Slot Configuration and Layout

The Schneider 140XBP00200 gives you two positions for Quantum 140 series modules. Slot 1 typically holds the power supply unit for the entire rack. Slot 2 accepts a CPU, I/O, or communication module. This compact layout suits small control systems with minimal I/O requirements.

Bus Communication Design

The internal backplane bus operates at a fixed 32 Mbps for deterministic scan times. This high-speed bus transfers I/O status and configuration data without user programming. Consequently, you can mix different module types freely across both slots. The bus auto-configures itself when you power up the system.

Installation and Mounting

You can mount this backplane horizontally or vertically inside your control cabinet. Four metal mounting tabs provide secure attachment to DIN rail or a subpanel. For best results, mount the unit on a flat, grounded metal surface. Leave 4 cm of clearance on all sides for cable routing and airflow.

Compatibility and Module Support

This backplane accepts all Quantum 140 series power supplies and CPUs. It also supports 140 series discrete I/O, analog I/O, and communication modules. You cannot mix older TSX or Premium series modules with this backplane. Therefore, plan your system architecture using only Quantum 140 components.

Physical Design and Construction

The FR4 PCB material provides excellent mechanical strength and electrical insulation. Thick copper traces carry power and data signals between module slots reliably. Tin-plated contacts resist corrosion and maintain good electrical connections over time. The 0.42 kg weight provides stable mounting without stressing cabinet walls.

Power Distribution

The backplane distributes +5 VDC and +24 VDC power to both installed modules. All power comes from the supply module in slot 1 exclusively. No external power wiring goes to the backplane itself. For best results, use a dedicated 24 VDC supply for field I/O power.

Why Choose This Backplane

This 2-slot backplane fits perfectly into extremely compact control applications. It supports the full range of Quantum 140 series modules for system flexibility. Therefore, choose this unit for small remote I/O drops, standalone controllers, and test stands.
