Potentiometer | dry contact | Modbus RTU | 24 VDC
Product description
The SDP-M010-DC is an advanced potentiometer for precise ventilation control with Modbus RTU integration, allowing connection to a BMS or the SenteraWeb cloud.
It features a rotary knob for continuous manual control and a dry contact for remote on/off switching, with no mechanical OFF-position to prevent accidental shutdowns.
Essential parameters can be adjusted remotely via Modbus. The device is durable, with a splash-proof enclosure and options for IP44 inset or IP54 surface mounting.
Additional specifications and description
What are the typical applications of this potentiometer?
The analogue output of the potentiometer is typically used as a control signal. In general, 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. For instance, the potentiometer can be installed in the sitting room while the fan speed controller is located in a technical room or electrical cabinet. 
What additional features does it have?
This potentiometer features Modbus RTU communication, which is a standard communication protocol for communication between electronic devices. It is easy to deploy and maintain and therefore is often used to connect a plant/system supervisory computer with a remote terminal unit (RTU).
Sentera has developed its free downloadable 3SM Software whose intuitive interface facilitates the process of configuration, monitoring or updating of products featuring Modbus RTU.
What output types are available?
The SDP series offers different output types: 0-10 Volts, 0-20 mA and 0-100 % PWM. The output type can be adjusted via Modbus Holding register 11.
Also, the minimum and maximum output values can be adjusted via the relevant Modbus holding registers.

Also, the minimum and maximum output values can be adjusted via the relevant Modbus holding registers.
When the output overwrite function is enabled, the output value can be set via Modbus RTU communication. This makes it possible to overrule the rotary knob and to remotely control the analogue output value of the potentiometer via Modbus RTU communication.
By default, the analogue output goes from low to high (i.e. 0 to 10 Volt). It is possible to reverse the operation. In this case, the output value goes from high to low (i.e. 10 to 0 Volt). The output regulation type can be selected via Modbus Holding register 17.
The dry contact output can be used to control an external device (e.g. start - stop command for fan speed controller). When the rotary knob is in OFF position (counterclockwise), the contact output is open. When the rotary knob is turned clockwise, the contact closes.
What does the OFF position do?
This potentiometer has an OFF position. In OFF position, the dry contact output is open and the analogue output value is at its minimum value.
What makes installation of the SDP series easy?
The SDP series offers an exceptional simplicity of installation, featuring a modular screwless terminal block with a 5 mm pitch. This not only reduces installation times but also enhances user experience by eliminating the need for twisting and turning screws. The screwless clamping technology ensures a secure connection without the need for constant checks or retightening of loosened wires due to disturbances, temperature cycling or strand breaks.

What makes the enclosure reliable?
The SDP series of potentiometers is fit for both surface and flush mounting, meaning you can install it on or in any kind of wall – a solid wall, drywall or even a wood panel. The mounting holes fit perfectly the standard European wall boxes used for flush mounting. The protection class is IP44 for flush and IP54 for surface mounting. Furthermore, it looks really nice and is a good match for any interior style. Cleaning it is very easy using only a damp cloth.
So, there is no need to opt for two different versions as the SDP series combines both of them! All you need is a couple of tools and a little bit of general knowledge and handiness.
