Functional Description

IC693PWR331D is an expandable high-capacity power supply Module developed by GE Fanuc. It is a high-capacity power supply designed for the Series 90-30 programmable logic controller (PLC) systems. Known for its reliability and versatility, this unit is optimized for providing stable and consistent power to various PLC modules and external devices within industrial automation systems.

Power Specifications

Operates with a nominal input voltage of 24 VDC and offers a wide input voltage range from 2 VDC to 30 VDC. It is equipped with a robust 30-watt power rating, ensuring it can handle significant power demands. The power supply features three distinct outputs:

• +5 VDC Output: Designed for applications requiring a stable +5VDC, this output supports higher current capacities than standard supplies.
• +24 VDC Relay Power Output: This output is dedicated to powering the Series 90-30 Output Relay module circuits, essential for controlling external devices.
• Isolated +24 VDC Output: Typically used internally by various PLC modules, it can also supply external power to 24 VDC input modules, providing isolation to prevent signal interference.

Power Calculation and Application

• Determine Power Requirements: Identify the total power load of each module in the system, as detailed in the Installation Manual for the IC693 PLC series.
• Calculate Input Power: Multiply the total output power load by 1.5 to account for potential losses and ensure adequate power supply. For example, a 20-watt output power load would require 30 watts of input power.
• Consider Start-Up Surge and Margins: Account for start-up surge current and add a 10-20 percent margin to your calculations to ensure reliable performance under varying conditions.

Practical Considerations

• The design allows it to maintain output specifications even at low input voltages, making it suitable for diverse industrial environments.
• Its flexibility in output options and high current capacity make it an integral component in complex PLC systems, ensuring that power management is both effective and reliable.

Field Wiring Connections to the DC Input-Only Power Supplies

DC Power Source Connections

The field wiring for the DC Input-Only Power Supplies begins with connecting the + and - wires from the DC power source to the terminal strip of the power supply. Specifically, the + wire is connected to the top terminal screw, while the - wire is connected to the second screw from the top, ensuring proper polarity. A ground connection should then be made by attaching it to the third screw on the terminal strip. This clear and straightforward wiring scheme is typically marked on the front of the power supply, helping users easily identify the correct terminals for each connection.

Isolated 24 VDC Supply Output Connections

The Isolated 24 VDC Output is available through the bottom two terminals of the power supply's terminal strip. These terminals provide the +24V DC output, which can be used to supply power to external circuits. However, it is important to note that the current draw for any connected external circuits must be within the power limitations of the supply to prevent overloading and ensure proper functioning. This output is isolated, meaning it is electrically separated from the input side, providing additional protection and flexibility for use with sensitive external equipment.
