PSW Basic

The PSW Basic Pump signal converter is used for connecting speed-controlled high-efficiency pumps with a PWM or 0-10 V control input to a controller without a corresponding output. Thus, when replacing the pump, speed control can be enabled without replacing the controller. The PSW Basic is small, easy to install and simple to connect. It covers a large part of the most common signal combinations – it converts the signal of a speed-controlling semiconductor relay into either a PWM or a 0-10 V signal, both of those inverted if necessary.
