Description
Emerson A6312‑08
Technical Specifications: Redundant dual‑channel 24 VDC power input Input voltage working range: 20‑28 VDC Module mechanical width: 8 TE Euro‑card standard dimension Higher rated output load compared with A6312 6‑TE version Galvanic isolation between input power and rack internal power bus Power‑fault alarm output: dry‑contact relay signal Operating temperature: 0 ℃‑60 ℃ Storage temperature: ‑40 ℃‑85 ℃ Relative humidity: 5%‑95% non‑condensing
Functional Features: Dual‑redundant power‑input diode‑or backup, seamless switch when single‑path power source fails. Higher power‑output capacity adapts to full‑load rack with large‑quantity monitor modules. Real‑time monitoring for internal output‑bus voltage. Dry‑contact relay outputs remote power‑supply‑failure‑alarm signal. Front‑panel LED indicators display working status of two input‑power‑supply paths. Built‑in over‑current short‑circuit protection circuit. Rear‑side DIN41612 standard connector connects rack power‑distribution backplane.
Application Scenarios: High‑load AMS6500 machinery‑protection rack power‑supply unit for large‑scale steam‑turbine, gas‑turbine and centrifugal‑compressor monitoring system in power‑generation and petrochemical industry.
Performance Parameters: Support full‑slot AMS6500 rack maximum load power consumption Vibration resistance: 10 Hz‑150 Hz, 0.5 g Shock resistance: 10 g peak acceleration, 11 ms duration MTBF value: 226000 hours
Material Composition: Module front‑panel: UL94‑V0 flame‑retardant reinforced plastic. Main circuit substrate: thickened FR‑4 glass‑fiber epoxy printed board. Rear‑side connector: DIN41612 gold‑plated multi‑pin connector. High‑power semiconductor components match metal heat‑dissipation fins. Fault‑alarm relay adopts industrial‑grade sealed‑package relay.
Structural Features: 8 TE wide Euro‑card plug‑in module, installed at dedicated power‑supply slot on left side of AMS6500 rack. Front‑panel reserves dual‑path power‑input wiring terminals and group of LED status indicator lights. Rear‑side large‑size DIN‑standard connector docks rack internal power‑distribution backplane. Larger‑area internal heat‑dissipation fins adapt to higher‑power‑output heat‑dissipation requirement.
Working Principle: Two independent external 24 VDC power sources connect to dual‑input terminals of module. Internal diode‑auctioneering circuit implements redundant power‑source seamless switching. Higher‑capacity power‑conversion circuit provides stable 24 VDC power‑bus for every module slot inside rack. Voltage‑monitoring circuit continuously samples output‑bus voltage value. When input‑power loss or output‑voltage abnormality occurs, fault‑alarm relay acts and outputs remote dry‑contact alarm signal.
Installation Requirements: Insert A6312‑08 module into dedicated 8‑TE power‑supply slot on left side of AMS6500 rack. Guarantee full engagement between rear‑side connector and rack backplane. Two‑way redundant power must come from two completely independent external power‑supply sources. Tighten power‑input terminal‑screw torque to 0.6‑0.8 N·m. Cut off all external input power‑supply before wiring work.
Precautions for Use: Forbid to connect single‑power‑source parallel output as two‑way redundant input. Wear anti‑static wrist‑band when maintaining module internal circuit. Keep internal heat‑dissipation fin area free of dust accumulation. Do not install in environment with conductive dust and corrosive vapor. Stop module usage in case of shell over‑heating or burn‑trace appearance.
