Description

The GE IC698PSA100E is a high-reliability, redundant AC/DC power supply module engineered for the GE Fanuc RX7i and RX3i programmable automation controller (PAC) systems. Delivering 100 watts of stable, regulated +5 VDC and +24 VDC power, this hot-swappable unit supports N+1 redundancy to ensure uninterrupted operation in mission-critical industrial applications—from automotive assembly lines to water treatment plants. With universal input, intelligent diagnostics, and ruggedized design, the GE IC698PSA100E serves as the silent yet essential backbone of continuous control systems where power failure equals production loss.

Application Scenarios

At a Tier-1 automotive stamping facility in Michigan, unplanned press line stoppages due to power supply failures were costing over $ 220.000 per hour in downtime. Legacy non-redundant PSUs would fail without warning during peak summer loads. The plant upgraded its RX7i racks with dual GE IC698PSA100E modules in redundant configuration. Within months, zero power-related outages occurred—even during a brownout that dropped plant voltage to 92 VAC. Maintenance teams now receive early alerts via Proficy Machine Edition when output ripple exceeds thresholds, enabling proactive replacement. This shift from reactive firefighting to predictive resilience highlights how the GE IC698PSA100E transforms power integrity into operational certainty.

Technical Principles and Innovative Values

Innovation Point 1: True Hot-Swap Redundancy with Zero Glitch – The GE IC698PSA100E uses diode-ORing and active load balancing to enable live replacement without interrupting CPU or I/O operation—a critical advantage in 24/7 manufacturing where shutdowns are prohibited.

Innovation Point 2: Dual-Voltage Output Optimized for PAC Architecture – Unlike generic PSUs, the GE IC698PSA100E delivers precisely regulated +5 VDC for logic backplanes and isolated +24 VDC for communication modules (e.g., Ethernet, serial)—eliminating the need for secondary DC/DC converters.

Innovation Point 3: Fanless, Solid-State Reliability – The absence of moving parts allows the GE IC698PSA100E to operate reliably in metal shavings, textile fibers, or chemical vapors that would clog conventional cooling fans—extending MTBF beyond 150.000 hours.

Innovation Point 4: Seamless Integration with Proficy Diagnostics – Real-time status (voltage, current, fault codes) is accessible via GE’s Proficy Machine Edition software, enabling remote health monitoring and integration into predictive maintenance workflows.

Application Cases and Industry Value

A municipal wastewater treatment plant in California deployed RX7i controllers with dual GE IC698PSA100E power supplies across 12 pump stations. Located in coastal enclosures exposed to salt spray and temperature swings, the fanless design prevented corrosion-related failures that plagued earlier fan-cooled units. During a regional blackout followed by unstable generator power, the GE IC698PSA100E maintained clean output—keeping SCADA communication alive and preventing sewage overflow. Over five years, the plant reported 100% power availability and eliminated emergency call-outs for PSU failures. “It just runs,” said the lead controls technician. “We forget it’s there—until we check the logs and see it’s been perfect.”

Installation, Maintenance, and Full-Cycle Support

Installing the GE IC698PSA100E requires snapping it into an RX7i or RX3i backplane until it clicks—no tools needed. Connect AC or DC input using shielded cables rated for the local grid, ensuring proper grounding. For redundancy, install at least two units; the system automatically balances load and indicates “REDUNDANCY ACTIVE” via LED. Verify all output voltages with a multimeter before powering I/O modules.

Maintenance is minimal but recommended annually: inspect terminals for oxidation, clean dust from ventilation slots (if any), and validate redundancy by simulating a module removal. Replace units if the FAULT LED illuminates persistently or output ripple exceeds 50 mVpp. We provide fully tested, burn-in validated GE IC698PSA100E units with restored capacitors and firmware verification—critical for legacy systems beyond original manufacturer support. Our team offers lifecycle services including power budget analysis, redundancy validation, and migration planning to Emerson’s latest PAC platforms.
