Electronic drivers type E-RP-AC
analog, sealed and rugged box, for proportional valves without transducer
Table G100-11/E
E-RP-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
• 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 (Electromagne-
tic compatibility)
Applications:
Pressure, flow, position open or closed-
loop regulation systems, according to
the block diagram .
