Position control tab of a hydraulic actuator with analog feedback The EWM-S-AA digital card is a position controller designed for the precise management of the race of a hydraulic actuator equipped with analog position sensor (0–10V or 4–20ma), perfect for piloting proportional valves and serve-proportional valves with integrated electronics in closed ring systems. The module allows reliable and reactive control, with configurable exit (± 10v) or current (4-20ma), selectable via software. Thanks to the integrated profile generator (SDD/NC) and the advanced compensation of the dead band, it guarantees precise, stable and repeatable movements. The device includes an entrance for the control of external speed, useful for applications where you want dynamic management of the movement profile. All operating parameters can be easily set through the EWM Smartmanager EWM software, downloadable from this same page. The connection takes place via the USB port integrated on the front of the front, which allows a quick configuration, diagnostic in real time and signal monitoring. The EWM-S-AA is ideal for industrial applications where it is required: precise control of the position on hydraulic service service direct interface with proportional valves with integrated electronics The start-up manual can be downloaded from this page or by the area reserved only by customers in possession of credentials.
