Description

the EWM-PQ-AA is a p/Q axis card for controlling a high-response valve with zero overlap spool and hydraulic actuator equipped with analogue pressure sensors. The controller automatically switches from flow control to pressure control to keep the pressure within the set limits. pressure is controlled in closed loop only with positive flow value. The output value to control the valve in voltage or current must be configured via software. The EWMPC/20 software can be downloaded from this page. Connection via USB port on the front panel. The start-up manual is available for our customers after obtaining credentials to access the reserved area.

Key Features

• Multifunction card for both pressure and flow regulation • High-resolution feedback for precise control • Compatible with various sensors
