format
Electronic drivers type E-ME-AC
analog, Eurocard format, for proportional valves without transducer
Table G035-11/E
E-ME
AC = for proportional valves
without transducer
01F = for single solenoid proportional valves
05F = for double solenoid proportional valves
Options:
- = standard symmetrical ramp
/RR = with adjustable dissymmetrical ramps
-4 = with 4 reference potentiometers
/RR-4 = with rising and falling ramps and
4 reference potentiometers
/4R-4 = with 4 ramps and
4 reference potentiometers
/I = suitable to receive current reference
signal 4÷20 mA
(not suitable with -4, /RR-4, /4R-4 options)

E-ME-AC drivers control the current to
the solenoid of Atos proportional valves
without pressure or position transdu-
cer, regulating the spool position, the
flow or the pressure according to the
electronic reference signal.
Features:
• bias and scale regulations by poten-
tiometers
• symmetrical (standard) or dissym-
metrical (/RR and /RR-4 options)
rising and falling ramp generator
• factory pre-setted
• Eurocard format (DIN 41494 modular
unit)
• 4 internally generated reference
signals, selectables by external ON-
OFF signals (-4, /RR-4, /4R-4
options)
• electronic filters on input and output
lines
• CE marking granting the conformity
to the EMC Directive (Electromag-
netic Compatibility)
• both sides of the card with shielded
cover with E faston connector
Applications:
Pressure, flow, position open or closed-
loop regulation systems, according to
the block diagram .
