Yaskawa Electric Corporation JZNC-XRK01B-1 Rack Backplane

The Yaskawa JZNC-XRK01B-1 Rack Backplane is a 3-slot PLC rack designed to be the structural and electrical backbone of Yaskawa CNC and robotic control systems, providing mounting, signal interconnection, and power distribution for CPU boards such as XCP01/XCP02, CPS power supplies, and interface cards. It is built for Yaskawa YASNAC and Motoman controller platforms and is rack-mounted inside control cabinets to enable coordinated control of motion, logic, and communication while reducing wiring complexity. Technical specifications include a ~200–230VAC, 50/60Hz input, a weight of about 5–5.4 lb, and a 3-slot configuration, identifying it as a legacy, used/refurbished component intended for maintenance or replacement in legacy systems. Common applications span CNC machines, industrial robots, and automated manufacturing systems where it houses CPU, I/O, and power modules to streamline module interconnectivity. Common replacements include JZNC-XRK01B CPU Rack (earlier revision), JZNC-NRK51-1, and JANCD-XBB01.
