GE Fanuc IC694PWR330 PACSystems RX3i Power Supply Module

The GE Fanuc IC694PWR330, also cataloged as the IC694PWR330 Remote Base Power Supply, operates as a dedicated hardware component for localized voltage conversion within PACSystems RX3i expansion networks. Configured to mount directly on remote I/O chassis, the module converts incoming AC or DC line power into a regulated 5.1 VDC supply to drive internal backplane logic and low-power bus transceivers. It prevents electrical sag by establishing isolated power boundaries for remote infrastructure distinct from the main controller rack.

Hardware Specifications

Backplane Bus Communication Velocity and Deterministic Networks

The IC694PWR330 maintains regulated electrical potentials required to preserve backplane bus communication velocity across high-density remote chassis. By stabilizing the 5.1 VDC rail, the hardware ensures that expansion bus transmitters can maintain transmission rates without jitter or bit dropouts. This voltage stability is required when streaming cyclic I/O data through network links connected to Profinet or EtherNet/IP deterministic networks, ensuring that firmware flash operations and module-to-module synchronization signals remain within specified clock boundaries.

Frequently Asked Questions

Q: Can this module be installed in a main PACSystems RX3i Universal Backplane next to the primary CPU?

A: No. The IC694PWR330 is specifically engineered and keyed for Remote/Expansion Bases only. Main slots requiring higher wattage parameters must utilize modules such as the IC695PSA140, as the expansion bus power distribution circuitry differs from the primary PCI controller chassis.

Q: Does the IC694PWR330 provide diagnostic status registers to the host controller over the backplane?

A: Yes. The module monitors input voltage status and internal thermal limits. If the input power drops below the minimum specified operational range or internal power conversion thresholds are exceeded, the module signals a fault condition across the backplane to execute a controlled safe shutdown sequence before power loss occurs.

Field Installation Guidelines

• Chassis Integration: Ensure all incoming power lines are completely de-energized prior to slot engagement. Slide the module housing straight into the leftmost slot of the designated remote expansion rack, ensuring that the rear multi-pin connector seats firmly into the backplane before securing the mechanical frame screws.
• Conductor Layout: Route incoming 120/240 VAC or 125 VDC field lines through independent conduit pathways away from low-voltage communication or analog signal cables. Maintain a minimum distance to prevent capacitive coupling and electromagnetic interference.
• Ground Termination: Wire the external ground lug on the faceplate directly to the system enclosure plate or master copper ground bus bar using a short, low-impedance conductor. Do not daisy-chain the ground connection across multiple modules.
• Load Calculation: Total power consumption of all populated I/O modules on the expansion backplane must be tallied prior to commissioning to ensure the cumulative 5.1 VDC draw does not exceed the 30 W physical hardware limit.
