*WANDFLUH* *Hydraulics+ Electronics*					*Amplifier / controller electronics*

Integrated electronics amplifier and controller for proportional hydraulic valves • with analog interface • with CANopen interface • 24 VDC or 12 VDC			MART

DESCRIPTION		FUNCTION			APPLICATION

Wandfluh has extended its range with a technology module and as of new is able to offer proportional valves with integrated, intelligent electronics. Housing for electronics with protection class IP67 for harsh environment. Un-der the expression „Digital Smart Valve", in the smallest possible space a digital amplifier electronics system is concealed, which at the present moment represents the most compact design available on the market. As a result of the compact construction, Wandfluh is in the position to also offer miniature valves of the standard size 4 in an optimum, slender design. In addition to this, Wandfluh as the only manufacturer is in a position to offer proportional screw-in cartridges M22 und M33 with inte-grated electronics.		The control connection is provided by an analog interface or a CAN interface. Parameter setting and diagnosis with the free-of-charge software „PASO" or via CAN interface. Data are stored in a non volatile memory. Even af-ter an electric power failure settings can eas-ily be reproduced and transmitted. These valves are available with an integrated axis controller as an option. As feedback signal source sensors with voltage or current output signal can be directly connected. The availa-ble controller structure has been optimised for applications with hyraulic axis.			The „DSV" electronics are used by Wandfluh exclusively for proportional hydraulic valves. They are factory set and adjusted in order to guarantee a high valve-to-valve reproducibil-ity. The hydraulic valves are implemented in systems calling for good valve-to-valve repro-ducibility, easy installation, comfortable operation and high precision. The integrated axis controller reliefs the machine control system and operates the axis (position, angle, pressure, etc.) in a closed control loop. The applications lay in the industrial- as well as in the mobile hydraulic field for the smooth control of actuators.
