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
- Operates within a specified input voltage range of 18 VDC to 30 VDC, making it adaptable to various industrial power supply conditions. Ensures stable power delivery even in environments with slight voltage fluctuations.
- This module delivers three distinct output voltages, each serving specific functions within the RX3i system.
- +5.1 VDC Output: Powers essential system components such as the CPU, I/O modules, and communication modules. Ensures consistent voltage regulation to support reliable system performance.
- +24 VDC Relay Output: Specifically designed to power circuits on Output Relay Modules, ensuring seamless operation of control and switching devices.
- +3.3 VDC Output: Provides power for RX3i modules with IC695 catalog numbers, supporting various system functionalities.
- Only one power supply can be installed in a PACSystems RX3i Universal Backplane. This restriction ensures proper power distribution and prevents voltage conflicts within the system.
- Cannot be used in redundant or increased capacity modes with other RX3i power supplies. Attempting to use this power supply with another could result in system damage or failure. Designed for standalone operation, ensuring that power supply integrity is maintained.
- If the system requires additional modules beyond this power supply’s capacity, they must be installed on expansion or remote backplanes.
This design supports system scalability while maintaining operational stability.
Fault Detection and Logging
- Fault Detection Mechanism: The power supply is designed with advanced fault detection circuits that continuously monitor the internal health of the module. When an internal issue arises, such as an overvoltage, undervoltage, or power failure, the power supply module can immediately identify the fault. This detection mechanism is crucial in industrial environments, where continuous uptime is necessary for maintaining production and operations.
- Alarm Signaling for Quick Response: Once a fault is detected, the power supply module triggers an alarm signal. This alarm is communicated to the CPU of the RX3i system, notifying operators or system administrators that a power-related issue has occurred. The alarm system provides a quick and visible indication, allowing for a prompt response to identify and resolve the issue.
- Fault Code Logging: In addition to generating an alarm, also logs the relevant fault code in the system's memory. This allows the CPU to capture detailed information about the nature of the fault, which can be reviewed later. The logging feature ensures that operators have access to a historical record of power supply issues, aiding in troubleshooting and preventing recurring faults. Examples of faults that might be logged include Power supply overload, Voltage regulation failure, Short circuit detection, Overcurrent or under voltage conditions
- Prevention of Prolonged Downtime: By quickly detecting and signaling faults, the power supply module enables the system to take immediate corrective actions, such as switching to backup power sources or initiating a controlled shutdown. This prevents prolonged system downtime, ensuring that critical processes in industrial automation, manufacturing, or control systems are not disrupted.
- Early Issue Identification for Proactive Maintenance: The fault detection and logging capabilities of the module allow for proactive maintenance. By identifying issues early, operators can address potential failures before they lead to more severe system malfunctions. Regular analysis of logged fault codes can help operators optimize the performance and longevity of the power supply, reducing the likelihood of unplanned outages or costly repairs.
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.
