Overview
The 140XBP01600C is a Schneider Modicon Quantum automation platform rack backplane, order code 140XBP01600C, providing 16 free slots for I/O modules in a Quantum control system. It is a passive backplane — no active electronics — that distributes power and data bus signals to the modules seated in its slots. The unit is surface-mounted with screw fixing and carries a conformal coating (Humiseal 1A33) for protection in mildly corrosive environments. It is supplied as a single PCE package.
As the mechanical and electrical backbone of a Quantum I/O rack, the 140XBP01600C backplane provides the slot connectors and bus traces that link the power supply, CPU, and I/O modules. The 16 free slots accommodate any combination of local, remote, or distributed I/O modules (analog, discrete, special-function) as long as the total power draw stays within the rack power supply rating. The backplane itself has no addressing or configuration — it is a passive interconnect. Slot numbering is fixed; modules are addressed by their physical position. The conformal coating adds a layer of protection against condensation and airborne contaminants, which matters in non-conditioned cabinets or washdown zones.
Applications
This 16-slot backplane is used within the Modicon Quantum automation platform for medium-to-large control systems in industries such as water and wastewater, oil and gas, chemical processing, and material handling. It hosts the CPU and I/O modules that execute machine and process logic, typically in a central control cabinet with remote I/O drops connected via fieldbus.
The 140XBP01600C is the 16-slot backplane in the Quantum platform.
The 140XBP01600C was officially discontinued by Schneider as of 2021-12-31. It is no longer in active production and has no direct replacement from the manufacturer. Buyers needing this exact backplane for an existing Quantum system must source from surplus, broker, or aftermarket channels. The conformal-coated variant is less common than the standard version, so availability may be tighter.
