Yaskawa Electric Corporation JRMSI-BI026 Mount Base

The Yaskawa JRMSI-BI026 Mount Base is a multi-slot PLC chassis module for the MEMOCON-SCR84H backplane, delivering mounting support and backplane signal distribution for control modules in industrial automation. Built by Yaskawa, this mount base functions as a PLC chassis that accommodates CPU, I/O, and communication modules within a compact, multi-slot configuration and is installed in control cabinets or rack-mounted layouts. It is commonly used in MEMOCON control systems, CNC machines, and automation panels to organize modular components and enable scalable system expansion or replacement. The unit features an industrial PCB backplane with a mounting frame to support modular modules and route power and signals between them in manufacturing, process control, and automation environments. Note that the JRMSI-BI026 is listed as discontinued (legacy MEMOCON platform), with typical availability limited to surplus, refurbished, or used units. Common replacements include Yaskawa JRMSI-MB20 Memocon Mount Base and JRMSI-120XBP01000 GL120 Chassis Module, as well as the Siemens S7 Rack Backplane Module. For reference, the product details designate the part number JRMSI-BI026, the brand Yaskawa, and the system compatibility as MEMOCON-SCR84H series, underscoring its role as a dedicated mounting base and backplane distributor within PLC systems.
