Circuit of electronic ignition OEZ4 (OEZ43)

Electronic ignition OEZ4 (OEZ43) is determined for small four (three) cylinder motors without necessity to change set pre – ignition during motor operation (thus is fixed by DIP-switch) Detailed description of ignition OEZ43 can be found here.
Variant OEZ4 is determined only for four cylinder Elektronické zapalování OEZ4 motors and has selectable re - phasing of outputs of 180°. As for variant OEZ43 it is possible to select number of cylinders of motor (4,3). We offer also ignition variant OEZ43VW determined for coils Bremi with integrated switch).

Basic features:

• Supplying voltage 12V, 2.5A
• Number of switching coil outputs 4
• Range of pre –ignition adjustment 90° (4-cylinders), 60° (3-cylinders)
• adjustment step of required pre – ignition by DIP - switch (Range / 128) is 0.7° (4- cylinders), 0.47° (3- cylinders)
• Number of input signals 2 (CLK, RES)
• Output signal with information about motor rotation (able to connect for example into rotation input of control system)
• Selection of type of input sensors (Hall sensor unit, Induction sensor)
