What’s in the box

  • 1x MonoDAQ-E-DO4
  • 1x Passive PoE power injector
  • 1x USB-to-12 V power supply



Isolated digital outputs with high current capability can drive motors, pumps or valves as well as trigger pure digital signals. Three power supply voltages (5V, 12V and device voltage supply level) available on the front connector. EtherCAT interface, signal and power over the same cable.

    The ease of use of DEWESoft software to configure on-device PWM is very important for our work. We can easily drive motors in our test with the DO4 device.
