535 Series Optocouplers for the galvanic separation of intrinsic safety (EXi) circuits, Isolation voltage min. 4kVDC, CTR min. 3.0, cutoff 2kHZ, ATEX & IECEx Certified (18 ATEX 0017 U, KIWA 18.009 U). Insulation resistance input /output up to 10^13 Ω. Distance between input and output for highest safety requirements up to 14.5mm. 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.
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
