Function
The I/H converter is an electro-hydraulic, remote controllable current-to-pressure converter.
With a setpoint of w = 0/4 mA to 20 mA, the requested output pressure PA can be set
quickly and hysteresis-free. For instance, a pilot piston or a hydraulic cylinder may be
positioned against a restoring spring.
For the operation of the I/H converter, electric and hydraulic auxiliary energy is required. All
electric components necessary for the I/H converter operation are integrated in the I/H
converter and protected against environmental influences. The controllers with connections
for setpoint limitation and magnetic force control are installed in the Voith control magnet
(VRM). With potentiometers X0 and X1 which are accessible from outside, the output
pressure PA can be allocated to setpoint w.
Function of manual operation knob
The control magnet of the I/H converter is provided with a manual operation knob. Same
can be used instead of the magnetic force F
Mag
to define a spring force, adjustable via the
manual operation knob, which controls the piston via the magnet armature and the tappet.
The hydraulic force F
Hyd
being proportional to the output P
A
acts against this spring force.
Thus adjustment of the output pressure is possible without electric connection.
