Product Overview
The 100% Brand New GE IC693CHS392K serves as a 10-slot expansion base for the Series 90-30 PLC system. It houses up to ten I/O or option modules and connects to the CPU baseplate via a 25-pin expansion cable. This baseplate extends the control system's I/O count without requiring a dedicated CPU in the remote rack, making it essential for distributed control architectures.

Engineering Advantages
-
Distributed I/O Deployment: The baseplate links to the main CPU rack using a 25-pin D-type cable for distances up to 50 feet. Engineers place I/O closer to field devices, which reduces long wire runs, lowers installation costs, and minimizes electrical noise on analog signals.
-
High-Density Modular Growth: The 10-slot capacity accommodates a mix of digital, analog, and communication modules. Technicians add this baseplate to scale the system from 4 to 7 total racks (depending on the CPU), allowing the PLC to grow with plant expansion without replacing the core controller.
-
Secure Panel Integration: The unit features mounting flanges for direct panel attachment. This rigid mounting secures the backplane against vibration in heavy industrial environments (e.g., near presses or compressors), ensuring the modules maintain positive contact with the bus connectors.
-
Simplified Addressing: A built-in DIP switch sets the rack ID (1-7). The CPU automatically recognizes the modules in this rack once the physical switch matches the software configuration, streamlining commissioning and troubleshooting.
FAQs
-
Can I install a CPU module in the IC693CHS392K?
No. This is strictly an expansion base. It does not contain a slot with the specific pinout required for a Series 90-30 CPU. You must use a CPU baseplate (like the IC693CHS391) for the rack holding the processor.
-
Does the IC693CHS392K require its own power supply?
Yes. You must install a Series 90-30 power supply module (e.g., IC693PWR321 or IC693PWR330) in the dedicated power supply slot of this baseplate to energize the backplane and the I/O modules.
-
What modules cannot go into this expansion base?
The IC693CHS392K does not support "Intelligent" option modules that handle complex bus mastering or specific communications (such as PCM, ADC, BEM330, or CMM modules). These modules require installation in the main CPU baseplate.
-
Is the "-K" revision interchangeable with older revisions (e.g., -J, -F)?
Yes. The IC693CHS392K functions as a direct electrical and mechanical replacement for previous revisions of the IC693CHS392. The suffix indicates manufacturing updates or component changes, but the form, fit, and function remain consistent.
