2Introduction
The EvominiSER is a programmable digital transmitter with Modbus RTU output. It can be
connected to different sensors in order to detect different data, such as temperature,
humidity, light etc. Two different versions can be ordered: the EvominiSER I2C, that can be
connected with various supported I2C digital sensors and the EvominiSER RTD, that can be
connected with RTD Pt100/Pt1000 2 or 3 or 4 wire connection.
In this manual the model with I2Cbus input will be mentioned as EvominiSER-I2C (item code
EVO032) while the model with RTD input will be mentioned as EvominiSER-RTD (item code
EVO040 for the model without sensor, EOSI # and ESTP # for models with integrated
sensor).
By using a specific cable, several EvominiSER can be connected in series. One device only
can be a master.
With its small size, low-cost, IP67 degree of protection, easy-cabling and use quality, it is an
extremely interesting equipment for several applications in industrial environment (e.g.,
HVAC systems). Its M12 connectors allow for a fast and easy cabling feature.
Furthermore, by using this transmitter it is possible to implement modular systems. If one
or more devices are to be added to the network, it will not be necessary to design again the
measurement system. Thus, no added design costs are to be sustained.
The Modbus protocol is a very popular standard for field bus applications due to its reliably
and capability of efficiently handling large data flows. With the Modbus implementation, the
Evo series can be hooked up directly to the majority of commercially available PLC’s and
SCADA packages, with the option to connect these modules together with other devices
(PLC’s, operator panels, CNC equipment, etc...) over a single network.
2.1 Working principle
The EvominiSER block diagram is shown in Figure 1.
Figure 1: EvominiSER block diagram
A master unit, e.g., a PLC unit or a PC with SCADA (Supervisory Control And Data Acquisition)
has to be connected to the network for data monitoring.

3Installation
WARNING!
This device must be installed by qualified and authorized people.
3.1 Mounting instructions
A picture of the EvominiSER is shown in Figure 2.
Figure 2: EvominiSER
In order to serially connect several transmitters, a specific M12 tee connector can be ordered
together with its extension cables (for details refer to chapter 7).
A specific sensor can be connected using an M12 connector by screwing it to the metallic
threaded ring. The connection is IP67.
“I2C” is marked on the body of the device to identify the EvominiSER model with input for
digital sensors, “RTD” for the model with Pt100 or Pt1000 RTD input.
3.2 Operating conditions
Installing ambient temperature: (-40÷ +80) °C
Installing ambient relative humidity: (0 ÷ 100) %
Protection degree: IP67 according to IEC 60529
3.3 Electric connections
The EvominiSER comes with two 4-pole M12 connectors. A series connection of transmitters
can be arranged by using an overmolded extension cable with a 4-pole M12 female
connector. Tee connectors are available to extend the network. This solution allows for an
IP65/IP67 connection. It is possible to use other commercially available female M12
connectors. In such a case, the degree of protection depends upon the cabling system.
WARNING!
The electric connections shall be executed as described in the following chapters.
Cabling errors might break either the device or the entire devices’ network.

3.3.1 Power supply requirements
¤ Device power supply: typical 24, or within (9 ÷ 32) range.
¤ Use a power supply with a 24 output, according to ELV regulations.
¤ Maximum current consumption: 10mA (at power-on for about 8 ms).
¤ Average current consumption: about 4mA.
On the power line, insert an insulation switch together with an appropriate fuse. The voltage
supply must be continuous, isolated and with low ripple.
3.3.2 Pinout and connections
The pinout of the output connector is shown in Figure 3.
Figure 3: M12 male output connector pinout
WARNING!
•The device is protected against polarity inversion.
•In case of incorrect electrical wiring, the device is protected only for voltages less than
25. A misconnection with higher voltages will cause a device failure.
The EvominiSER comes with half-duplex EIA RS-485 serial interface. The cabling is simplified
by the M12 connectors

.
WARNING!
The device serial interface is not Galvanically isolated. If the master unit is equipped with
RS232 serial interface, an isolated transceiver should be used. If the master unit is equipped
with RS485 serial interface, a converter with Galvanic isolator should be used. As an option,
a RS485 repeater/isolator can be ordered (cod. EVO005).

