Description

The General Electric IC693PWR330 is a high-capacity power supply module designed for the Series 90-30 Programmable Logic Controller (PLC) family. This module is engineered to provide reliable backplane power for PLC racks, offering a 30-watt load capacity. Unlike standard power supply models, the IC693PWR330 allows the full 30-watt capacity to be allocated to the +5VDC output, making it suitable for larger rack configurations that require higher current capacity for connected I/O modules.

Features

• High-capacity 30-watt output with full allocation capability for +5VDC.
• Auto-ranging input voltage eliminates the need for manual jumper settings.
• Integrated current limiting protection to prevent hardware damage during short circuits.
• Built-in smart switch fusing for enhanced safety.
• Includes an RS-485 serial port for connection to programming devices or workstations.
• Advanced diagnostics integrated with CPU performance monitoring.

Technical Specifications

Installation Guidelines

• The module must be installed in the leftmost slot of the Series 90-30 baseplate.
• Ensure the system power is disconnected before inserting or removing the module to prevent electrical arcing or damage to the backplane.
• The module utilizes a snap-in design similar to standard I/O modules; ensure it is fully seated and secured.
• Maintain adequate ventilation around the PLC rack to prevent overheating during operation.
• Ensure proper grounding of the PLC rack system to mitigate EMI and ensure stable operation of the RS-485 serial port.

FAQ

What is the primary difference between the IC693PWR330 and the IC693PWR321?

The IC693PWR330 is a high-capacity power supply, whereas the IC693PWR321 is a standard model. While both provide 30 watts of total power, the IC693PWR330 allows the entire 30 watts to be utilized by the +5VDC output, providing greater flexibility for larger systems.

What is the purpose of the RS-485 port on this power supply?

The RS-485 port allows for direct communication with programming devices, such as a laptop, desktop workstation, or a GE Fanuc Hand-Held programmer.

How does the overvoltage protection work?

The module features internal protection circuitry that triggers if the 5VDC output exceeds 6.4 to 7 volts, shielding the internal components and connected modules from voltage spikes.
