Woodward 9906-730
Product Name: EGS-02 Gas Engine Full-Authority Digital Controller
Product Introduction: Maritime top-tier version, simultaneously integrating three software authorizations: maritime certification + low-heating-value gas adaptation + lean-burn low-emission. Triple-proof circuit board coating. The most functionally complete model in this maritime series.
Detailed content
Technical Specifications: Hardware electrical parameters same as 9906-727; classification society maritime certification; circuit board triple-proof salt-fog moisture-proof coating; all software function authorizations enabled.
Functional Features:
-
Integrates all functions of 9906-728 and 9906-729
-
Low-heating-value gas self-adaptation
-
Lean-burn low-emission control
-
Complete maritime event logs
-
All I/O channels fully enabled
-
Complete Modbus communication
Application Scenarios: Marine vessels and offshore platforms using landfill gas / biogas low-heating-value gas sources while needing to meet maritime emission regulations for gas reciprocating units.
Material Composition: Sheet metal enclosure, circuit board triple-proof coating, corrosion-resistant gold-plated terminals, flame-retardant insulation internal components.
Structural Features: Panel-mount control cabinet installation, rear wiring terminals, hardware appearance same as other models in the series, distinguished by nameplate.
Working Principle: Marine anti-interference hardware, simultaneously completing low-heating-value gas source compensation, lean-burn closed-loop emission control, speed regulation, and unit fault protection, adapting to complex marine power and electromagnetic environment.
Installation Requirements: Marine control cabinet panel-mount, shock-absorbing accessories; all signals use marine shielded cables; standardized grounding, ventilation and heat dissipation, away from strong electromagnetic equipment.
Usage Precautions: After major gas source component changes, recalibrate and self-learn; must be placed inside control cabinet, cannot directly contact salt-fog; static electricity protection, prohibit hot-plugging terminals under power.
