Additional specifications and description
is a 0-10 V
series can be used as a simple potentiometer. Via the rotary knob, an output
value can be set. This output value can 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). The default output is
0-10 V. This can be adjusted if necessary. The output type of this potentiometer can
be selected via Modbus RTU: 0—10 V, 0—20 mA or 0—100 % PWM.
This potentiometer works directly on 230
VAC mains voltage. No separate power supply is

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.
E.g. The potentiometer can
still control an EC fan via 0-10 V. At the same time, the building management
system can read out the set value of the potentiometer. The building management
can even take control of the potentiometer 0-10 V output if necessary.
series offer fully digital control for AC fan speed
series) via Modbus RTU. Both devices are connected digitally. This
reduces the risk of disturbances and offers the possibility
to increase the cable length between potentiometer and fan speed
minimum and maximum level
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.
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.
potentiometer has a dry contact output. This dry contact output can be used
to control an external device (e.g. damper) or to
enable or disable a motor. When the potentiometer knob is
turned completely counter clockwise, the dry contact is open. When turning
the potentiometer knob clockwise, the contact closes.
