GE Fanuc IC695PSA140 Multi-Purpose Power Supply

The GE Fanuc IC695PSA140 is a high-performance, multipurpose power supply module developed specifically for the PACSystems RX3i controller platform. This module provides essential power distribution for the RX3i Universal Backplane. Because it supports both AC and DC input sources, it offers significant installation flexibility across various industrial environments. Furthermore, this unit occupies two slots on the backplane. It serves as a reliable energy foundation for complex automation systems that require stable voltage regulation and high uptime.

Advanced Load Sharing and Redundancy

A standout feature of the IC695PSA140 is its capability for load sharing and hardware redundancy. Specifically, users can install up to four of these power supplies within a single RX3i rack to create a highly resilient system. If one module fails, the remaining units automatically compensate for the load. Therefore, this power supply is an ideal choice for critical applications where a power loss could lead to costly production downtime. In addition to redundancy, this multi-unit configuration allows the system to support a larger number of high-power I/O modules than a single supply could handle alone.

Multi-Rail Voltage Output and Protection

The IC695PSA140 delivers three distinct output voltages to ensure compatible RX3i modules function correctly. It provides +3.3 VDC and +5.1 VDC for internal logic operations, along with a +24 VDC relay output for driving field devices. To maintain system safety, the module incorporates advanced current-limiting technology. For instance, the 5.1V rail features a 7-Ampere limit, while the 3.3V rail is limited to 10 Amperes. Moreover, the unit includes an internal overtemperature sensor. This sensor triggers an automatic shutdown if the internal temperature exceeds safe operating limits, effectively protecting the hardware from permanent damage.

Diagnostics and Fault Monitoring

Reliability is further enhanced through comprehensive visual diagnostics. The front faceplate features four specialized LED indicators. These lights allow operators to quickly verify power status or identify issues such as internal faults, overtemperature conditions, and circuit overloads. Additionally, the module provides a 20-millisecond “ride-through” time. This means the PLC can continue operating during brief voltage dips or power flickers without resetting. Consequently, maintenance teams can identify and resolve power quality issues before they result in a total system failure.
