Outputs
Proportional outputs
The current /PWM outputs control proportional valves and devices. For the current
range and loads, see Appendix A, on page 46.
Frequency
To obtain the best performance from proportional valves the IQAN-MC3 produces a
current mode (closed loop) output signal. The units have an adjustable frequency which
can be changed using IQAN software.
The table below shows the MC3 frequency possibilities. Any frequency may be entered
in your application and is translated according to this table. The bold values are the
actual frequencies in Hz output by the MC3 for proportional valve control.
