GE Fanuc IC697ACC722 Auxiliary Airflow Cooling Unit

Product Description

The IC697ACC722 is a high-efficiency auxiliary cooling fan assembly designed exclusively for GE Fanuc Series 90-70 PLC racks. In high-density automation environments where multiple high-speed processors and high-current I/O modules are co-located, thermal management is critical to preventing processor throttling and hardware degradation. The IC697ACC722 provides forced-air circulation to maintain internal rack temperatures within optimal operating limits, ensuring the longevity and reliability of the control system.

Engineered for continuous industrial operation, the IC697ACC722 features a dual-fan configuration that offers consistent airflow across the module fins and backplane. This assembly mounts directly to the Series 90-70 rack frame, drawing power from the system's AC supply to provide immediate thermal relief. As a critical maintenance component, it prevents localized hotspots that could otherwise lead to intermittent logic errors or total module failure. Note: While some technical databases list the IC697ACC722 under backplane connectors or jumper kits, the primary industrial application for this part number is the specialized rack cooling assembly.

Application & Maintenance Strategy

The IC697ACC722 is recommended for any Series 90-70 installation where ambient enclosure temperatures exceed 40 °C or where the rack is populated with power-intensive modules like the IC697CPX series CPUs. Regular maintenance involves inspecting the fan blades for dust accumulation and verifying that the bearings remain quiet. A seized fan in a sealed cabinet can quickly lead to an over-temperature trip, making the IC697ACC722 a vital part of proactive system health monitoring.

Frequently Asked Questions

Is the IC697ACC722 compatible with Series 90-30 or RX3i racks?

No, the IC697ACC722 is specifically sized and powered for the Series 90-70 VME-style racks. Newer RX3i systems utilize different cooling solutions (such as the IC695ACC series) designed for their specific rack dimensions.

Does the fan assembly require separate wiring?

The IC697ACC722 typically connects to the AC power terminal available on the rack's power supply or a dedicated auxiliary power tap within the cabinet, following the standard wiring practices for Series 90-70 cooling accessories.
