General Electric IC693PWR331 Power Module Fanuc PLC I/O Modules 50W 18-30VDC High Capacity

 General Electric IC693PWR331 Power Module Fanuc PLC I/O Modules 50W 18-30VDC

I. Product Overview
The IC693PWR331 is a high-capacity DC power supply module designed by GE Fanuc (now Emerson) for the Series 90-30 PLC platform. It converts 18–30 VDC field power into the three regulated outputs required by the PLC: +5 VDC, +24 VDC Relay, and +24 VDC Isolated. With a total power output of 30 W, it can directly power the CPU, I/O, and communication modules. It is a key power supply component for upgrading older production lines, replacing spare parts, and integrating OEM systems.

II. Key Selling Points
• High power density: 30 W total output, with the entire 30 W available on the +5 VDC output, meeting the needs of high-point I/O or high-speed processors.
• Wide input range: 18–30 VDC (18 VDC startup, 12–30 VDC operation), compatible with batteries, switching power supplies, and solar DC bus.
• Independent protection for three outputs: +5 VDC 6.4–7 V overvoltage and 7 A overcurrent protection; +24 V dual overload recovery.
• 10 ms typical holdup time ensures no shutdown during transient grid drops.
• RS-485 diagnostic port provides real-time readings of voltage, current, and temperature, supporting remote preventive maintenance.
• UL and CE certified, -20°C to 60°C industrial-grade operating temperature, and 5 g vibration resistance for rugged environments.

IV. Typical Applications
• Automotive soldering line: Provides a centralized 5 V power supply for the IC693, CPU364, and numerous digital I/O devices
• Food and Beverage Canning: 24V output directly drives solenoid valves and photoelectric sensors, reducing external switching power supplies.
• Wastewater Treatment: The DC bus is powered by a UPS, and the IC693PWR331 ensures PLC online monitoring without downtime.
• Retrofitting of Old Equipment: Directly replace discontinued models such as the IC693PWR321, eliminating the need for cabinet modifications.
