Advantages and Features

The GE IC698PSA100E offers significant advantages for mission-critical control applications.

• Universal AC Input: The auto-ranging input capability allows the GE IC698PSA100E to operate on any global AC power grid without manual configuration or jumper changes. This simplifies commissioning and reduces inventory complexity for global OEMs and end users.

• High Efficiency and Reliability: With a typical efficiency rating exceeding 85%, the GE IC698PSA100E generates less heat than comparable power supplies, extending the lifespan of both the power supply itself and adjacent modules. The unit is designed for continuous 24/7 operation in harsh industrial settings.

• Integrated Diagnostics: The GE IC698PSA100E provides comprehensive status feedback via LED indicators and, when used with a compatible CPU, can report power supply health and input voltage levels to the controller. This enables predictive maintenance strategies and remote troubleshooting.

• Hot Swap Capability (with precautions): While the RX7i system supports live insertion of I/O modules, the GE IC698PSA100E is designed for rapid replacement. In redundant power configurations, a failed unit can be replaced without shutting down the system, maximizing uptime.

• Robust Isolation: The module provides 1500 VAC isolation between input and output, protecting sensitive backplane electronics from surges and transients commonly found in industrial power feeds.

Application Cases

The GE IC698PSA100E is deployed across a wide range of heavy industries where system uptime is critical.

• Power Generation: In a combined-cycle power plant, the GE IC698PSA100E powers the RX7i controller responsible for balance-of-plant (BOP) systems, including cooling towers, fuel gas skids, and auxiliary pumps. Its universal input capability allows seamless integration with existing station power infrastructure.

• Metal Processing: In a steel rolling mill, the GE IC698PSA100E provides stable power to the RX7i system controlling hydraulic positioning systems and motor drives. The module’s ability to withstand voltage sags and surges common in heavy industrial environments ensures continuous operation during peak load events.

• Water/Wastewater Treatment: Municipal water treatment facilities utilize the GE IC698PSA100E to power RX7i controllers managing filtration, chemical dosing, and pump stations. The module’s reliability and diagnostic capabilities allow remote operators to verify power status across distributed facilities.

Comparison with Competing Products

When compared to power supply modules from other major PLC platforms, the GE IC698PSA100E offers distinct positioning:

The GE IC698PSA100E differentiates itself through higher output capacity (100 watts) compared to many competing form factors, making it particularly suitable for large chassis configurations with high I/O counts or power-hungry communication modules.

Selection Suggestions

When selecting the GE IC698PSA100E for your automation project, consider the following:

1. System Power Budget: Calculate the total power consumption of all modules in your RX7i chassis, including the CPU, I/O modules, and communication cards. The GE IC698PSA100E provides 100 watts of total output. If your configuration exceeds this, consider the higher-capacity GE IC698PSA200E (200 watt) or a redundant power configuration using two GE IC698PSA100E units with a redundant power supply backplane.

2. Chassis Compatibility: The GE IC698PSA100E occupies two slots (slots 1 and 2) in the RX7i chassis. Ensure your chassis selection has sufficient physical space. For applications requiring a single-slot power supply, evaluate the GE IC693PWR321 (for RX3i) or alternative form factors.

3. Redundancy Requirements: For critical applications where power supply failure cannot be tolerated, specify a redundant power supply backplane (such as the IC698CHS117) that accepts two GE IC698PSA100E modules. This configuration provides automatic failover without process interruption.

4. Environmental Considerations: The standard GE IC698PSA100E is rated for 0°C to 60°C operating temperature. If your application involves extreme ambient temperatures (such as outdoor enclosures or desert installations), verify that the module meets your environmental requirements or consider extended temperature range alternatives.

Precautions

• Wiring and Grounding: Proper grounding is essential for reliable operation of the GE IC698PSA100E. Connect the ground terminal to a low-impedance earth ground per GE installation guidelines. Inadequate grounding can result in erratic system behavior and increased susceptibility to electrical noise.

• Fusing: The GE IC698PSA100E includes internal fusing, but an external branch circuit protection device (fuse or circuit breaker) should be installed upstream per local electrical codes. Use appropriately sized overcurrent protection based on the input voltage and system configuration.

• Power Sequencing: While the GE IC698PSA100E provides stable outputs upon power-up, ensure that field devices powered by the +24 VDC output do not create excessive inrush currents. Inductive loads (solenoids, contactors) should have external suppression diodes to prevent back-EMF from damaging the power supply or other backplane components.

• Hot Swap Limitations: Although the GE IC698PSA100E can be replaced with power applied in redundant configurations, exercise extreme caution. In non-redundant systems, removing the power supply will cause an immediate system shutdown. Always verify the configuration before performing live maintenance.

• Storage and Handling: Store the GE IC698PSA100E in an ESD-safe environment prior to installation. Exposure to moisture or corrosive atmospheres can compromise the module’s conformal coating and long-term reliability. If the module has been stored for an extended period, allow it to acclimate to ambient conditions before applying power.
