Description
Initial Product Description & Link
The core device is GE IC695PSD140, an industrial-grade power supply module developed by GE, specifically designed to provide stable, redundant power to GE RX3i PLC systems and their associated I/O modules. It is a critical component for ensuring uninterrupted operation in industrial automation environments—including manufacturing, power generation, and water treatment—where power fluctuations or outages could cause costly downtime. The product link will be provided later; below is a detailed overview of its design, specifications, and real-world applications.
Core Product Description
GE IC695PSD140 belongs to GE’s RX3i series of power supply modules, engineered to address the reliability needs of modern PLC systems. Unlike basic power supplies, it features a 1+1 redundant design—two independent power supply units (PSUs) are integrated into a single module, ensuring that if one PSU fails, the other immediately takes over (with a switchover time of <1ms) to maintain power to the PLC and I/O modules.
This redundancy is a game-changer for mission-critical applications. For example, in a municipal water treatment plant, GE IC695PSD140 powers a GE RX3i PLC that controls pump stations and chemical dosing systems. If one PSU in the module fails due to a voltage spike, the redundant PSU continues supplying power, preventing the PLC from shutting down and avoiding disruptions to clean water production.
Additionally, GE IC695PSD140 is built for industrial resilience: it tolerates wide input voltage fluctuations (85–264V AC) and operates reliably in extreme temperatures (-20°C ~ +60°C), making it suitable for both indoor control cabinets and harsh on-site environments. It also includes built-in protection against overloads, short circuits, and overheating—further safeguarding the PLC system from damage.

Core Advantages & Features
- 1+1 Redundancy for Uninterrupted Power: The dual-PSU design of GE IC695PSD140 eliminates single points of failure. Unlike non-redundant power supplies, it ensures the PLC system stays online even if one PSU malfunctions—critical for applications where downtime costs thousands of dollars per minute (e.g., automotive assembly lines).
- Wide Input Voltage Tolerance: With an 85–264V AC input range, GE IC695PSD140 works seamlessly in regions with unstable power grids (e.g., remote manufacturing sites) or different global voltage standards (110V AC in North America, 230V AC in Europe). This eliminates the need for external voltage converters.
- Industrial-Grade Durability: Its -20°C ~ +60°C operating range and robust protection features (overload, short-circuit) make GE IC695PSD140 suitable for harsh environments—from cold storage facilities to hot factory floors—where consumer-grade power supplies would fail.
- Simplified Maintenance: LED status indicators and fault logging allow technicians to quickly identify failed PSUs without disassembling the module. The redundant design also means maintenance can be performed on one PSU while the other continues powering the system—no need for planned shutdowns.
Typical Application Scenarios
- Automotive Manufacturing – Assembly Line Control: In a car factory, GE IC695PSD140 powers a GE RX3i PLC that controls robotic welders and conveyor belts. If a PSU fails, the redundant unit keeps the PLC running, preventing the assembly line from stopping and avoiding costly production delays.
- Power Generation – Turbine Monitoring: In a wind farm’s control center, GE IC695PSD140 supplies power to a GE RX3i PLC that monitors turbine performance (e.g., rotor speed, wind direction). The module’s wide input tolerance handles voltage fluctuations from the wind farm’s grid, while redundancy ensures continuous monitoring even if a PSU fails.
- Water Treatment – Pump & Dosing Control: In a wastewater treatment plant, GE IC695PSD140 powers a PLC that controls pumps and chemical dosing pumps. Redundancy prevents PLC shutdowns during power supply failures, ensuring consistent treatment and avoiding non-compliance with environmental regulations.
Comparison with Competitors (vs. a Non-Redundant 24V DC Power Supply)

Selection Recommendations & Usage Precautions
Selection Recommendations
- Match to PLC Power Requirements: Choose GE IC695PSD140 if your GE RX3i PLC system (including I/O modules) requires ≤14A of 24V DC power. For larger systems (e.g., >14A), pair it with a GE IC695PSD240 (24A output) to avoid overloading.
- Prioritize for Mission-Critical Systems: Use GE IC695PSD140 in applications where downtime is unacceptable (e.g., emergency response systems, continuous manufacturing). For non-critical use cases (e.g., lab testing), a non-redundant power supply may be more cost-effective.
- Check Compatibility: Ensure the module is compatible with your GE RX3i CPU model (e.g., IC695CPU330). While it works with third-party 24V DC devices, avoid connecting loads that exceed 14A to prevent overloads.
Usage Precautions
- Proper Wiring: Connect the input to a dedicated AC circuit (20A breaker recommended) to avoid voltage drops. Use 14AWG or thicker wires for the 24V DC output to minimize power loss, especially for long cable runs (>5 meters).
- Ventilation: Install GE IC695PSD140 with at least 20mm of space on all sides to ensure adequate airflow. Overheating can reduce PSU lifespan or trigger shutdowns—avoid mounting it near heat sources (e.g., variable frequency drives).
- Regular Inspection: Monthly, check the LED indicators to confirm both PSUs are operational. Annually, use a multimeter to verify the 24V DC output (should be 24V ±0.5V) and clean dust from the module’s vents to prevent overheating.
