Functional Description

IC695PSD040 is a Power Supply Module developed by GE Fanuc. It is a high-quality 40-Watt Power Supply Module developed by GE Fanuc, designed specifically for the RX3i PACSystems series. This power supply is integral to providing the necessary power to the various modules within the RX3i product line. It plays a crucial role in powering the system and maintaining operational stability across the connected modules.

Features

• It operates within a specified input voltage range of 18 VDC to 30 VDC. It provides three distinct output voltages to power different components within the RX3i system:
  • +5.1 VDC output: This output is used to power various system components.
  • +24 VDC relay output: It powers circuits on Output Relay modules.
  • +3.3 VDC output: This is used internally by RX3i modules with IC695 catalog numbers.
• An important feature is that only one power supply can be installed in a PACSystems RX3i Universal Backplane.
• This module cannot be used in redundant or increased capacity modes with other RX3i power supplies, and using it with another power supply could result in damage.
• If additional modules are needed beyond the power supply’s capacity, they must be installed in expansion or remote backplanes.

Fault Detection and Logging

Features built-in fault detection capabilities to ensure the continuous operation of the RX3i system. If an internal fault occurs, the power supply signals an alarm, which allows the CPU to detect a loss of power or log the appropriate fault code. This feature helps in quickly identifying issues and preventing prolonged system downtime.

LED Indicators

• Power (Green/Amber): A green LED indicates power is being supplied to the backplane. An amber LED indicates that power is applied to the power supply but the power supply switch is off.
• P/S Fault (Red): A red LED indicates that the power supply has failed and is no longer supplying sufficient voltage to the backplane.
• Over Temperature (Amber): An amber LED lights up when the power supply is near or exceeding its maximum operating temperature.
• Overload (Amber): This amber LED warns when the power supply is nearing or exceeding its maximum output capability on any of its outputs.
• If the P/S Fault LED lights up, it indicates a power supply failure, while the Overtemperature and Overload LEDs provide warnings of high temperature or high load conditions. The CPU Fault Table will also display a fault if any of these conditions occur, helping to pinpoint issues quickly.

On/Off Switch

Features an on/off switch located behind a door on the front of the module. This switch controls the operation of the power supply outputs, but it does not interrupt the line power. A projecting tab next to the switch helps prevent accidental operation, ensuring that the power supply is turned off only when intended.

Wiring Terminals

The power supply module includes wiring terminals for connecting the +24V and –24V power, ground, and MOV disconnect, which accept individual 14 to 22 AWG wires. These terminals make it easy to integrate the power supply into the overall system and ensure proper power distribution to all components.

Overcurrent Protection

• The power supply is designed with overcurrent protection mechanisms to safeguard the system from damage. The 5.1 VDC output is electronically limited to 7 Amps, and the 3.3 VDC output is limited to 10 Amps. If an overload or short circuit occurs, the power supply senses the issue and shuts down.
• It will continually attempt to restart until the overload condition is resolved. Additionally, an internal fuse provides backup protection, ensuring that the power supply can handle internal faults.
• The fuse typically blows only if the power supply has not shut down first. The CPU Fault Table will log any overcurrent, overload, or power supply fault events.
