User’s Manual
The DIVIT device acquires voltage or current signals on four different channels galvanically isolated from
each other and the power lines. They can be used with 0..5V or 0..10V voltage signals, or in 0..10 or
0..20mA current loop. Each independent channel can be associated with a reading magnitude by setting
appropriate parameters for the corresponding measured electric/magnitude signal values of two known
characteristic points; correspondence should be linear. The value of the measured magnitude is
transmitted directly. The format of the data transmitted has an absolute dynamic ranging from -273 to
+1735 with selectable decimal point position. A descriptive alphanumeric string can be set for each
channel on the SICES DST4601/PX boards, and the unit of measure of the magnitude measured by the
sensor defined in it. Both active and passive sensors can be used.
The device is available in two versions, with CANBUS or MODBUS RS485 communication; both versions
have galvanically isolated communication lines. A further (non isolated) RS232 connection is available
via Jack to configure the device. Connection with SICES boards is via CANBUS, with dedicated EXBUS protocol.
The device has an output connector for controlling the optional SICES E610209350XXX, DITEL
MODULE 8 OUTPUTS, either at 12V or 24V. Through it you can control eight dry contact relay outputs,
activated through thresholds and conditions set with parameters using an RS232 serial port (JP
connector) and the SICES BoardPrg program.
The device can be installed on a DIN guide.

0xFAFF
Reading value = [(Ex-bus value) / 32] - 273

0xFAFF = Overflow,
0x0000 = Underflow,
0xFF00 = unavailable,

0xFE05 = current under threshold
0xFE06 = current over threshold
Diagnostics. Contains: board type, firmware
revision, CAN error counters, alarm states.
Transmission freq.: 1 sec.
Note: each module transmits with a single ID. The ID selection is made with SWN switches 1-4
(EX-BUS ADDRESS). To change the EX-BUS address, after modifying the switches, turn the DIVIT
module off then on again.
For further information on EX-BUS protocol, refer to EAAS0346xxxx specifications.
Enabling this function lets you automatically calculate and transmit the difference between the readings
acquired from input 1 and input 2 (then M3 = M2 - M1). In this case the sensor connected to input 3 (J7)
will not be detected.
ALARM3 Led flashes rapidly to indicate the function is activated and the reading is estimated. The result
of the difference is taken as a normal reading, so it is transmitted instead of the reading from input 3 and
can be associated with conditions and thresholds. If inputs 1 or 2 are invalid, M3 will also be invalid. This
function is activated by parameter.
The conditions allow flexible programming of the thresholds for activation of the relays. Parameter can
be set for up to 8 conditions. You can associate 2 or more conditions by setting the same OUT and
indicating whether they operate with OR or AND logic.
The following can be set for each condition:
-
Input N.: if set to 0 deactivates the entire condition, from 1 to 4 selects the analog input to take
the reading from for the control.
-
Out N.: if 0 no OUT is modified by this condition, the value from 1 to 8 selects the relay output to
use (if the condition is verified, this output will be activated, otherwise it will be deactivated). Note:
the OUT is under the full control of the condition and cannot be modified via Modbus.
- Activation threshold and delay: When the measured value exceeds this threshold for the time
indicated, the condition is activated (positive logic).
8
User’s Manual
- Deactivation threshold and delay: When the reading value falls below this threshold, and remains
so for the time indicated, the condition is deactivated (in positive logic). If the delay is 0, the
deactivation threshold is disabled: in this case the condition is disabled when the value drops
below the activation threshold.
- OUT state on reading invalid or sensor fault. If the input selected by this condition is outside the
declared limits or the reading is invalid, this parameter indicates the state the output must be in:
0= not forced, 1= forced deactivated (OFF), 2= forced activated (ON).
- And/or logic on previous conditions that use the same OUT.
The thresholds can function in positive or negative logic:
POSITIVE LOGIC: activation threshold >= deactivation threshold (e.g.: activation threshold = 8.5 Bar,
deactivation threshold = 8.0 Bar  the relay is normally open; when the pressure reaches 8.5 bar the
relay is closed, and remains so until the pressure drops below 8.0 bar again).
POSITIVE LOGIC

( Sa > Sd )
Sa = Activation threshold
Sd = Deactivation threshold

NEGATIVE LOGIC: activation threshold < deactivation threshold (e.g. activation threshold = 20%,
deactivation threshold = 50%  the relay remains closed as long as the percentage reading is below
20%. The relay opens when the reading is above 20% and remains open until the percentage drops
below 50%)

