E-BM-AS
Digital drivers control the current to the
solenoid of Atos proportional valves without
transducer, according to the electronic
reference input signal.
The solenoid proportionally transforms the
current into a force, acting on the valve
spool or poppet, against a reacting spring,
thus providing the hydraulic regulation.
E-BM-AS can drive up to two single or one
double solenoid proportional valves.

Electrical Features:

• 4 fast plug-in connectors
• RJ45 connector for RS232 Serial com-
munication to program the driver with the
Atos PC software
• 4 leds for diagnostics (see section
• ±5 V output supply for external referen-
DC
ce potentiometers (/P option)
• Electrical protection against reverse pola-
rity of power supply
• Operating temperature range: -20 ÷ +60 °C
• Plastic box with IP20 protection degree
and standard DIN-rail mounting
• CE mark according to EMC directive

Software Features:

• Intuitive graphic interface
• Setting of valve's functional parameters:
bias, scale, ramps, dither
• Linearization function for the hydraulic
regulation
• 2 selectable modes for electronic reference
signal: external analog input or internal
generation
• /W option max power limitation function
• Complete diagnostics of driver status
