Potentiometer | OFF position | Modbus RTU | 24 VDC supply


Product description

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).

Additional specifications and description

 
Typical applications
The analogue output of the potentiometer is typically used as a control signal. Typically, a potentiometer is used to remotely adjust EC fan speed or to send the requested motor speed to a frequency inverter or AC fan speed controller. E.g. the potentiometer can be installed in the living room while the fan speed controller is located in a technical room or electrical cabinet.  
 
Output type
Different output types can be selected: 0-10 Volt / 0-20 mA / 0-100 % PWM. The output type can be adjusted in Modbus Holding register 11.
Also the minimum and maximum output values can be adjusted via the Modbus holding registers.  
 
Output overwrite
When the output overwrite function is enabled, the output value can be set via Modbus RTU communication. That makes it possible to overrule the rotary knob and to remotely control the analogue output value of the potentiometer via Modbus RTU communication.  
 
Output regulation type
By default, the analogue output goes from low to high (e.g. 0 to 10 Volt). It is possible to reverse the operation. In that case, the output value goes from high to low (e.g. 10 to 0 Volt). The output regulation type can be selected in Modbus Holding register 17.  
 
OFF position
This potentiometer has an OFF position.
In OFF position (counterclockwise position), the analogue output value is 0 %.
