Description

The GE Fanuc IC694PWR330 is a high-performance power supply module designed for the RX3i PacSystem backplane. It provides reliable voltage regulation and power distribution, converting high-voltage inputs into stable logic-level currents required for system operation. Engineered for demanding industrial environments, this module ensures consistent performance in sectors such as power generation, oil and gas, and heavy manufacturing. It features a 20 ms hold-up time to maintain controller operation during brief power sags or grid fluctuations, preventing unnecessary system resets.

Features

• Universal input range supporting 85 to 264 VAC or 100 to 300 VDC.
• Integrated 24 VDC auxiliary output loop (up to 20 W) for powering external field instrumentation.
• Galvanic isolation of 1500 VAC to protect the backplane logic bus from field-side electrical transients.
• Built-in overvoltage and overcurrent protection circuits for enhanced system safety.
• Front-panel LED diagnostics (PWR, OK, RUN) for real-time status monitoring.

Technical Specifications

Installation Guidelines

• Ensure the system power is disconnected before installing or removing the module from the RX3i rack.
• Seat the module firmly into the backplane slot and secure the mounting screws to ensure proper grounding and mechanical stability.
• Use appropriate wire gauges for power connections and tighten terminal screws to a torque of 1.3 N-m.
• Maintain adequate clearance around the module to allow for proper airflow and cooling.
• Avoid routing high-voltage power cables in the same conduits as low-voltage signal or communication wiring to minimize EMI.

FAQ

Does this module support both AC and DC input power?

Yes, the IC694PWR330 is designed to accept a wide range of inputs, specifically 85 to 264 VAC or 100 to 300 VDC.

What is the purpose of the auxiliary output?

The module provides an isolated 24 VDC output rated at 20 W, which is intended to power external field devices or instrumentation directly from the power supply.

How do I monitor the status of the power supply?

The module features three front-facing LED indicators: PWR (Power), OK (Module Health), and RUN (PLC Execution State), which provide immediate visual feedback on the operational status.
