1. Product Overview

2. Core Electrical Parameters

• Input power: External rack power source feeds +5VDC, +24VDC onto backplane copper busbar

• Power distribution: Uniformly output regulated +5V and +24V to every single module slot on backplane

• Internal bus: Embedded Ovation proprietary Multibus parallel communication trace for controller & I/O data exchange

• Max load capacity: Matches standard full slot configuration load of Ovation single rack

• Isolation design: Power circuit and signal bus separated layout, built-in surge absorption against cabinet transient interference

3. Mechanical & Environmental Spec

• Slot layout: Standard Ovation single-row slot structure for plug-in Eurocard modules

• Operating temperature: 0℃ ~ +60℃ (cabinet ambient); storage temperature: -40℃ ~ +85℃

• PCB treatment: Full conformal coating for anti-moisture, anti-salt fog, anti-mold to adapt power plant humid cabinet environment

• Compliance: IEC61000 EMC industrial anti-interference standard

4. Installation & Application Feature

1. Fixed mounted inside Ovation metal cabinet rack; all I/O cards plug directly onto its front slot

2. Unified bus routing eliminates scattered internal wiring between modules; simplifies cabinet field wiring

3. Support hot-swap of individual I/O modules without removing backplane or cutting entire rack power

4. Critical control racks adopt redundant dual power feed on backplane for uninterrupted power distribution

5. Common Troubleshooting

1. All modules on rack power off: External incoming power failure or backplane main bus open circuit

2. Individual slot no power output: Local slot power trace burnout or loose terminal connection

3. Partial modules communication loss: Partial Multibus track damage on backplane PCB
