Introduction to the IC693PWR330 Power Supply
When a Series 90-30 PLC rack needs more +5 VDC current than a standard supply can provide, the GE Fanuc IC693PWR330 steps in. This high-capacity power supply delivers up to 30 Watts on the +5 VDC output, making it ideal for larger racks with many modules. As a maintenance engineer, I appreciate how this unit simplifies power distribution while keeping the backplane stable.
The IC693PWR330 is part of the Series 90-30 PLC family and is designed for the leftmost slot of the rack. It provides backplane power to attached modules, ensuring they operate reliably. With three outputs and a robust input range, it suits various industrial environments.
Key Technical Specifications
Understanding the IC693PWR330's specifications is crucial for proper integration. Here are the essential parameters:
- Input Voltage Range, AC: 85 to 264 VAC
- Input Voltage Range, DC: 100 to 300 VDC
- Nominal Rated Voltage: 120/240 VAC or 125 VDC
- Output Power: 5 VDC: 30 Watts max; 24 VDC Relay: 15 Watts max; 24 VDC Isolated: 20 Watts max
- Output Voltage: 5 VDC: 5.0 to 5.2 VDC (5.1 VDC nominal); Relay 24 VDC: 24 to 28 VDC; Isolated 24 VDC: 21.5 to 28 VDC
- Holdup Time: 20 milliseconds, minimum
- Inrush Current: 4A peak, 250 milliseconds maximum
- Input Power: 90 VA with VAC Input; 50 W with VDC Input
- Protective Limits: Overvoltage and overcurrent for 5 VDC output
- Standards: CE, UL
- Number of Connection Terminals: 6
These specs show the IC693PWR330's flexibility. It accepts both AC and DC inputs, making it adaptable to different plant power systems. The multiple outputs allow it to power logic, relay, and isolated circuits simultaneously.
Applications and Use Cases
In a typical packaging line, the IC693PWR330 powers a Series 90-30 PLC that controls conveyor motors and sensors. The +5 VDC output handles the processor and high-speed input modules, while the +24 VDC relay output drives output relay modules. This separation prevents noise from relay switching from affecting logic circuits.
Another common application is in material handling systems where the PLC must handle many I/O points. The IC693PWR330's 30 Watts on +5 VDC supports larger racks with multiple communication modules. The isolated +24 VDC output can also power external 24 VDC input cards, simplifying wiring.

From a maintenance perspective, the LED indicators are invaluable. The PWR LED shows if external power is sufficient, the OK LED indicates overall status, and the RUN and BATT LEDs monitor operation and battery charge. These indicators help technicians quickly diagnose issues without needing a multimeter.
Integration and Communication
The IC693PWR330 includes an embedded RS485 communication port. This port connects to a desktop or laptop workstation, a GE Fanuc Hand-Held programmer, or other compatible serial devices. For maintenance engineers, this allows easy programming and diagnostics without opening the cabinet.
When connecting AC power, use the top three terminals for hot, neutral, and ground (L1, L2, and ground for 240 VAC). For DC power, connect the positive and negative wires to the top two terminals, respecting polarity. The unit has six terminals total, providing clear connection points.
Maintenance and Reliability Tips
To ensure long service life, inspect the IC693PWR330 periodically for dust buildup and loose connections. Check that the input voltage stays within the specified range of 85 to 264 VAC or 100 to 300 VDC. Verify that the total load on all outputs does not exceed the combined 30 Watts capacity.
Monitor the LED indicators during routine checks. If the OK LED is off, investigate the load and input power. The overvoltage and overcurrent protection on the 5 VDC output helps prevent damage, but avoid exceeding the maximum ratings.

Since the IC693PWR330 is discontinued, verify availability and lifecycle status with BluePLC Industrial before ordering. They can provide guidance on replacements or continued support.
