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.
