High-voltage UL-certified Optoisolator Targets ATEX-ICEex Apps

Tue, 01/25/2011 - 5:25am
high voltage optoisolatorTT electronics OPTEK Technology has developed a UL- and VDE-rated optical isolator with 20 kV isolation and 2Mbit/s data transmission rates designed to comply with ATEX and ICEex certifications for electrical equipment used in hazardous areas, as well as IP65 standards for environmental sealing. Designated the OPI1268S Series, the high speed optoisolator is designed for high voltage power isolation in applications requiring sealing against dust and liquids, as well as in electrical equipment in potentially explosive atmospheres, such as transportation systems, hybrid vehicles, medical devices, and industrial control/safety systems. The OPI1268S Series optoisolator is comprised of a high-efficiency GaAIAs (Gallium Aluminum Arsenide) LED with a peak wavelength of 850 nm, optically coupled to a photodiode that detects incoming modulated light and converts it to a proportionate current. The device’s high-gain linear amplifier is temperature-, current-, and voltage-compensated, resulting in a stable digital output with an open collector inverter configuration that delivers DC and AC voltage isolation between the input and output circuitry while providing TTL signal integrity with a data transfer rate of 2 Mbits/s.
