Ignition control IC920 - IC922

The IC-920/-922 is a versatile ignition control that is user configurable for a variety of engine installations. A single IC-920/-922 ignition control can be configured to fit numerous engine makes, models, and sizes and used in gas compression, electric power generation, and other industrial applications.

The IC-920 and IC-922 fires up till 20 ignition coils with and option of 24 coils.

Key features:
  • Ideal combination with any Woodward Full-Authority control (air fuel ratio control)
  • Bi-directional communication via CANbus: CAN J1939, CANopen, or custom CAN
  • Timing Control:
    • Manual timing potentiometers
    • 4–20 mA or 0–5 V input
    • Timing vs. Speed curve
    • Controlled via CANbus network
  • Misfire detection
  • Overspeed protection
  • Easy configerable with free tool
  • Standard 20 coils, optionall for 24 coils

Woodward's IC-920 ignition systems provide the essential high-energy spark needed for lean-burn engines that operate at higher mean effective pressures and with larger cylinder bore sizes.

The IC-920is a modern high-energy capacitance discharge ignition system. The system includes all the required software needed to configure any type of industrial engine. There is never a requirement for factory reprogramming of the IC-920 software. All user programming/configuration is completed by free IC-900 Series Service Tool software residing on a PC (personal computer).

The IC-920 uses information provided by the timing sensors to precisely determine the correct crank angle for firing each output. Engine ignition timing is controlled automatically or manually by various inputs, such as a manual timing potentiometer, 4–20 mA or 0–5 V signal, speed curve, or through a CAN serial link.

During operation, the IC-920 continuously monitors the status of the system by verifying proper information from all timing sensors and proper operation of the primary ignition circuit. Depending on the severity of a detected fault, the unit will either shut down or warn the operator. A message is transmitted in either case to a PC or optional display via a serial link.
