Note: Our IP0 miniature solenoid valves (except for those using wire connections) have a locationcoding pin, which prevents them from being mounted on our standard subbases. They must only be used with the subbases mentioned on page 8 of this catalogue. If they are being installed with a separate electrical connector, only our connector should be used in order to comply with safety level EEx ia II C T6.

4 Miniature solenoid valves Important These ATEX miniature solenoid valves must be connected individually to an approved safety barrier. Placed in a safe zone, these safety barriers can be used to supply ATEX miniature solenoid valves installed in a hazardous zone. Hazardous zone Safe zone + I max. U source EEx R + ATEX miniature solenoid valve Safety barrier or interface Specifications for loop calculation Vdc Vdc U source EEx < 8 V < 8 V Imax / coil < 7 ma < 7 ma C int 0 0 R at + 0 C 7 Ohm+/7 % 80 Ohm+/7 % R at 0 C > 9 Ohm > 76 Ohm R at + 0 C < 7 Ohm < 690 Ohm U source EEx = intrinsically safe power source at the terminals of the miniature solenoid valve Imax/coil = maximum current through the coil C int = internal capacity of the solenoid valve R = internal resistance of the solenoid valve The electrical connection between the safety barrier (or interface) and the miniature solenoid valve can be made using ordinary wires or cables. The inductance of the connecting line between the safety barrier and the miniature solenoid valve must be less than 0. mh. Recoended barriers and interfaces These safety barriers and interfaces, recoended by CROUZET, should be obtained from one of the manufacturers indicated below, specifying that they are to be used to supply power to miniature solenoid valves Type 8 9, CE 008 ll G, approval no.
