Description
4 digital outputsControl of PWM output signals based exactly on NetTime4x oversampling output functionsIntegrated output protection24 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/OOversampled I/OEdge generatorEdge 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 durationControl value for overexcitation current, holding current and overexcitation timePossibility of disabling high-speed cutoff