Figure 5: application example
3.3.3 Cabling good practices
The RS485 (EIA-485) is a standard defining the electrical characteristics of drivers and
receivers for use in serial communications systems. Electrical signal is balanced, and
multipoint systems are supported. Ideally, the two ends of the cable will have a termination
resistor connected across the two wires. Without termination resistors, signal reflections off
the unterminated end of the cable can cause data corruption. Termination resistor also
reduce electrical noise sensitivity due to the lower impedance. The value of each termination
resistor should be equal to the cable characteristic impedance (typically, 120Ω for twisted
pairs). The master is usually already equipped with the termination resistance. The maximum
length is not defined as depends upon the data rate, the signal-to-noise ratio and the cable
quality.
There are some good practices that allows for external interference reduction. Cables that
carry higher currents to power devices should be kept as far as possible from cables that
carry communication signals. Cables reserved for communication signals must be kept as far
as possible from power switching devices, such as contactors and relays, as well as from
electric motors and generators. Choosing a cable suited for the particular application is also
considered a good practice. In particular, the lower its capacitance per meter the longer the
network can be. Typically, the cable should have a value within the range (50 ÷ 100)pF/m.
The RS485 consists of two conductor cables and twisted pair cabling is suggested to ensure
that each conductor is equally exposed to any external magnetic fields that could induce
unwanted noise. A metallic electrostatic shielding is also suggested to provide immunity to
RF interference.
A star topology network is not recommended. As explained above, a 120Ω termination
impedance is required for the two end line termination devices to avoid reflections. Therefore,
a very low impedance will result from a star topology network. Thus, no communication can
result at a certain point.

IMB222 Rev.4.05 May 2022

3.3.4 Polarity
According to RS485/422 standard, the signal connections are indicated with A and B.
However, it might be possible to find different indications on some products, such as HI/LO
or +/-. If a device is unable to connect to the network, try inverting A and B and to connect
the device again.
3.3.5 Terminating impedance
Signal reflections occur when a signal is transmitted along a transmission medium, such as
a copper cable. Some of the signal power may be reflected back to its origin rather than
being carried all the way along the cable to the far end. This happens because imperfections
in the cable cause impedance mismatches and non-linear changes in the cable
characteristics.
The signal reflections can be canceled by adapting the terminal impedance, whenever it is
necessary. If the time required for a single bit transmission is, at least, ten times the signal
propagation time on the network, the terminating impedance is not necessary.
The value of cable impedance depends on its dielectric material and mechanical dimensions.
The velocity of propagation in PE cable is about 2/3 the speed of signal if the dielectric cable
was vacuum. Therefore, the propagation time is:

  
 
For example, for 9600baud and 1200m of cabling, =6µs. The time required for a single bit
transmission is:
 
󰇛
󰇜

 
Thus, in this example, the terminating impedance is not strictly necessary. However,
whenever the terminating impedance is required, a resistor must be inserted in the last node
(from the master) between terminal A and B (pin 2 and pin 4 in the M12 connector). Its
value must be equal to the cable impedance. In typical applications, the terminating
impedance has only resistive components and its typical values are in the range 120Ω to
560Ω, depending on the cable and number of nodes on the network.
3.3.6 Allowed maximum number for series connected transmitters
The maximum number of transmitters that can be connected in series is dependent upon
the connection length and cable parameters.
A calculation worksheet that indicates to the user the maximum number of devices that can
be connected to an EvominiSER network given the cable cross-section (i.e., AWG) and cable
length is available. It is downloadable from the website products.italcoppie.it (EvominiSER
network data)
For example, with a 24 voltage supply and a 300m cabling:
-AWG20: up to 60 devices
-AWG22: up to 45 devices
-AWG24: up to 35 devices
The given indications refer to the given power supply. The RS485 transceiver can support
up to 256 nodes, but it is suggested to place isolators/repeaters along the serial line. If the
power supply cabling is longer than 100 meters, it is strongly suggested to use a MLCC
capacitor (1000pF, 1kV; for example, RDE5C3A102J2M1H03A) connected between GND of
the power supply and GND of the plant: this one is connected the cable shield.
