PEES COMPONENTS AN423 User manual
The AN423 servo amplifier module is intended for the control of single magnet
proportional valves.
The snap-on housing enables the amplifier module to be mounted on normal carrier
rails in control cabinets. The electrical connections are via a terminal strip and 3 flat
connectors (enable input, reference voltage +10V and GND).
Four multi-turn resistors allow the adjustment of volumetric flow amplification (Imax.),
Imin jump (Imin.) and the acceleration and deceleration ramp times (ramp up and ramp
down) to be adjusted externally.
