Get now IC693CHS397 GE Fanuc Series 90-30 Expansion Baseplate
Get now IC693CHS397 to significantly scale your industrial automation architecture without compromising backplane communication speed. The GE Fanuc IC693CHS397 is an industrial-grade 10-Slot Expansion Baseplate designed exclusively for the proven Series 90-30 Programmable Logic Controller (PLC) family. As your manufacturing processes grow and require additional sensing and actuation points, this expansion chassis allows you to seamlessly integrate up to 10 additional I/O or specialty modules into your existing control network. Unlike a standard CPU baseplate, the IC693CHS397 does not house a central processor; instead, it utilizes a dedicated 25-pin D-shell expansion connector located at the right end of the backplane to link directly to the primary CPU rack or another expansion baseplate in a daisy-chain topology. Built to withstand the harsh mechanical vibrations, electrical noise, and thermal stress typical of heavy industrial environments, this genuine OEM chassis ensures that your critical I/O data is transmitted with absolute deterministic reliability. Securing this hardware is the most cost-effective method to multiply your machine’s capabilities while retaining your validated logic programs.

Expert Installation and Rack Expansion Advice
When incorporating the IC693CHS397 into your control panel, strict adherence to the Series 90-30 expansion guidelines is mandatory. The maximum allowable cable length from the primary CPU baseplate to the final expansion baseplate in the chain is exactly 15 meters (50 feet). Exceeding this physical cable limit will result in severe signal attenuation, leading to intermittent I/O dropouts and fatal CPU backplane parity errors. When mounting the chassis, you must leave adequate vertical clearance—at least 6 inches above and below the rack—to ensure proper convective cooling for the power supply and high-density output modules. Furthermore, always verify that the grounding strap on the baseplate is securely bonded to the main cabinet ground. This prevents high-frequency electromagnetic interference (EMI) from corrupting the delicate 5 VDC logic signals traveling across the backplane.
Frequently Asked Questions (FAQs)
Can I install a CPU module in the IC693CHS397 baseplate? No. The IC693CHS397 is strictly an expansion baseplate and lacks the necessary backplane circuitry to support a Central Processing Unit. If you need a rack to house a CPU, you must utilize a CPU baseplate such as the IC693CHS391.
Does this expansion rack require its own power supply? Yes. The expansion cable only transmits data signals, not power. You must install a compatible Series 90-30 power supply module (such as the IC693PWR321) in the dedicated leftmost slot to provide the 5 VDC and 24 VDC power required by the modules residing in this specific chassis.
How many expansion baseplates can be connected together? Depending on the specific CPU model installed in your primary rack, a Series 90-30 system can typically support up to a maximum of 7 expansion or remote baseplates daisy-chained together, adhering to the strict 15-meter total cable length limit.
