Product Introduction
When system downtime due to power supply failure threatens your production, the GE IC695PSD140 Power Supply Module delivers reliable performance and integrated diagnostics. As part of the PACSystems RX3i family, this DC power supply module accepts 18–30 VDC input and provides up to 60 W input power at full load. Its three regulated outputs (5.1 VDC, 3.3 VDC, and 24 VDC) support backplane logic, I/O, and relay circuits. Four LED indicators—Power, P/S Fault, Overtemperature, and Overload—enable real-time status monitoring, helping technicians quickly identify and resolve issues before they escalate. Designed with load sharing and redundancy in mind, the IC695PSD140 ensures continuous operation in demanding industrial environments.
Technical Specifications Breakdown
The GE IC695PSD140 delivers key performance metrics:
-
Input Voltage Range: 18–30 VDC (nominal 24 VDC)
-
Outputs: Three isolated rails: 5.1 VDC (0–6 A), 3.3 VDC (0–9 A), and 24 VDC (0–1.6 A)
-
Output Power: 40 W total (30 W max each for 5.1 V and 3.3 V rails)
-
Redundancy Support: Up to four units can be daisy-chained in a single backplane for N+1 or load-sharing configurations
-
Diagnostic LEDs: Power (green/amber), P/S Fault (red), Overtemperature (amber), Overload (red)
These specifications make the IC695PSD140 suitable for critical automation systems where power integrity is essential. The 150 mV ripple and noise figures ensure clean power delivery to sensitive electronics.
Application Scenarios
In continuous process industries such as chemical plants, oil refineries, and power generation, the GE IC695PSD140 provides reliable DC power for PACSystems RX3i controllers and I/O racks. For example, in a refinery control system, the module’s redundancy capabilities allow two power supplies to share the load; if one fails, the other instantly takes over, preventing production stoppages. In manufacturing assembly lines, the diagnostic LEDs help maintenance teams pinpoint power faults quickly, reducing mean time to repair (MTTR). The 24 VDC relay output can directly power external solenoids and actuators without additional converters.
Installation & Setup Guidance
The GE IC695PSD140 installs into an RX3i universal backplane, occupying two slots. Use wire sizes #14–22 AWG for terminal connections, and ensure each input terminal does not exceed 6 A. The front-panel On/Off switch controls the module—leave it ON in load-sharing setups to maintain system qualification. If using multiple IC695PSD140 units, connect them to the same power source for proper operation. No jumper or DIP switch configuration is required; the module auto-detects backplane type.
Maintenance & Reliability
Routine checks of the four status LEDs provide early warning of potential failures. The Overtemperature and Overload LEDs indicate thermal or current overload—should these activate, reduce ambient temperature or reduce load immediately. The module’s design eliminates electromechanical wear points (no relays, no fans), resulting in long service life. In redundant systems, test each power supply individually by simulating a failure (e.g., turning off one unit) to confirm the backup operates correctly. Avoid mixing the IC695PSD140 with IC695PSD040 or IC695PSA040 modules in redundancy or increased capacity modes; doing so may cause equipment damage.
Selection Guide & Purchasing Advice
Before purchasing the GE IC695PSD140, confirm your system’s backplane compatibility (RX3i universal only). Verify that your required output current does not exceed the per-rail limits: 6 A at 5.1 V, 9 A at 3.3 V, and 1.6 A at 24 V. For N+1 redundancy, order at least two units and ensure they are from the same revision. UBEST Automation, your trusted source for industrial automation spares, stocks genuine IC695PSD140 modules.
