The IC698CHS117C is GE Fanuc’s 17‑slot, front‑mount (panel‑mount) rack with cooling fans for PACSystems RX7i / Series 90‑70 systems. It’s the “117” family’s high‑capacity chassis, with the “C” indicating a later hardware revision.Function and application

Role: Provides the backplane, mechanical structure, and power distribution for up to 17 modules (CPU, power supply, digital/analog I/O, communications, motion, VME cards, etc.) in large RX7i systems.

Platform: Compatible with RX7i CPUs, Series 90‑70 I/O, and many VME modules.

Mounting style: Front‑mount (panel‑mount) rack, typically installed in 19‑inch class cabinets with modules accessed from the front; includes integrated cooling fans for higher thermal loads.

Key specifications (typical for IC698CHS117 / 117C)

From GE documentation and distributor data:

Slots: 17 universal slots (VME‑style, 0.8 in / 20.3 mm pitch)

Backplane: VME64‑compatible bus supporting high‑speed module‑to‑module communication

Mounting: Front (panel) mount; designed for cabinet installation with front access

Cooling: Equipped with cooling fans to support high‑density, high‑power configurations (e.g., multiple high‑current I/O and large CPUs).

Power compatibility: Supports high‑wattage RX7i power supplies (e.g., 350 W class) and RX7i AC power plug‑in modules; backplane power distribution typically includes separate logic and I/O planes.

Environmental (typical):

Operating temperature: roughly 0 °C to 55 °C (some docs cite up to 60 °C)

Humidity: up to 95 % non‑condensing

Protection class: IP20 (metal enclosure) in standard industrial form

Certifications: Commonly listed with industrial approvals (UL/CSA/CE type) depending on configuration and region.

What the “C” suffix means

As with other GE Fanuc part numbers, the trailing letter (A, B, C, …) indicates a hardware revision (e.g., updated backplane layout, fan arrangement, connectors, or compliance markings) while preserving the same basic form factor and slot count.

In practice, IC698CHS117, 117A, 117B, and 117C are treated as interchangeable 17‑slot front‑mount RX7i racks for most system designs; the “C” mainly matters for exact revision control, spare‑part matching, and documentation.
