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 sup­plied 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.
