Additional specifications and description
This
is a 0-10 V
potentiometer
0-10
V potentiometer with 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.
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.
Modbus
RTU
potentiometer
SPV
series offer fully digital control for AC fan speed controllers (RTVS1 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
controller.
Adjustable
minimum and maximum level
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 ispossible 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!
Different
output
types
The
output type of this potentiometer can be selected via Modbus RTU: 0—10
V, 0—20 mA or 0—100 %
PWM.
