PD3 with Bluetooth interface
For the simple and inexpensive control of a proportional valve, Wandfluh has developed the digital amplifier electronics PD3. The device can be mounted directly on a solenoid coil (see picture) or connected to a standard solenoid coil with a cable.
The device has a standardised IO-Link interface. It consists of a digital communication, via which the parameters, diagnostic data and the command are transmitted to the valve control. With the IO-Link interface, the PD3 electronics is prepared for IoT and Industry 4.0 functionalities.
In addition, the control can also be made as an analog voltage or current signal, or via a digital frequency or PWM signal. The PD3 electronics is IP67-protected and has LEDs which indicate the status of the functional elements of the control.
