AUTRONIC 500R CDI Configuration overview

Feature	Configuration (for HF suffix serial numbers)
4 Output channels	Direct fire non-waste spark on up to 4 cylinder engines Direct fire on 2 rotor rotary engines Waste spark fire on up to 8 cylinder engines (4-stroke only)
2 Internal ignition units for simultaneous or split triggering of two output channels	Twin spark plug per cylinder engines or rotary engines Split timing between plugs in same cylinder or rotor
Two output power levels selectable by either switch or ECU control	Low power 1st spark – 100 mJ High power 1st spark – 125 mJ
Second spark at low RPM	Second spark capability (RPM/Simultaneous/Split dependent) Can be inhibited by trigger signal pulse time if required
Triggering by –ve (negative) signal edge	Same triggering as most conventional transistor type ignition modules
Tacho output	12v square wave for electronic tachometers
EMC compatibility (C-Tick compliant)	Shielded / twisted cables NOT required for installation
