Electronic drivers type E-BM-AC
analog, DIN 43700 UNDECAL fast plug-in, for proportional valves without transducer
Table G025-4/E
E-BM-AC drivers control the current to
the solenoid of Atos proportional valves
without pressure or position transducer,
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 option) rising and fal-
ling ramp generator
• factory pre-setted
• alluminium box (DIN 43700 modular
unit)
• can be mounted on back panel DIN
guide or on front panel
• power supply 24 V
DC or 12 VDC (/12
option)
• electronic filters on input and output
lines
• CE marking granting the conformity
to the EMC Directive (Electromag-
netic Compatibility)
Applications:
Pressure, flow, position open or closed-
loop regulation systems, according to
the block diagram .

E-BM
E-BM = electronic driver
Fast plug-in format
AC = for prortional valves
without transducer
01F = for single solenoid proportional valves
011F = for two single solenoid proportional valves
05F = for double solenoid proportional valves
Notes:
- the reference R2 must be supplied only for E-BM-AC-011F
- with the version 011F it is possible to regulate two-single solenoid proportional valves also contemporary
Options:
- = standard symmetrical ramp
/RR = with adjustable dissymmetrical ramps
