Description
IC695PSA040: Product Overview
The GE IC695PSA040 is a 40-watt universal backplane power supply from GE’s RX3i PACSystem series, a legacy platform renowned for its reliability in industrial automation. As part of the RX3i ecosystem, it acts as the “power backbone” for PLC systems, converting AC/DC input power into regulated DC outputs to supply backplane, logic modules, and relay circuits. Its primary role is to ensure stable power delivery to critical components, which is essential for maintaining process stability and preventing downtime in industrial environments.
Role in Automation Systems:
Positioned as a “core power interface” in RX3i architectures, the IC695PSA040 performs two primary functions:
-
Power Conversion: Converts wide-range AC/DC input power (85–264 VAC/100–300 VDC) into three regulated DC outputs (+5.1 VDC, +3.3 VDC, +24 VDC) to meet the needs of different RX3i modules.
-
Power Distribution: Delivers power to the RX3i backplane, which distributes it to all installed modules (e.g., CPUs, I/O modules, communication modules). The +24 VDC output is specifically designed to power relay output modules, eliminating the need for external power supplies.
Core Functionality:
-
Wide Input Voltage Compatibility: Supports both AC (85–264 VAC) and DC (100–300 VDC) input ranges, making it suitable for global deployment without additional power converters.
-
Regulated Outputs: Provides three stable DC outputs:
-
+5.1 VDC: Powers most RX3i logic modules (up to 6 A).
-
+3.3 VDC: For internal use by RX3i modules with IC695 catalog numbers (up to 9 A).
-
+24 VDC: Powers relay output modules (up to 1.6 A).
-
-
Built-in Protection: Equipped with overload, overvoltage, and overtemperature protection. Isolation between input and backplane minimizes damage from electrical transients.
-
Status Monitoring: Four front-panel LEDs (Power, Fault, Overheat, Overload) provide instant diagnostic feedback for operators and maintenance personnel.
Platform Benefits (RX3i Series):
The IC695PSA040 inherits the RX3i platform’s strengths, including:
-
Reliability: The RX3i system is the industry standard for industrial automation, with a proven track record of 24/7 operation in power plants, refineries, and manufacturing facilities worldwide.
-
Legacy Compatibility: The module is designed to work with existing RX3i components (e.g., backplanes, controllers), reducing the cost of system upgrades.
-
Scalability: Supports expansion with up to four IC695PSA040 units in series (daisy-chained) to provide additional power for large systems.

Core Features & Customer Value
1. Reliable Power Delivery:
The IC695PSA040’s regulated outputs and wide input range ensure stable power delivery to RX3i systems, even in areas with unstable power grids. For example, in a power plant, the module can handle voltage fluctuations (85–264 VAC) and still provide clean DC power to the turbine control PLC, preventing unexpected shutdowns.
2. Flexible Installation:
The wide input voltage range (85–264 VAC/100–300 VDC) eliminates the need for additional power converters, reducing installation costs and complexity. This flexibility is particularly valuable for global companies with facilities in different countries.
3. Rugged Industrial Design:
The module’s operating temperature range (0°C to +60°C) and compact form factor make it suitable for harsh industrial environments. Its DIN rail mounting option simplifies installation in crowded control cabinets, reducing setup time and effort.
4. Easy Troubleshooting:
The four status LEDs (Power, Fault, Overheat, Overload) provide instant visual feedback on the power supply’s status. For example, if the Overload LED turns on, technicians can quickly identify that the module is exceeding its output capacity and take corrective action (e.g., reducing the load).
5. Cost-Effective Scalability:
The ability to daisy-chain up to four IC695PSA040 units allows facilities to expand their power capacity without replacing the entire system. This scalability is ideal for growing manufacturing plants that need to add more I/O modules or controllers.
