We have designed two specific controls for Welact 400 whose name is
SCARES W400-12 / 24 Actuators Control System with Electronic Feedback Simple to W400.S
CAREP W100-12 / 24 Actuators Control System with Electronic Feedback Accurate for W400.
SCARESP W300-12 / 24 Actuators Control System with Electronic Feedback Simple Knob W400.
The difference between the first two lies in positioning accuracy, they let through a display visualize the position (in millimeters) of the piston.
