Potentiometer with OFF-position to control fan speed or the position of dampers in a ventilation system. The supply voltage is 24 Volt DC. The continuous variable output signal can be set via the rotary knob. In OFF-position (ultimate counter clockwise position), the control signal is 0. By default, the analogue control signal goes from low to high value by turning the knob clockwise. This functionality can be inversed via the Modbus holding registers. The minimum and maximum output values can be adjusted via the Modbus holding registers. A complete overview of all adjustable settings is available in the Modbus register map of this product. The splash-proof enclosure allows inset mounting (IP44) or surface mounting (IP54).
