Technical Data of the Solenoid Nominal voltage: Nominal current: Input Power: Stroke: Type of Protection ATEX: EEx ia II C T5/T6 ~ 11 VDC ~ 46 ma ~ 0.5 W 2 mm Description of the Solenoid The solenoid used for the electric actuation of the valves consists of a solenoid with a diode safety barrier (three diodes in parallel-circuit). The solenoid and the diode safety barrier are completely molded in sealing compound. The maximum current of the external is (intrinsical safe) circuit is 660 ma and the connection of this is circuit is made by a plug mounted onto the enclosure. The solenoid can be equipped with an electronic device to reduce the current while still energised. Page 1/2
