Trigger input

EC36/28: +5V output for HALL sensors (max 50mA recommended)


Ignition outputs (1,3,4,2 firing order)

4A biztosítékon át a gyújtótrafó másik vége tápfeszre (+12V vagy +24V DC) van kötve


IAC PWM output

  • TPS in EC36/1 0,75-4,25VDC CORRECT??
  • 0-90% (or 10-90% )
  • EC36/pin11 (ign4) 0/5V (max: 1.1mA)
  • alternatively: EC18/pin4 (Stepper A) 0/12V

Woodwars spec:

PWM Command Input (+PWM at pin 11, PWM ground at pin 3)—This actuator

can be configured to handle a PWM signal from a high-side or low-side opencollector

or open-drain source, as well as from a push-pull (customer pull-up)

source. The necessary pull-up and pull-down voltages to accommodate the

open-collector sources are handled within the L-Series actuator. Nominally, the

frequency of PWM is 1 kHz, but it will handle the full range of 300 to 1500 Hz.

See Figure 3-5 below, which describes the possible input types and

configurations for the PWM input.
