These are the specs
VX Ignition Specifications:
Ignition Drive High 20mA @ 5V
Ignition Drive Low 2A over current protected
Open Collector (not fly-wheeled) in auxiliary output mode
I believe it is just a signal at 5v 20ma, the device is a vipec v88, in the manual it connects to an igniter, I can't see it actually driving the 1000v signal. But I can't say for sure and not sure how to confirm.
Thanks I was just guessing with R2. V1 is the ECU, provides a pulse signal or square wave output of varying frequency dependant on RPM of the engine. Also thanks for clearing up the 0v current draw.
Thanks for the reply, i will look into your method.
For now going with 5v, i think its much easier, this is a simple design i came up with using TTL. My only worry is, im not sure how much current is drawn from the voltage pulse generator when the AND gate output is 0. Looking at the data sheet...
Yes, it is the signal from the ECU to the coil pack to be more specific, this is only 12v, I am using another LED and resistor to model this part of the circuit. I just need to be able to divert this signal from the ECU to another load when the Arduino is HIGH.
Hi all
Im looking for a way to switch a 12v signal between 2 loads. One load will be a spark plug (Load 1), the other an LED + Resistor (Load 2). I need to be able to switch between the 2 loads by signalling through the Arduino 3.3v pin (HIGH or LOW). This is relatively simple, however the bit...
