Product description

Introducing the SPV-8-010-PM, a revolutionary potentiometer that redefines manual control for ventilation systems. With Modbus RTU communication, this device offers seamless integration into various applications, providing users with unparalleled flexibility.

Designed for global compatibility, the SPV-8-010-PM operates on a supply voltage of 85-264 VAC at 50-60 Hz. This broad range ensures adaptability to almost any mains power worldwide, making it a reliable choice for diverse environments.

This potentiometer takes control to the next level by managing EC fans, AC fan speed controllers, or damper actuators. Choose from a range of output types, including 0-10 V, 0-20 mA, or 0-100% PWM while a simple twist counter-clockwise to its OFF-position disables the control signal. Its versatility extends to settings such as normal or inversed operation, minimum and maximum settings, and output overwrite. Access all these features effortlessly through the Modbus registers, offering a customizable experience tailored to your specific needs.

Thanks to Modbus RTU, the SPV-8-010-PM can be accessed remotely via a Building Management System (BMS) or through the SenteraWeb cloud. This connectivity opens up a world of possibilities, from standalone usage to becoming an integral part of a comprehensive ventilation management system.

The SPV-8-010-PM doesn't just stop at performance—it's built to withstand the elements. Housed in a splash-proof enclosure, it offers the flexibility of both inset mounting (IP44) and surface mounting (IP54). This ensures durability and reliability, even in challenging environments.

Additional specifications and description

 
Generate a 0-10 Volt control signal manually
SPV series are potentiometer that generate an analogue control signal (e.g. 0-10 Volt signal). This signal can be adjusted manually via the knob of the potentiometer. Turning the potentiometer knob clockwise will increase the analogue signal from low to high (default setting). The analogue control signal is typically used to control EC fans or damper actuators. It can also remotely control AC fan speed controllers (EVS or MVS series) or frequency inverters (FI-E series).
  
New improved series
SPV-8-010-PM is the successor of the good old MTV-1-010-PM series and has almost the same functionality, but is better. The old technology using jumpers is replaced by Modbus RTU communication, the control algorithm is enhanced, the wiring is done using a push-in CAGE CLAMP® connection and last but not least the looks are improved in order to suit modern interiors. You can still use the SPV as a manual potentiometer, but to make use of the whole set of its features, we advise on using Modbus RTU communication. 

Modbus RTU communication
This is not just a simple potentiometer. This is a state-of-the-art digital potentiometer. It can work stand-alone or it can be integrated in a Modbus-RTU network. This offers the possibility to set the 0-10 Volt signal manually via the potentiometer or to overrule the manual control via Modbus RTU communication. Via Modbus RTU communication, the potentiometer output value can be overwritten. The potentiometer position, the output value and all other parameters can be read via Modbus RTU communication. The complete parameter list is available in the Modbus register map on the product page.
  
Remote control via SenteraWeb cloud
Via an optional internet gateway, this potentiometer can be connected to SenteraWeb - the online HVAC portal. This makes it possible to remotely read out the output value or even to overwrite this output value. SenteraWeb features a day-week timer. This makes it possible to overwrite the potentiometer output during certain moments in the day or week. There is no need to install apps or software to use SenteraWeb. SenteraWeb is accessible via a standard web browser like Google Chrome or MS Edge.
  
Adjustable minimum and maximum level Diagram with black and green lines
Some EC motors or valve drives cannot handle control signals that are too small. Sometimes a fan is overdimensioned or too powerful. No worries, the upper and lower limits of this potentiometer's output can be adjusted via Modbus RTU. E.g. by default, the output signal is 0-10 V. This can be adjusted to 4-9 V or another customised range.
  
Reversible output signal
By default, this potentiometers output goes from low to high. It is possible to inverse the output of this potentiometer so that it goes from high to low. E.g. by default, the output signal is 0-10 V. This can be adjusted towards 10-0 V.
  
230 VAC power supply
This potentiometer works directly on 230 VAC mains voltage. No separate power supply is required! Simply connect the potentiometer to the power distribution network and control your ventilation. 
  
Different output types
The output type of this potentiometer can be selected via Modbus RTU communication. There are 3 possibilities: 0—10 V, 0—20 mA or 0—100 % PWM. The easiest way to change the output type is via 3SModbus software or via SenteraWeb.

Bardzo precyzyjny potencjometr do ręcznego sterowania wentylatorami. Możliwe jest również sterowanie wyjściem potencjometru poprzez Modbus, co sprawia, że nadaje się do integracji z BMS. Fajna nowoczesna obudowa

Our representative advised us to start buying this instead of the old MTV. The price is almost the same, but it really controls better and looks more modern.

Very precise potentiometer for manual control of electronically commutated fans. It is also possible to control the output of potentiometer via Modbus, which makes it suitable to be integrated in BMS or to be part of installation in Senteraweb.
