LJTick-DigitalOut5V

Converts 3.3V digital outputs to 5V digital outputs. Easily control 5V relays, or interface with a 5V logic device. Read more about controlling relays and connecting 5V signals in this app-note.



  • Output only

  • Source or sink up to 80mA

  • Up to 800kHz


Note: When the LabJack digital I/O is configured as an input, the DigitalOut5V accessory will output logic low.

Details

The LJTick-DigitalOut5V (LJT-DO5V) converts a LabJack's 3.3V digital outputs to 5V digital outputs. This allows a LabJack device to control 5V relays or interface with 5V logic devices/sensors.Read more about controlling relays and connecting 5V signals in this app-note.

  • Output only
  • Source or sink up to 80mA
  • Up to 800kHz

Note: When the LabJack digital I/O is configured as an input, the DigitalOut5V accessory will output logic low.

Common Applications

  • Controlling relays that require 5V logic signals.

Screw Terminal Descriptions

VS: This is the same 5 volt output as the VS terminals on the LabJack itself. This is an output terminal, not an input. It can be used to provide 5 volt (nominal) power as needed.

GND: Same as LabJack ground (GND).

DOA/DOB: These lines are the converted 5V logic lines.
