Products Description
Schneider 140XBP00400 Modicon Quantum 4-Slot Backplane
Schneider 140XBP00400 is a 4-slot rack backplane designed for Modicon Quantum PLC system. It provides electrical backplane bus and mechanical mounting base, enabling power supply, CPU and I/O modules to exchange data and power through internal bus traces.

This passive backplane supports hot-swap of Quantum series plug-in modules. It adopts high-reliability gold-plated connectors for stable signal transmission, and features a sturdy metal frame for cabinet installation. As aftermarket spare parts, it is widely used for maintenance, replacement and retrofit of small-scale Modicon Quantum PLC control cabinets.

Core Functions
- Offer 4 mechanical slots for installing Quantum power supply, CPU and I/O modules, fixing all modules firmly inside the control cabinet.
- Internal bus traces transmit DC power and high-speed communication signals among all modules mounted on the backplane.
- Gold-plated connectors reduce contact resistance and prevent oxidation, maintaining stable electrical connection under vibration and temperature variation.
- Passive circuit design without active chips, low failure rate and supports hot-swap operation of individual modules without damaging the whole rack.
- Standard mounting structure allows easy installation in industrial control cabinets for small automation control projects.
- Good EMC shielding performance reduces electromagnetic interference impact on bus signal transmission in industrial environments.
Application Scenarios
- Small PLC rack base for Modicon Quantum automation systems used in factory production lines, water treatment and small process control projects.
- Fault backplane replacement and routine maintenance of existing 4-slot Quantum PLC control racks.
- PLC rack hardware upgrading and technical transformation for small-scale legacy Modicon Quantum automation control systems.
- Emergency swap for backplane connector failure of small automation equipment using Quantum PLC control.
- Spare-parts stocking for electrical and automation maintenance teams supporting Schneider Modicon Quantum series products.
- Aftermarket spare supply for small PLC control cabinet overhaul and technical-service projects of industrial automation facilities.
FAQ
- Q: Can Schneider 140XBP00400 work independently without Quantum power supply, CPU and I/O modules?
A: It is a passive rack base, must be equipped with matched Quantum modules, cannot run as standalone hardware. - Q: What are typical backplane failure symptoms?
A: Intermittent module offline, unstable bus communication, module power loss, poor contact caused by connector oxidation. - Q: How to complete commissioning and diagnosis?
A: Inspect connector pins for damage and oxidation; install modules and test bus communication and power distribution of each slot.
