GE-FanucIC600CP620L/500Series Six Plus 11-Slot CPU Rack with Integral 115/230 VAC Power Supply, 19-Inch or Panel Mount, Max 7 I/O Slots

Product Description

What this part is

This is a GE Fanuc Series Six Plus CPU rack, catalogue number IC600CP620 — the 11-slot chassis that carries the processor end of a Series Six Plus programmable controller. It combines the rack, the backplane and an integral wide-range AC power supply in one assembly, and it is the item the rest of the control plugs into.

Getting the tier right matters here, because “programmable controller” is doing a lot of work in the old copy. IC600CP620 is the CPU rack, not a single plug-in processor card. If your fault is a dead processor board, you want an IC600CB or IC600LX-series module. If your rack has failed, its power supply has died, or you are building a control up from parts, this is the piece you want — and it brings the power supply with it, which is usually the expensive half.

Decoding the catalogue number

IC600 — the GE Fanuc Series Six family prefix.
CP — CPU rack / central processor chassis class, as distinct from CHS (I/O chassis), BF (plug-in functional and I/O boards), CB and LX (processor and memory boards) and RP (remote processors).
620 — the specific rack: 11 slots, 115–230 VAC integral supply.
L — hardware revision letter. Later letters supersede earlier ones within the 620 designation.
/500 — a build / configuration designation stamped on the unit alongside the catalogue number. Record it from the label when quoting the part to a repair house.

What these specs mean in practice

Eleven slots is not eleven slots of I/O. Four of them are committed to the processor and system boards, which is why the published figure is a maximum of seven for I/O modules. Plan the module schedule on seven, not eleven, or you will be buying an expansion chassis you did not budget for.

The 115–230 VAC, 47–63 Hz supply is the quietly valuable part of this assembly. It means the rack will take North American 120 V or European/industrial 230 V without a change of hardware, and it tolerates 50 and 60 Hz plants alike — useful on machinery that has moved country, and useful when a Series Six line is being kept alive on whatever supply the new building offers. Confirm the voltage-selection arrangement on the unit before energising rather than assuming.

Watch the slot rules and the 5 V budget. Series Six modules are slot-position sensitive and the rack’s card schedule matters; equally, the integral supply has a finite 5 V rail, so if you are filling the rack with high-density I/O and intelligent modules, add up the module current draws before you commit.

Quantity and configuration

One rack assembly ships. No processor or memory boards, no I/O modules, no battery, no field terminal blocks or wiring arms, no expansion or remote I/O chassis, no programming cable or software, and no manual are included unless visible in the photographs. Because a used CPU rack sometimes arrives with boards still fitted and sometimes bare, treat the photographs as the definitive statement of what is populated, and ask if anything is unclear.

Installation and setup notes

This is a 19-inch assembly that weighs roughly 37 lb when full — support it properly on installation and use the correct rack hardware; hanging a loaded Series Six rack off two screws is how backplanes crack. Isolate and lock out before wiring the supply, and confirm the input voltage selection matches your feed. Series Six modules are not hot-swappable: power down before inserting or removing anything, because a live insertion can corrupt the CPU’s memory as well as damage the card. Keep the rack’s ventilation path clear top and bottom to stay inside the 0–60 °C window; the supply is the part that suffers first in a hot cabinet. When the rack is open, clean and reseat the gold edge connectors on every board with isopropanol and a lint-free wipe — on a control of this age, intermittent faults are more often fretted contacts than failed silicon. Fit a fresh battery and verify program retention through a deliberate power cycle before releasing the machine.

Interchange guidance

Searched as IC600CP620L, IC600CP620, IC600CP620L/500, IC600CP620L500, IC600-CP620, IC600 CP620 L and Series Six Plus CPU rack 11 slot. Other revision letters of the same rack are the closest cross-references — the revision letter is the only difference within the 620 designation. Related Series Six part blocks worth knowing so you can rule them in or out: IC600CHS I/O chassis, IC600BF plug-in I/O and functional boards, IC600CB and IC600LX processor and memory boards (for example IC600LX612), and IC600RP remote processors such as IC600RP551. Brand and support history for search reach: GE Series Six, GE Fanuc Automation, GE Intelligent Platforms, now Emerson; the platform is long obsolete with no factory replacement, and Emerson’s migration path is PACSystems RX3i, which is a full control rebuild rather than a rack swap. That is why a good Series Six Plus CPU rack with a healthy power supply is worth stocking for a plant that still runs one.
