4 Channels Optically Isolated I/O Board Using 6N137 Optocoupler

4 Channel Opto isolated board has been designed around 6N137 Opto-coupler, the 6N137 optocoupler is designed for use in high-speed digital interfacing applications that require high-voltage isolation between the input and output. Applications include line receivers, microprocessors or computer interface, digital programming of floating power supplies, motors, and other control systems.

The 6N137 high-speed optocoupler consists of a GaAsP light-emitting diode and an integrated light detector composed of a photodiode, a high-gain amplifier, and a Schottky-clamped open-collector output transistor. An input diode forward current of 5 milliamperes will switch the output transistor low, providing an on-state drive current of 13 milliamperes (eight 1.6-milliampere TTL loads).

Note : For 3.3 Input Signal R1, R4, R7, R10 = 220E

Features

  • Supply 5V DC
  • Input Signal : 5V DC TTL

  • The pdf download link doesn’t work for the 4 CHANNELS OPTICALLY ISOLATED I/O BOARD USING 6N137 OPTOCOUPLER. Can you advise where I can get a copy of the pdf.
    Do you know anywhere I can purchase the circuit boards.

    Thanks
