IC697CHS790D is a hardware revision rack of version D of IC697CHS790, GE Fanuc Series90‑70， 9-slot rear ordinary rack, D represents the revised version of the backplane hardware, with electrical functions and dimensions basically the same as the IC697CHS790 basic version, optimized backplane circuits, and better compatibility with new firmware modules. It is still a single VME backplane, non redundant rack, and cannot be used for dual CPU hot standby redundant systems. The rack body does not include control electronic boards and is composed of a metal shell and a standard VME backplane, used for installing CPU, I/O, communication, and coprocessor modules.

The whole machine has a total of 10 slots, including 1 independent power slot and 9 universal module slots. The backplane complies with the VME bus specification, with a slot spacing of 0.8 inches, compatible with all IC697 series modules and compliant third-party VME boards. Backboard 5VDC maximum output current of 20 amperes, compatible with IC697PWR series AC and DC power modules. The D-version rack hardware has modified the fan installation interface to directly adapt to later versions of fan components IC697ACC721B, 724B, and 744. The old version CHS790 is not directly compatible with the later version fan kit Qualitrol of this series.

The installation form is rear mounted Rear Mount, with the flange on the back of the rack and the module inserted from the back of the cabinet, suitable for standard 19 inch industrial cabinets. Physical dimensions: height 283mm, width 483mm, depth 190mm; overall weight approximately 3.6kg.

A 4-digit rack ID jumper is set behind the power slot, and multi rack systems are used to set rack numbers 0-7. The CPU rack is fixed to rack 0 by default. Support external expansion of racks through expansion cables, support up to 2 racks sharing power supply driven by a single power source, and achieve I/O scale expansion. The rack is equipped with module anti error mechanical locks, and different types of modules have positioning buckles to prevent incorrect insertion. The module supports hot swapping and can be replaced during operation without interrupting system operation.

Environmental conditions: working temperature 0-60 ℃, storage temperature 40-85 ℃, relative humidity 5-95%, no condensation, meets industrial vibration and impact standards, and has UL certification.
