470 Parker Hannifin Corporation Fluid Control Solutions Europe General Catalogue FCSE/0112/UK V2.2 07/2022 EXPLOSION PROOF ELECTRICAL PARTS ZONE 0/20 INTRINSICALLY SAFE ELECTRICAL PARTS "ia" 488650.01 & 490885 "NEMA" ELECTRICAL PARTS "IS" 50 mm This coil can be mounted with every Parker ATEX solenoid valves corresponding to the specified Coil Group. See column "Coil Group" within valve pages. Application: Control of solenoid valves in dangerous areas where explosion-proof protection Ex ia IIC - T6 is required. Benefits: Rotatable 360° housing, polyamid with fibreglass housing and cover. Coil, electronic circuits and other elements required for intrinsic safety are completely encapsulated in the housing with epoxy material for shock and corrosion protection. Small size for ease of mounting in confined space. To Order a Coil choose Coil Ref + Voltage Code, example: 490885 for 30VDC = 490885L8 Important The intrinsically safe supply circuit should have enough capacity in all environmental conditions to assure a minimum operating current of 29 mA through the coil. The minimal holding current is 20 mA. For the barrier compatibility see the corresponding table in appendix section.
