OUTPUT INPUTS
Electronic drivers type E-MI-AC
analog, DIN 43650 plug-in format, for proportional valves without transducer
Table G010-15/E
E-MI-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 with IP65 protection
degree
• electronic filters on input and output
lines;
• CE marking grating the conformity to
the EMC Directive (Electro ma gne tic
compatibility).
Applications:
Pressure, flow, position open or closed-
loop systems, according to the block
diagram .
