RX7i Racks IC698CHS017: Rear (wall) mount, 17 slots IC698CHS217: Rear (wall) mount, 17 slots with rear I/O access IC698CHS117: Front mount, 17 slots IC698CHS009: Rear (wall) mount, 9 slots IC698CHS109: Front mount, 9 slots The RX7i rack can be used for all RX7i CPU and I/O configurations, including Series 90-70 I/O, and VME modules. The RX7i rack accommodates two module types: ■ RX7i and Series 90-70 modules, which use a detachable field wiring terminal board. Each I/O module accepts up to forty AWG #14 (2.10 mm2) wires. The wire bundle is routed out the bottom of the terminal board cavity where a cleat is provided for a tie wrap to secure the bundle to the terminal board housing. With the IC698CHS217, the VME64 J2 connector user -defined I/O pins are accessible through a rear 96-pin DIN connector. I/O wiring may be connected to these rear access connectors. If the optional rear cover is used, I/O wiring is routed out the bottom of the cover. ■ VME modules, which have varying methods of connecting to field devices. Backplane connectors are spaced on 0.8" (20.3mm) centers to accommodate single width and double width RX7i and non-GE Fanuc VME modules. The RX7i rack: ■ Accepts RX7i modules, VME modules, and some Series 90-70 modules. For a list of supported modules, refer to page 2-16. ■ Provides slot sensing for Series 90-70 rack-type I/O modules. No jumpers or DIP switches on the I/O modules are required for addressing of these modules. ■ Provides J2 backplane connectors to allow high-speed VME transfers of up to 64 data bits per cycle. ■ Accepts plug-in RX7i AC power supplies. ■ Supports an optional cooling fan assembly (required for IC698CPE020/CRE020/CPE040/CRE040, IC698PSA350, IC698PSD300, or any of the single-width IC697Vxx modules). ■ Provides a 6-pin RJ-11 connector for connecting an I2C serial cable. ■ The IC698CHS217 rack provides rear access to the VME64 J2 backplane connectors. The rack accepts a power supply in slot 0 and a CPU with Ethernet daughterboard in slots 1 and 2. The remaining slots can be used for one of the following I/O combinations.
