Features
The EDM-M is a digital card suitable for the control of one proportional valve with two
solenoids (M2 version) or one/two independent proportional valves, also pressure or throttle,
with one solenoid each (M1 and M3 versions).
It is designed for rail mounting type DIN EN 50022.
The card supplies the current to the solenoid according to the reference signal and
independently of temperature variations or load impedance.
The card uses micro USB interface, and via software EBC configurator it is possible to set
parameters.
-100% compatible with previous version 20
-Micro USB connector:
no serial converter required
optionally board supplied by USB for programming (valve use disabled)
-Separate PWM settings (PWM-Dither) in the 2-channels version EDM-M3
-Enable signal (version A only)
-Parameters programmable via software:
Ramps, deadband compensation, scaling of analogue inputs
-Fault recognition (cable breaks, short-circuits, etc.)

SIGNAL_OFFSET and SIGNAL_GAIN parameters.
M1 version (for one valve with one coil) require unipolar voltage (0…10 V) or current signal
(4…20 mA)
M2 version (for one valve with two coils) generates a proportional current on solenoid A with
a positive value of voltage or a current between 12…20 mA and a proportional current on
solenoid B with a negative value of voltage or a current between 4…12 mA.
M3 version (for two valves with one coil each), requires that both the analogue inputs must be
used.

Installation instructions
This module is designed for installation in a shielded EMC housing (control cabinet).
All cables which lead outside must be screened; complete screening is required. It is also
necessary to avoid strong electro-magnetic interference sources being installed nearby when
using our open and closed loop control modules.
Typical installation location: 24 V control signal area (close to PLC)
The devices must be arranged in the control cabinet so that the power section and the signal
section are separate from each other.
Experience shows that the installation place close to the PLC (24 V area) is most suitable. All
digital and analogue inputs and outputs are fitted with filters and surge absorbers in the
device.
The card must be installed and wired according to the EMC 2014/30/EU directive rules.
If other consumers are operated with the same power supply, a star-shaped ground wiring
scheme is recommended.
The following points must be observed when wiring:
•0V DC of the power supply must be connected to the GND on electrical cabinet.
•The signal cables must be laid separately from power cables.
•Analogue signal cables must be screened.
•All other cables must be screened if there are powerful interference sources
(frequency converters, power contactors) and cable lengths > 3 m. Inexpensive SMD
ferrites can be used with high-frequency radiation.
•The screening should be connected to PE (PE terminal) as close to the module as
possible. Local requirements for screening must always be taken into account. The
screening should be connected to at both ends. Equipotential bonding must be
provided where there are differences between the connected electrical components.
•If having longer lengths of cable (> 30 m), the diameters and screening measures
should be checked by specialists and if necessary please consult the manufacturer (e. g.
for possible interference, noise sources and voltage drop). However, the sizing must
ensure a voltage to the coil of not less than 90% of its nominal voltage.
•the value of the power supply voltage on the card must not be lower than the rated
working voltage of the solenoid to be controlled.
•Provide a low-resistance connection between PE and the mounting rail. Transient
interference is transmitted from the module directly to the mounting rail and from
there to the local earth.
It is recommended using a regulated power supply (linear or switching mode) for card supply
and for the sensors.

WARNING! Plugs with free-wheeling diodes and LED indicators cannot be used with
current controlled power outputs. They interfere with the current control and can
destroy the output stage.
Switched inductances (relays and valve coils) which are connected to the same power supply
must always be provided with appropriate overvoltage protection directly at the coil.
The 15-poles terminal strip accepts connections of a 1.5 mm² conductor with ferrule.
Applications that require larger cross sections require mandatorily a junction box.
WARNING! Engage the terminal block ONLY with the panel switched off.

Card Setup
Card configuration occurs only by EBC software from a PC or by EBC app. Anyway, cable
connection with the card is always necessary.
All the ancillary equipment is available as separate kit.
EDMPC/30 kit
It includes a USB communication cable (micro USB-B male - USB A male) of 3 meters length, 2
adapter cables for smartphones OTG USB2.0 and OTG USB3.0, in order to cover the widest
devices compatibility range, a USB key with EBC software pack for notebook, to be installed.
Ordering code 3898201020.
EBC App
This app has been developed in order to offer immediate diagnostic and configuration
activities of USER level parameters of electronic cards even in the field, with a traceability
function that makes service operations more efficient.
The app requires Android devices that support OTG function (Usb On-The-Go) and can be
downloaded from the Google Play store.
Use the communication cable and the suitable adapter in the EDMPC/30 kit to connect the
smartphone to the card.
On-line registration is required at first access. Once registered the app can even work off-line.
The EBC app allows diagnostic and configuration activities of USER level parameters. Password is
required to apply parameters changes. See Parameters section.

page 16 of 29 Duplomatic MS S.p.A. ▪ EDM-M*/30 Start-up Manual ▪ 89251/218 ETM ▪ Jun 2018
EBC configurator software
This is the software for EDM-M parameters configuration.
EBC software is a graphical interface for digital communication, diagnostic tasks and
parameterization.
In addition to the features available on the app, it offers advanced diagnostic programs and an
oscilloscope with measure functions, and allows to save and import parameters sets, as
needed for fast card replacement and for the reduction of start-up time of the system.
The software is distributed inside the EDMPC/30 kit and is also available for download at:
http://www.duplomatic.com/en_US/download/software-download/
System Requirements & Settings
The EBC software can be installed on every machine equipped with Microsoft OS: Windows 7,
8 and 10, a free USB port to connect the communication cable (standard cable type USB A –
micro USB B).
Launch the setup file and follow the guided procedure to install the program and USB drivers.
Complete driver setup and restart the machine if requested before connecting the module to
the PC.
At the end of installation, a security alert could appear, asking to define permissions for
firewall, depending on your OS and notebook configuration.
See software literature (inside software pack) for EBC configuration software.
Please note that for programming purposes, the EDM card can be powered directly through
the USB port. Leds blink all together for signalling the USB communication.
If you need to energize the valve simultaneously, you need the power supply to pins 1/2.

With ENABLE = INT, the card enables the output power stage automatically after the power-on
(with a delay time of approx. 0.5s).
This parameter is available only for A version of EDM-M card.

Signal scaling example:
With an EDM-M2**/30E0-* the available signal type is -10…0…+10V.
If application signal is 0…2.5…5V this means:
▪0% signal for the valve must be moved from 2.5V (application 0%) to 0V - >
SIGNAL_OFFSET = Standard Offset –Application Offset = 0 - 2.5 = - 2.5 V
▪Signal input must be scaled from 2.5V to Standard Full Scale of 10V - >
SIGNAL_GAIN = Standard F.S. / Application F.S. = 10 / 2.5 = 4.0
