The GE Fanuc IC697CHS790 is a professional 9-slot rear-mounted chassis engineered for the Series 90-70 PLC system. It features a 20A VME-compliant backplane that facilitates seamless module communication and power distribution, while supporting optional fan assemblies for enhanced thermal regulation in industrial environments.
The GE Fanuc IC697CHS790 functions as a high-capacity backplane and the fundamental mounting framework for the Series 90-70 Programmable Logic Controller (PLC) ecosystem. This chassis establishes a robust electrical interface, which enables various IC697 modules to communicate with the central processing unit while drawing essential system power. Since the design utilizes a VME-compliant backplane, it consistently ensures high-speed data transfer and maintains reliable signal integrity across all nine available slots.
Engineers frequently select the IC697CHS790 when a project requires a precise balance between expansion capability and spatial efficiency. While the rack includes a dedicated section for the power supply module, the remaining slots house I/O modules, processors, or communication interfaces. In addition to housing these components, the backplane incorporates four specific jumpers. These jumpers allow the user to define a unique rack ID within a larger PLC network, thereby simplifying system addressing.
Furthermore, this chassis supports power supply extension configurations to enhance versatility. By utilizing the IC697CBL700 cable kit, a single power source can effectively energize two separate racks. Consequently, this configuration reduces hardware costs and significantly simplifies complex wiring layouts.
To maintain optimal performance in high-density installations, the IC697CHS790 offers compatibility with optional forced-air cooling. Users can integrate the IC697ACC721 (120 VAC) or IC697ACC724 (240 VAC) fan assemblies directly onto the frame. As a result, the system effectively mitigates heat accumulation during continuous operation. Additionally, the mechanical architecture includes specialized interlocking mechanisms. These features prevent the accidental insertion or removal of modules while the system remains under load, which protects the hardware from electrical damage. Moreover, the chassis features integrated grounding points to shield sensitive electronics from industrial electromagnetic interference.
