Instruction manual - EN
To ensure correct operation of the sensors connected to the Analog Node, it is essen-
tial to pay particular attention to the installation of the sensor connectors according
to the analog interface they adopt, following certain combinations.
CONNECTION TO THE TERMINALS
As previously described, it is possible to connect a maximum number of 4 wired
sensors to the Analog Node and each of these must have the same type of analog in-
terface. Therefore a specific Analog Node device cannot be compatible with multiple
types of interfaces at the same time.
In the process of connecting and mechanically installing a sensor with an Analog
Node, it is necessary to pay attention to the type of interface used by the sensor and
the number of wires coming out of the sensor cable. These wires must be manually
connected to the internal terminal of the Analog Node.
The possible configurations can be:
•
4-20mA with 2 wires;
•
4-20mA with 3 wires;
•
mV / V with 4 wires;
•
Pt100 with 4 wires.
Each sensor connection cable will have a variable number of wires with different
colors inside. The intended use and the consequent identification of a cable is ma-
naged through a color coding; thus each conductor is distinguished by a sheath of
a different color:
•
VCC (Power) = Red
•
GND = Black
•
Signal - / = Chromatically variable
To understand the color convention used by a sensor to distinguish the connectors,
consult the product datasheet or contact the supplier company directly.
NOTE
•
The chromatic distinction used in electrical cables may vary according to the
manufacturer. Any operating error resulting from incorrect or improper con-
nection is not attributable to Move Solutions™.

Pt100s usually have two wires of one color and two wires of another color. Arbitrarily
choose one color as “” and one as “Signal -”.
