S070

Product Overview

The S070 module is a compact slave electronics module design to add direct drive capability for common-rail diesel engine fuel injectors to the OpenECU M2xx family of intelligent electronics control modules.

Each module can be configured to provide up to 6 fully protected drive channels that are suitable for solenoid injectors.

There is an option to include an internal diagnostic microprocessor module and CAN interface that deliver diagnostic information to other vehicle systems and control configuration options via software commands.

Injector Output Features
  • Capable of driving up to 6 separate solenoid injectors, one injector at a time.
  • Capable of driving injectors at battery voltage with closed loop peak/hold current control
  • Capable of driving injectors at boosted supply voltage at the start of the injection, and switching to battery voltage for the rest of the injection.
  • Capable of firing multiple injections per TDC.
  • Individual high side source pins are connected internally to a common high side switch
  • Each individual low side pin is controlled with a dedicated low side driver
  • Closed loop PWM current regulation at two different levels (peak and hold)
  • Protection against reverse supply connection
  • Inputs / outputs protected against short to supply or ground
  • All outputs have Inductive load and over-current protection
  • All pins are ESD protected to ±8kV
