GE IC695PSD140B PACSystems RX3i Redundant Power Supply Module
Product Overview
The GE IC695PSD140B is a high-reliability redundant power supply module engineered for GE’s PACSystems RX3i automation platform, delivering uninterrupted power to critical control components in industrial environments. As a dual-slot module, the IC695PSD140B supports N+1 redundancy, meaning two units can operate in parallel—one active and one standby—with automatic failover if the primary supply fails. This design ensures zero downtime in safety-critical systems such as nuclear reactor controls, offshore platform automation, and pharmaceutical manufacturing lines.
The IC695PSD140B accepts 100–240V AC wide-range input and converts it to 5V DC (15A) and 24V DC (3A) outputs, powering RX3i controllers, I/O modules, and communication cards like the IC695CMU310. Its 90% efficiency minimizes energy loss, reducing operational costs in 24/7 facilities. The module operates across 0°C to 60°C and features a rugged metal enclosure that withstands vibration, humidity, and electrical noise—ideal for harsh settings like steel mills and chemical plants.
Within the RX3i ecosystem, the IC695PSD140B integrates seamlessly with racks such as IC695CHS017 and terminal blocks like IC695TBM302, forming a robust power infrastructure. LED indicators provide real-time status for input voltage, output health, and redundancy status, simplifying diagnostics. Compliance with UL 508 and IEC 61010 standards underscores its reliability in regulated industries, where power interruptions could lead to catastrophic losses.

Main Features and Advantages
Redundant Reliability
The IC695PSD140B’s N+1 redundancy eliminates single points of failure. If the active unit detects overvoltage, overcurrent, or internal faults, the standby unit automatically takes over within 2ms—faster than the response time of most control systems. This ensures uninterrupted power to RX3i controllers like IC695CPU313 and I/O modules such as IC695ALG616, critical for preventing process shutdowns in semiconductor fabs or oil refineries.
Wide-Range Flexibility
With 100–240V AC input, the module adapts to global power grids, making it suitable for multinational facilities. It delivers 5V DC (15A) for digital components and 24V DC (3A) for analog sensors and actuators, eliminating the need for separate power supplies. This integration reduces wiring complexity and cabinet space—valuable in compact environments like marine control rooms.
Robust Protection Mechanisms
Built-in safeguards include overvoltage clamping (prevents damage from power surges), current limiting (shuts down during short circuits), and thermal shutdown (protects against overheating). These features extend the lifespan of connected components, reducing maintenance costs in harsh settings like mining operations, where electrical noise and voltage fluctuations are common.
Industrial-Grade Durability
Encased in a rugged metal housing, the IC695PSD140B operates reliably in extreme conditions: 0°C to 60°C temperatures, 20g shock resistance, and 5–95% humidity. Its conformal coating resists dust, moisture, and chemical exposure, ensuring long-term performance in pulp and paper mills or offshore drilling platforms.
Seamless RX3i Integration
The module plugs directly into RX3i racks, using the backplane to distribute power. It pairs with IC695CHS017 (17-slot rack) and IC695LRE001 (rack extender), enabling scalable power distribution in large systems. LED indicators for input, output, and redundancy status simplify troubleshooting, while a front-panel test button allows manual failover checks during maintenance.
Application Fields
The GE IC695PSD140B is indispensable in industries where power interruptions risk safety, productivity, or compliance:
- Nuclear Power: Powers RX3i controllers in reactor protection systems, where redundancy is mandated by regulatory standards (e.g., 10CFR50). The module’s failover speed prevents erroneous shutdowns during grid fluctuations.
- Offshore Oil & Gas: Ensures continuous operation of wellhead pressure monitors and compressor controls. Its wide input range adapts to unstable generator power, while rugged design withstands salt spray and vibration.
- Pharmaceutical Manufacturing: Supports cleanroom automation systems, where power loss could compromise batch integrity. Redundant 24V DC outputs maintain operation of filling machines and environmental sensors.
- Metallurgy: Powers RX3i-based rolling mill controls, withstanding the electrical noise and temperature swings of steel production. Its overcurrent protection prevents damage to expensive servo drives during mechanical jams.

Installation and Maintenance
Pre-installation preparations: Verify the RX3i rack is grounded and aligned horizontally. Ensure input voltage matches the facility’s supply (100–240V AC) and use shielded cables to reduce EMI. Mount the IC695PSD140B in the first two slots of the rack, securing it with captive screws. Connect input power to terminal L/N/PE and output devices to the 5V/24V terminals, following GE’s wiring diagram to avoid reverse polarity.
Maintenance suggestions: Conduct monthly visual inspections to check for loose terminals, damaged wires, or dim LEDs. Clean dust from ventilation slots using compressed air to prevent overheating. Quarterly, test redundancy failover by disconnecting the primary unit and confirming the standby takes over within 2ms (use an oscilloscope for verification). Replace aging units every 5–7 years to prevent unexpected failures—critical in 24/7 operations like power plants. When replacing the IC695PSD140B, label wires first and retest all outputs post-installation.
