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.)

Available versions
EDM-M z xx hh /30 Ey- k
The functionalities of the module can be chosen by the proper ordering code, where:
-Zis the type of valve / valves to be driven.
1 - single valve with one solenoid
2 - single valve with two solenoids
3 - two valves with one solenoid each, (separate channels, EDM-M3 can manage even
two different type of valves)
-X indicates the nominal current required.
Two digits - XX - appear in M3 version only, because of the separate channels which
require entries for each coil.
Please note that option 5 is not settable for the 2nd channel, so if you have a coil with
this requirement link it with the 1st channel.
1 –860 mA
2 –1200 mA
3 –1600 mA
4 –1880 mA
5 –2600 mA
-Hindicates the choices for PWM frequency
Two digits - HH - appear in M3 version only, because of the different PWM value that
each solenoid requires.
1 –100 Hz
2 –200 Hz
3 –300 Hz
4 –400 Hz
-Yindicates the type of reference signal
0 = reference signal in voltage 0…10V or ±10 V depending on Zchoice,
1 = reference signal in current 4…20 mA
-Kindicates PIN12 setting as digital INPUT or digital OUTPUT
A = Pin 12 used for external enable (Non-existing configuration in previous series 20)
B = Pin 12 used for V aux (internal enable) - Series 20 compatible.

Proper parameters of maximum current, PWM, dither and set the output supplied to

Separate parameters are available for each output channel in EDM-M3 card version (two
valves with single solenoid)
Moreover, the output value can be compensated using the deadband compensation
parameter set.
The maximum current that can be provided to a coil is 120% of the CURRENT parameter.
The upper limit of CURRENT is set by CURRENT_LIM parameter and it can’t go over the
maximum current of 3600 mA for the output a 2600 mA.
Analog input
Analog inputs type can be selected by SIGNAL_TYPE parameter and signals can be scaled by
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.