8 RELAY MODULE
Max. current rating of relays: 4A.
Weight of 8 relay module: 150 g
The 8 out relay board doers not require a power input; it should be connected to the DIVIT module using
a 10-pin flat cable connected to connector J5. Position the two modules so the flat cable is as short as
possible.
Each output has an indicator LED. The leds light when the corresponding output is active, in other words
when the contact closes between COM and NO.
The outputs can be controlled by the conditions set in the parameter, or via Modbus. The out controlled
by the conditions cannot be modified via Modbus.
8 relay module version available:
8 OUTPUTS 24V MODULE.
E610209350000
For systems with 24V (18-30 VDC) power supply
8 OUTPUTS 12V MODULE.
E610209350100
For systems with 12V (9-16 VDC) power supply
The configuration requires connection to a PC via RS232 serial port using Jack connector JP or RS485
serial with connector J2 and the BoardPrg program (version 2.25 and later).
BoardPrg can be downloaded from the site www.sices.biz in the Software section  Sices Board
Programming (select the latest version BoardPrg_x_yy_z.msi).
Notes: Use cable E090000000142 (RS232-E20931 module connection cable) to connect via
a RS232 serial port (JP Jack connector).

10
Set the serial port to be used on the PC (in Communication Menu  Select Communication
Resource). Check the communication parameters: 9600, N, 8, 1
User’s Manual

Set the Modbus address (in Communication menu - Serial address: default = 1)

Display the parameter window (in File menu  Parameter management)

Make the connection to the DIVIT board (Connect).
Important: Read the parameters (Read command), and transfer the values to the New Value
column, where you can edit them (Copy command).
Now you can configure the device.
After configuration, check SWE dipswitch 8=ON and press Transmit.
The configuration can be saved on a PC (Save), and reloaded (Load) at a later date to configure other
modules in the same way.
After programming, switch SWE dipswitch 8 OFF again to activate write protection.
SWA, SWB, SWC and SWD switches 1 set the end-of-scale for each channel, switches 2 are not used:
SWA, B, C, D
ON = 10 mA / 5 V
OFF = 20 mA / 10 V
Once you have set the switches, adjust the parameters.
By default, no channel is enabled and none of the four readings is transmitted.
Set the type of electrical signal (current or voltage) and its end-of-scale value for each channel used.
Select in the drop down menu under "Input type" in the pages of the 4 inputs of the BoardPrg program.
You can set the limits of acceptability of the signals from the sensors: these are the lower and upper
thresholds for reporting sensor faults. Values are expressed as a percentage and refer to the current or
voltage reading. E.g.: if we have a 4-20 mA signal, the input will be configured for 0-20 mA; we can set
20% as the lower threshold and 100% as the upper threshold so if the sensor signal is below 4 mA or
above 20 mA a fault will be reported (sensor faulty or disconnected).
User’s Manual
11
Independently for each channel you can set the correspondence between the electrical magnitudes
(current and/or voltage) at the module inputs and the physical magnitudes (pressure, speed, levels ...)
detected by sensors or other devices. We need to know two points on the sensors characteristics, which
must be linear. The configuration parameters can be found in the inputs pages. Enter the value of
physical magnitude and the corresponding electrical signal for each channel.
For example, if on channel 1 there is a pressure sensor for which the points 2 and 8 bar correspond to
6 and 10mA are known, enter the value 6 in the "Input value 1" box and value 2 in the box "Corresponding
value 1 transmitted". Then enter values 10 in the "Input Value 2" box and 8 in the "Corresponding value
2 transmitted" box. The channel has now been configured.
The maximum limit of the transmitted value is 1735 units; using values with decimals and choosing
multiples or sub-multiples of the unit of measure of the input magnitude, any value can be transmitted.
For example, to transmit a pressure from 1000Pa to 7000Pa choose the "corresponding values
transmitted" 100.0 and 700.0 hPa (hectopascals) as the unit of measure.

The device is designed to be mounted on a DIN 46277 guide in an upright position. It requires adequate
ventilation to function properly. Avoid installing above and/or near devices that produce heat.
Only use screened cable to connect to the reading inputs; connect the screen at a ground point
near the input connectors.
For an RS485 connection, use a screened cable with an 120 ohm impedance; for CANBUS
connection, use the appropriate cable, e.g. KELUKABEL 800571
RS485/CANBUS terminations: to minimize reflections, the first and last device in the RS485 or
CANBUS network must have a termination resistor connected in parallel with the 120 ohm ½ W line.
