Description
GE Fanuc IC693PCM301K Programmable Coprocessor Module Series 90-30 PLC 192KB
The GE Fanuc IC693PCM301K is a Programmable Coprocessor Module (PCM) designed for the Series 90-30 PLC rack system. It houses an onboard Intel 80188 processor and 192KB of user RAM, allowing it to run independent application programs — typically written in C or assembly — in parallel with the host CPU. This offloads computationally intensive tasks from the main PLC processor, enabling faster custom math, motion calculations, or specialized communication routines without impacting the main scan cycle.

Applications
The Series 90-30 is GE Fanuc's (now GE Automation & Controls / Emerson) mid-range modular PLC platform, widely deployed across manufacturing, water/wastewater, packaging, and process industries from the late 1980s onward. The IC693PCM301K coprocessor module is used in Series 90-30 systems where the main CPU needs supplemental processing power — for example, running real-time closed-loop control algorithms, handling custom serial communication protocols, or executing high-speed data logging routines. The PCM communicates with the main CPU through shared backplane memory, making it a common choice for machine builders and integrators who need deterministic, high-speed computation that would otherwise burden the main scan cycle. Many Series 90-30 installations remain in active service in legacy factory automation and utility control systems, and replacement or spare coprocessor modules like this one are regularly sought for system maintenance and repair.
This GE Fanuc IC693PCM301K Programmable Coprocessor Module has been inspected and appears to be in good used condition. It was pulled from a working industrial environment where it was previously in service. The housing is intact and the backplane connector and front label are in good shape with normal handling wear consistent with a used module.
