467 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" 495910 - MINIWATT - 0.3 W ELECTRICAL PARTS "IS" "BOOSTER" 37 mm These coils 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 T4 to T6 is required. Benefits: Rotatable 360° fibreglass-reinforced plastic housing (class H). Solenoid coil, rectifier (silicium diodes), fuses and varistor protection are completely encapsulated into the coil housing by epoxy resin for shock and corrosion protection. Small size for ease of mounting in confined space. Available only in 28 VDC (code: N7). To Order a Coil choose Coil Ref + Voltage Code, example: 495910 for 28 VDC = 495910N7 Reference 495910 Certificate LCIE 03 ATEX 6464 X - IECEx LCI 07.0006 X Coil Group 8.0 Type of protection Gas II 1 G - Ex ia IIC - T4 / T5 / T6 Dust II 1 D - Ex ta IIIC T80 / 95 / 130°C Degree of protection IP67 according to IEC/EN 60529 Standards Ambiant temperature - 40°C to +80°C / 75°C / 65°C The application is limited also by the temperature range of the valve.. Class of insulation H 180°C Electrical connection Electric connection is done in the connection box on an easily accessible connector terminals. The introduction of the cable (Ø min 7 mm, Ømax. 11 mm, section max. 2.5 mm²) in the connection box passes by the built in M20 x 1.5 cable gland Maximum supply voltage 28 VDC (N7) - 110 mA Power DC Minimum 0.3 W (with 13 VDC) Maximum 1.2 W (with 24 VDC) Depending on applied voltage, IS barrier type and resistance of connected cable Line check 4 mA or 5 VDC max Coil resistance at 20°C Impedance Apparent inductance Apparent capacitance Charge ~ 550 Ω - Holding ~ 500 Ω 0 mH 0 µF Response time 2 - 3 s Weight 500 g 8.0 COIL GROUP
