the rack.
• Vs. Power Supplies for Competing PLCs (e.g., Allen-Bradley 1756-PA72/A): Competing power supplies serve the same function but for different physical racks and electrical specifications. The GE IC698PSA100D is optimized for the RX3i backplane voltage and current requirements.
• Vs. Generic/Third-Party Power Supplies: While a generic 5V/10A supply might fit electrically, it would lack the specific form factor, status signaling to the CPU, hot-swap capability, and mechanical mounting of the genuine GE IC698PSA100D. Using non-genuine supplies can void warranties and cause system instability.
• Vs. Older GE Series 90-30 Power Supplies: The RX3i system and the GE IC698PSA100D represent a newer generation with higher power density, wider input range, and better diagnostics than legacy 90-30 supplies.

Selection Suggestions and Precautions

• Selection Advice:
  1. Perform a Detailed Power Budget: Calculate the total +5V and +3.3V current draw of every module (CPU, I/O, comms) planned for the rack using the specifications in their data sheets. The total must be less than the rated output of the GE IC698PSA100D, with a recommended 20-30% safety margin.
  2. Consider Future Expansion: When sizing the power supply, account for potential future addition of modules. It is often cost-effective to select a supply with more capacity initially.
  3. Verify Redundancy Needs: If the application requires high availability, plan for a redundant power supply system from the start, which requires a specific backplane (IC698CHSxxR) and a second power supply.
  4. Check Input Power Source: Ensure the plant’s AC or DC source is within the input range of the GE IC698PSA100D and is properly fused.
• Important Precautions:
  1. Correct Slot Installation: The power supply must be installed in the designated slot (usually slot 0). Installing it in a regular I/O slot can damage the module and the backplane.
  2. Adequate Ventilation: Ensure there is adequate airflow around the power supply and the entire rack. Do not obstruct vents. Overheating is a primary cause of power supply failure.
  3. Secure Wiring: Torque the input power terminals to the specified value. Loose connections can overheat and cause fire hazards or voltage drops.
  4. Observe Safety Procedures: Always disconnect input power before installing, removing, or wiring the GE IC698PSA100D. Treat all power connections as potentially live until verified.
  5. Do Not Mix Power Supply Models in Redundant Pair: If using redundancy, both power supplies must be the same model (e.g., two GE IC698PSA100D modules) to ensure proper load sharing and operation.
