Functional Features Multi-slot structure supports installation of multiple monitoring modules in one rack. Internal power traces distribute regulated DC power to each module slot. Impedance-controlled signal traces realize stable bus communication between modules. Gold-plated slot connectors guarantee reliable electrical contact under vibration. Built-in relay signal routing traces transmit alarm contact signals to rack terminal ports. Mechanical reinforcement structure improves rack rigidity against vibration.
Application Scenarios Machinery protection cabinets for turbines, compressors and large rotating equipment in power, petrochemical and oil & gas industries. It acts as the core backplane carrier for vibration and shaft position monitoring modules.
Performance Parameters
- Power distribution traces keep stable voltage supply for all modules in full temperature range
- Signal traces maintain low signal attenuation for monitoring data communication
- Gold-plated connectors keep stable contact performance under long-term vibration
- Mechanical structure withstands continuous low-frequency vibration without loose contact
Material Composition Base frame adopts high-strength metal alloy with anti-corrosion coating. Main circuit board is multi-layer flame-retardant glass fiber epoxy PCB. Gold-plated copper alloy slot connectors. Power and signal traces use impedance-controlled copper lines. Terminal blocks are flame-retardant PA plastic with nickel-plated copper terminals.
Structural Features Rack-mounted integral backplane assembly. Multiple parallel module slots arranged in rows. Each slot equipped with gold-plated female connector for plug-in modules. Rear side integrated power input terminals and signal output terminals. Metal reinforcing frame supports the PCB board and maintains flatness.
Working Principle Rack power supply module inputs DC power to backplane power terminals. Internal power traces distribute DC power to every module slot. When monitoring modules are inserted into slots, modules obtain power and connect with internal bus traces. Measurement data and alarm signals of each module transmit through backplane bus traces. Relay alarm signals pass through dedicated routing traces and output to rack external terminals.
Installation Requirements Install backplane assembly into standard machinery protection cabinet and fasten fixing screws. Connect rack power cables to backplane power terminals. Ensure protective earth wire connects to cabinet ground bus firmly. Keep module slots free of dust and metal debris before inserting modules.
Precautions for Use Cut off rack power before backplane maintenance or module insertion and removal. Do not touch gold-plated slot connectors directly by hand. Keep backplane surface clean; remove dust regularly with dry compressed air. Do not insert damaged modules into slots. Inspect connector contact condition periodically.
