Number of
Channels
Electronic module for the control of proportional
pressure or flow valves. The pressure-/ flow values
are given by externally supplied command signals
and internal ramp potentiometers.
Features
• Processing and amplification of externally sup-
plied positive commands into output signals for
the control solenoid.
• Up to 6 independent channels for the control of
up to 6 valves.
• Each channel is equipped with a slide switch for
selection of pressure or flow valve operation.
• Ramp function
• Pulsed low loss amplifier power stages with
supporting constant current control for constant,
temperature independent solenoid forces.
• Dither generator with applied frequency to
improve static characteristics.
