GE IC695ACC650 RX3i Conversion Rack for Series 90-70 Upgrade

Technical Specifications Breakdown

Key parameters for the IC695ACC650 are listed below for quick reference:

Industrial Applications for the Conversion Rack

Modernizing Aging Control Systems

Many facilities still rely on Series 90-70 PLCs for critical processes. The IC695ACC650 enables a phased migration to RX3i without replacing entire cabinets.

Reducing Downtime During Upgrades

By using this conversion rack, engineers can pre-assemble the RX3i components on the rack while the existing 90-70 system remains operational. The swap can then be executed in a single shift, drastically cutting production losses.

Supporting Flexible Enclosure Layouts

With support for 7-slot, 12-slot, and 16-slot backplanes, the rack adapts to various cabinet sizes. Both vertical and horizontal mounting options give engineers the freedom to optimize panel space without redesigning the layout.

Installation & Setup Guidance

Before mounting the IC695ACC650, ensure the terminal block assembly is removed as specified. Use the captive screws and tighten to the recommended torque of 2.5 Nm. The rack includes a slotted bracket for easier positioning. When connecting field wiring, attach the ground lug using a conductor no smaller than 12 AWG to ensure proper grounding. The rack can be mounted in either orientation, but always verify adequate clearance for airflow and LED visibility.

Maintenance & Reliability

The IC695ACC650 is constructed from materials suitable for harsh industrial environments. Periodically inspect the rack for dust accumulation and ensure ventilation paths remain clear. Verify that all mounting screws are secure and the ground connection is intact. No internal components require user servicing.

Seamless System Upgrade with the GE IC695ACC650 Conversion Rack

Upgrading from a legacy GE Series 90-70 to a modern RX3i PACSystems platform often involves significant downtime and rewiring. The IC695ACC650 conversion rack directly addresses this challenge by acting as a mechanical and electrical bridge, allowing you to reuse existing I/O and field wiring while migrating to a more powerful controller. This rack is specifically designed to minimize installation time and reduce the risk of errors during the transition.

Compatibility & Integration

This rack is designed to work with both the RX3i PACSystems and the existing Series 90-70 backplanes. It supports I/O adapter modules and can be connected to terminal block assemblies for field wiring. Optional adapter plates are available for additional mounting flexibility.

Selection Guide & Purchasing Advice

When planning your upgrade, verify that your current Series 90-70 backplane size matches one of the supported sizes (7, 12, or 16 slots). The IC695ACC650 is available from AutoDCSTech, a trusted supplier of industrial automation parts. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
