Omschrijving:
  • 4 digital outputs
  • Control of PWM output signals based exactly on NetTime
  • 4x oversampling output functions
  • Integrated output protection
  • 24 VDC and GND for actuator power supply

The module has digital outputs for connecting electromechanical loads (e.g. valves and relays) and additional functions such as edge generation.

With a resolution down to 125 ns, the module makes it possible to set switching operations at exactly specified moments.

The following operating modes can optionally be supplemented with PWM functionality:

  • Direct I/O
  • Oversampled I/O
  • Edge generator
  • Edge generator in toggle operation for output patterns such as digital cam switches (e.g. digital cam switch of function block "ASMcDcsTimedDigitalCamSwitch")

Additional functions:

  • PWM modulation of outputs for setting the overexcitation and holding current.
  • Configuration of each channel by specifying PWM period duration
  • Control value for overexcitation current, holding current and overexcitation time
  • Possibility of disabling high-speed cutoff
