4 CHANNEL OPTO-ISOLATED MODULE USING HIGH SPEED 6N137 OPTOCOUPLER

Summary of 4 CHANNEL OPTO-ISOLATED MODULE USING HIGH SPEED 6N137 OPTOCOUPLER


The article describes a 4 Channel Opto Isolated Board built around the 6N137 optocoupler, designed for high-speed digital interfacing with high-voltage isolation between input and output. It is suitable for line receivers, microprocessors, and control systems. The 6N137 incorporates a GaAsP LED and an integrated light detector, enabling an input forward current of 5mA to switch the output with a drive current of 13mA. The board operates at 5V DC with TTL input signals and includes header connectors for inputs and outputs along with a power LED indicator.

Parts used in the 4 Channel Opto Isolated Board:

  • 6N137 Optocoupler
  • Resistors (R1, R4, R7, R10 - 220Ω for 3.3V input signals)
  • Power LED (D1)
  • 5V DC Power Supply
  • Header Connectors for Inputs
  • Header Connectors for Outputs

4 CHANNEL OPTO-ISOLATED MODULE USING HIGH SPEED 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
