Overview
The 140XBP00600C is a Schneider Modicon Quantum automation platform rack backplane, order code 140XBP00600C, providing 6 free slots for local, distributed, or remote I/O modules in a Quantum system. It is surface-mounted, fixed by screw, and carries a conformal coating (Humiseal 1A33) for protection in harsh environments. The part has been discontinued by Schneider since 2021-12-31.
This backplane serves as the mechanical and electrical backbone for a Modicon Quantum I/O rack. Its 6 free slots accept any combination of local, distributed, or remote I/O modules — analog, discrete, or special-function — that snap onto the backplane and communicate over the Quantum bus. The conformal coating (Humiseal 1A33) protects the PCB from moisture, dust, and chemical exposure, making the rack suitable for installation in environments where uncoated backplanes would risk corrosion or tracking. Fixing is by screw to a surface mount, not DIN-rail.
Applications
Modicon Quantum backplanes of this class are used in medium-to-large process and discrete automation systems — water treatment, chemical processing, material handling, and machine control — where the rack holds I/O modules that interface with field sensors and actuators under a Quantum CPU.
