Overview
Speed control of high-efficiency pumps for controllers
without integrated PWM outputs.
Easy to install.
Convertible from PWM to 0-10-V-Signal.
With 7-segment LED display.
The VBus /PWM interface adapter is used for the speed
®
control of a pump via a PWM or 0-10 V signal. Via the VBus
the adapter receives information from the controller about
speed. The speed is converted into a PWM or direct volt-
age signal and put out to the corresponding terminals.
A signal corresponding to the speed is only available if the
corresponding relay is designed for pump speed control.
Otherwise, a signal – depending on the position of the relay
– for the on or off state is transmitted.
