Photologic® Optically Coupled Isolator OPI125, OPI126, OPI127, OPI127-032, OPI128 Applications:

  • High voltage isolation between input and output
  • Electrical isolation in dirty environments
  • Industrial equipment
  • Medical equipment
  • Office equipment Description: Each OPI125, OPI126, OPI127, OPI127-032 and OPI128 consists of an optically coupled isolator with a gallium arsenide infrared emitting diode coupled to a monolithic integrated circuit. This circuit incorporates a photodiode, a linear amplifier and a Schmitt trigger on a single silicon chip. For maximum long-term stability, both the diode and the Photologic® sensor are hermetically sealed in separate packages and then mounted in a high dielectric plastic housing. These devices feature TTL/LSTTL compatible logic level output that can drive up to 8 TTL loads directly without additional circuitry. Also featured are medium-speed data rates to 250 KBit/s, with typical rise and fall times of 70 nanoseconds. *UL recognition is for 15KVDC to 100° C. TX and TXV processing is available. For more information, contact your local representative or OPTEK. Features:
  • Four output options
  • 15 kV input-to-output isolation voltage
  • Direct TTL/STTL interface
  • High noise immunity Product Photo Here RoHS
