The IC695PSA140 is a versatile multi-purpose power supply from GE Fanuc, designed specifically for the RX3i PACSystem platform. This module delivers 40 watts of total output power and supports both load sharing and redundancy applications. Consequently, it provides enhanced system reliability for critical industrial processes. The power supply accepts a wide input range of 85 to 264 VAC or 100 to 300 VDC, accommodating global power standards with ease.
Furthermore, the IC695PSA140 generates three distinct output voltages to support various system components. It provides a +5.1 VDC output for logic circuits, a +24 VDC relay output for driving external relays, and a +3.3 VDC output used internally by the backplane and attached RX3i modules. This power supply also includes overcurrent protection and four status LEDs for comprehensive diagnostics.
The IC695PSA140 distinguishes itself through its load sharing and redundancy features. You can install up to four of these power supplies on a single RX3i universal backplane. In a redundant configuration, if one unit fails, the remaining supplies continue to power the system without interruption. This capability ensures maximum uptime for mission-critical applications.
For load sharing applications, multiple IC695PSA140 units distribute the power demand evenly across all connected modules. This approach extends the lifespan of each power supply and prevents any single unit from operating at maximum capacity continuously. Meanwhile, the fault detection circuitry latches the module to OFF when an internal fault occurs. To restore normal operation, you must cycle the input power to reset the unit.
The IC695PSA140 operates with a nominal voltage of 120/240 VAC or 125 VDC. Its AC input range spans from 85 to 264 VAC, while the DC input range covers 100 to 300 VDC. At full load, the module draws 70 watts of input power. The output voltage ranges are precisely regulated: 5.0 to 5.2 VDC for the 5.1V rail, 19.2 to 28.8 VDC for the 24V relay output, and 3.1 to 3.5 VDC for the internal 3.3V supply.
Additionally, the output current capacities are well-defined for each rail. The 5.1 VDC output supports up to 6 amperes with a 7-ampere overcurrent limit. The 24 VDC relay output provides up to 1.6 amperes, while the 3.3 VDC internal output can deliver up to 9 amperes with a 10-ampere limit. The maximum output power available depends on the ambient air temperature around the module, so proper ventilation is essential.
The IC695PSA140 includes four status LED indicators for real-time system monitoring. These LEDs display Power, P/S Fault, Over Temperature, and Overload conditions. Therefore, technicians can quickly identify operational issues without external testing equipment. The power supply also features an internal fusible link in the input line, which serves as a backup protection device.
Overcurrent protection is another critical safety feature of the IC695PSA140. The 5.1 VDC output is limited to 7 amperes, while the 3.3 VDC output is limited to 10 amperes. These limits prevent damage to connected modules in case of a short circuit or excessive load. Furthermore, the module provides input-to-backplane isolation of 250 VAC continuous and 1500 VAC for one minute, ensuring robust protection for sensitive electronics.
The IC695PSA140 offers a ride-through time of 20 milliseconds. This specification indicates how long the power supply can maintain valid outputs during a momentary power failure. For industrial environments with unstable mains power, this feature provides valuable protection against unexpected shutdowns. During this period, the CPU and I/O modules continue operating normally, preventing data loss or process interruptions.
Moreover, the power supply's internal design ensures stable output voltages across varying load conditions. The IC695PSA140 maintains tight regulation on all three output rails, which is essential for sensitive analog and digital circuits. This stability contributes to the overall reliability of the RX3i system in demanding industrial applications.
This power supply occupies two backplane slots on the RX3i universal backplane. Its compact design allows efficient use of rack space while delivering full 40-watt output capacity. The module supports operation in temperatures ranging from 0 to 60 degrees Celsius, with storage temperatures from -40 to 85 degrees Celsius. Additionally, it tolerates relative humidity from 5% to 95% non-condensing.
The IC695PSA140 also meets rigorous industrial standards for vibration and shock resistance. It complies with IEC 60068-2-6 for vibration and IEC 60068-2-27 for shock, ensuring reliable performance in typical factory floor environments. These specifications make it suitable for automotive, discrete manufacturing, chemical, and other heavy industries.
Installing the IC695PSA140 requires attention to several key factors. First, ensure that you are using an RX3i universal backplane, as this power supply is not compatible with other backplane types. Next, insert the module into the designated leftmost slots of the backplane, occupying two adjacent positions. Secure the unit with the retaining screws to maintain mechanical stability.
For redundancy configurations, install multiple IC695PSA140 units on the same backplane. However, remember that you cannot mix this model with other RX3i power supply models on the same backplane. All installed power supplies must be of the same type for proper load sharing. Finally, connect the input power wiring to the terminal block, observing correct polarity for DC operation or line/neutral for AC operation.
Each IC695PSA140 unit ships in an anti-static protective package to prevent damage during transit. The box includes the power supply module, a terminal block connector, and a quick-start installation guide. All orders are dispatched via trusted carriers, including FedEx, UPS, and DHL, with tracking numbers provided for every shipment.
1. Can I use the IC695PSA140 with a standard RX3i backplane?
Yes, the IC695PSA140 is designed exclusively for the RX3i universal backplane. It will not function with older series backplanes.
2. How many IC695PSA140 units can I install in one rack?
You can install up to four IC695PSA140 power supplies on a single RX3i universal backplane for redundancy or load sharing.
3. What happens when a fault occurs in redundant mode?
The faulty IC695PSA140 latches to OFF and the remaining units continue supplying power. You must power cycle the faulty unit to reset it.
4. Can I mix IC695PSA140 with other RX3i power supplies?
No, you cannot mix the IC695PSA140 with other RX3i power supply models on the same backplane. All units must be identical for proper operation.
5. What is the ride-through time of this power supply?
The IC695PSA140 provides a 20-millisecond ride-through time, maintaining valid outputs during brief power interruptions.
