The AN402 servo amplifier module is intended for the control of single magnet proportional valves
The control algorithm, ramps and similar command variables are derived exclusively from an external computer (PLC)
Snap-on housing enables mounting on normal carrier rails in control cabinets
Electrical connections via a terminal strip and a flat connector (enable input)
Duplex output stage with high-dynamic response and rapid deexcitation
Rapid switch-off of the magnet coil (approx. 4...6 ms)
Multi-turn resistances allow the adjustment of volumetric flow amplification, pressure amplification and Imin jump
Integrated ramp generator that allows adjustment of the ramp times (ramp up, ramp down) by means of two multi-turn resistances
The ramp can be switched off externally by an input (ramp off)
