Atos control card

E-ME-AC drivers control the current to the solenoids on proportional valves without pressure or position transducer, regulating the spool position, the flow or the pressure according to the electronic reference signal.

• Bias and scale regulations by potentiometers
• Symmetrical or dissymmetrical ramp generator
• Factory pre-sett
• Eurocard format DIN 41494
• 4 Internally generated reference signals
• Electronic filters on in/output lines
• CE marking

Digital electronic drivers E-BM-AS, DIN rail format EN 60715

E-BM-AS digital drivers, supply and control the current to the solenoid of 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 tow single or one double solenoid proportional valve.

• 4 fast plug-in connectors
• RJ45 connector for RS232 Serial communication to program the driver with the Atos PC software
• 4 leds for diagnostics: power supply, driver status, solenoid status (S1 and S2)
• +/- 5 VDC output supply for external reference potentiometers
• Electrical protection against reverse polarity of power supply
• Plastic box with IP20 protection degree
• CE mark to EMC directive.
• Setting of valve’s functional parameters: bias, scale, ramps, dither
• Linearization
• 2 selectable modes for electronic reference
• Max power limitation
• Selectable range of electronic reference
• Complete diagnostics of driver status, solenoid and driver fault conditions
• Intuitive graphic interface

E-ME-L drivers control the current to the solenoids on proportional valves with two transducers, regulating the spool position, or the flow according to the electronic reference signal, adjusted by the feedback.

• Bias and scale regulations by potentiometers
