AN418
Servo Amplifier
The AN418 servo amplifier module is intended for the control of proportional valves with two magnets. The snap-on housing enables the AN418 module to be mounted on normal carrier rails in control cabinets. The electrical connections are via a terminal strip and a flat connector (enable input).
The output stage is a duplex output stage with high-dynamic response and rapid deexcitation. These design features ensure rapid switch-off of the magnet coil (approx. 4...6 ms).
Four multi-turn resistors allow the adjustment of volumetric flow amplification (max. A, max. B), and Imin jump (min. A, min. B) to be made separately for each magnet.
