The MIC100 has the following electrical characteristics.
Feature |
Value |
---|---|
Power consumption |
Max. 40 W at 24 V |
Power supply |
Nominal voltage: 24 V DC |
Required current |
Max. current 2.0 A. An estimation of the power requirements can be found after this table. |
Number of outputs |
4, 6 or 8 outputs |
Firing angle |
The size of the firing angle depends on the max. overspeed. The smallest ignition angle can be calculated using the following formula: |
Ignition frequency |
With full energy output (all 8 ignition outputs with 130 mJ), an ignition frequency of 120 Hz as continuous load is possible. With less ignition energy or in case of a brief overload, 133 Hz is possible. The maximum output load of 18 W must not be exceeded. 2-stroke engine: 4-stroke engine: |
Estimation of Current Requirements
These current values are based on a nominal speed of 1800 rpm and 130 mJ energy.

Electrical Data for Inputs and Outputs
The inputs and outputs of the ignition controller have the following electrical data:
Inputs and outputs |
Values |
---|---|
Analog current input |
Current range: 0 mA to 20 mA (adjustable in MICT) |
Binary input (Start/Stop) |
Wiring Input current: max. 20 mA |
Go/NoGo output |
Implementation as bipolar power transistor Maximum switching voltage: 32 V DC Peak/steady current: max. 100 mA DC Output power: max. 2.5 W Internal resistance: 58 Ω to 60 Ω Activation delay: 0.5 ms / max. 100 mA load Deactivation delay: 0.2 ms / max. 100 mA load If a short is found at the output, a safety circuit, which makes the output highly resistive, is found at the output, so that the current sets itself at 50 mA to 60 mA. |
LED |
Three LEDs are used as status indicators. |
ASO output |
TTL level (5 V) |
Pickup input |
Impedance: 10 kΩ Power supply 8 V or 15 V (configurable in MICT) Max. frequency for the pickup: 15 kHz The formula for determining the frequency of the pickups can be found in the note following this table. For a pickup output impedance of 120 Ω to 10 kΩ, the pickups connected to the MIC100 may not have a higher voltage than ±40 V and the connected power may not exceed 1 W. |
Ignition coil outputs |
Output voltage: max. 250 V Output energy in normal operation mode: 130 mJ |
Frequency of the pickups The frequency of the pickup is calculated as per the following formula. |
