The AN422 servo amplifier module is intended for the control of proportional valves with two magnets
Snap-on housing enables the AN422 module to be mounted on normal carrier rails in control cabinets
Electrical connections are via a terminal strip and a flat connector (enable input)
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
The module has an integrated quadrant-sensitive 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 via an input (ramp off)
