Woodward 8404-1001 Multi-Cylinder Ignition Controller

Product Brief Introduction Multi-cylinder digital ignition controller for industrial gas engines, delivering cylinder-specific timing and sequential spark control for multi-cylinder engines.
Tag:

Technical Specifications Supply: 18–32 V DC; speed input: 1 channel magnetic pickup; ignition outputs: up to 8 cylinder channels; timing range: 0–60° BTDC; operating temperature: -40 °C to +85 °C; enclosure: IP54; communication: RS-485 Modbus RTU.

Functional Features Sequential cylinder ignition; per-cylinder timing trim; programmable timing map; dwell control; misfire detection per cylinder; Modbus monitoring and configuration.

Application Scenarios Multi-cylinder industrial gas engines, V6/V8/V12 generator sets, large stationary gas engines, cogeneration plant ignition control.

Performance Parameters Timing accuracy: ±0.5° crank angle; cylinder-to-cylinder timing skew: < 0.3°; misfire detection: per-cylinder; update rate: 10 ms.

Material Composition Die-cast aluminum enclosure; multi-channel power output stage; microcontroller core; sealed input/output connector.

Structural Characteristics Panel or engine mount; front status LEDs; multi-pin sealed connector; mounting flanges.

Working Principle Uses engine speed and position signals to determine crank angle, fires each cylinder sequentially per the programmed timing map, and controls dwell to maintain consistent spark energy per cylinder.

Installation Requirements Mount in protected location on engine; connect speed pickup, coil harness and power; program cylinder timing and firing order; verify timing per cylinder.
