ATEX optocoupler 522 Series

Miniature 522 Series Optocouplers for the galvanic separation of intrinsic safety (EXi) circuits, Isolation voltage min. 4 kVDC, CTR min. 0.5, cutoff 85kHZ, ATEX & IECEx Certified (18 ATEX 0017 U, KIWA 18.009 U). Insulation resistance input /output up to 10^12 Ω. Distance between input and output for highest safety requirements up to 12mm. Galvanic separation and minor coupling capacitance between input and output circuit. Analog & digital signal transfer is possible. Minor output delay times compared to relays. Long life due to non mechanical wear. Magnetic fields do not impact operation. A photo-diode makes for very short cycle times. Able to invert the output signal during transfer. Specifications Isolation Voltage Input/Output Min. (V DC) 4000 Current Transfer Ratio lc/lf (lf = 10mA) Min. 0.5 Turn On/Off Time(µsec) 3.5/2.6 Collector-Emitter Voltage (V DC) Max. 32 Creeping Distance, Air Path I/O Min. (mm) 12 Ambient Temperature °C -40 to 85 Applications Any factory that requires high isolation and non-arcing environments, flammable gas processing plants, medical processing plants where ESD could be a real problem, mining operations
