A direct fire 4 channel Capacitor Discharge Ignition System available in single or multiple discharge models.

Designed for direct fire of engines up to 8 cylinders and 2 rotor rotary engines. It contains a pair of 2 output ignitions (two dump capacitors) allowing simultaneous ignition on 2 outputs for twin plug or split ignition application.

The trigger inputs are highly interference tolerant minimizing any chance of cross triggering of ignition channels. High efficiency circuitry ensures cool running and safe operation in hot environments.

This unit is capable of full ignition output power up to 18000 RPM and will function to 22000 RPM even in 8 cylinder applications.

Additional features:
Output power is selectable at 2 levels.
12 volt square wave Tacho O/P.
Low current ON/OFF control input.
