Electronics - Atos EMIAC

E-MI-AC electronic drivers supply solenoid proportional solenoids type ZO(R)-A with the correct current signal to align valve regulation to the reference signal.

They are designed to operate in open-loop electronic systems for Atso proportional valves without integrated transducer. The driver are supplied with integrated connector according to DIN 43560. The driver operates the valve's regulation proportionally to the input reference signal (voltage or current) supplying a switching current to the solenoid. Scale and Bias adjustments, for accurate valve regulations, are available via built-in potentionmeters. The driver is normally used with a reference signal supplied by an external set-point potentiometer or by PLC control unit and a symmetrical rising and falling ramp generator. The electronic drivers includes CE marking granting conformity to the EMC directive (Electromagnetic Compatibility).

Option /RR = With adjustable dissymmetrical ramps. Suitable also for current signal 0-20 mA.
