Notes from Hannover: Nine new ideas worth a look

Simple proportional control

For the simple and inexpensive control of a proportional valve, Wandfluh has developed the digital amplifier electronics PD3 unit. The device can mount directly on a solenoid or connect to a standard coil with a cable. It has an IO-Link interface and provides digital communication to transmit operating parameters, diagnostic data and commands to the valve control. With the IO-Link interface, the PD3 is suited for IoT and Industry 4.0 functions.
