Digital electronic drivers

type

E-MI-AS-IR

DIN 43650 plug-in format, for proportional valves without transducer

Table

G020-7/E

E-MI-AS digital drivers are designed for

mounting on the solenoid’s DIN connector

of proportional valves without transducer.

They supply and control the current to the

solenoid according to the electronic refe-

rence input signal. The solenoid propor-

tionally transforms the current into a force,

acting on the valve spool or poppet,

against a reacting spring, thus providing

the valve’s hydraulic regulation.

E-MI-AS drivers can drive single or dou-

ble solenoid proportional valve.

Electrical Features:

• Standard 5m cable connection

M12 connector (/M12 option)

• Infrared communication interface

rence potentiometer (not available for
/M12 option)

• Current reference input (/I option)
• Plastic box with IP65 protection degree

and standard DIN43650 plug-in format
with double earth connection to allow
double-side orientation

• CE mark according to EMC directive

Software Features:

• Setting of valve’s functional parame-

ters: bias, scale, ramps, dither

• Linearization function for the hydraulic

regulation

• 2 selectable modes for electronic refe-

rence signal: external analog input or
internal generation

• Max power limitation (/W option)
• Selectable range of electronic referen-

ce analog input: voltage or current
(/I option)

• Complete diagnostics of driver status,

solenoid and driver fault conditions

• Intuitive graphic interface
