ALLDAQ ADQ-153 ADQ-Box-I2C-MUX

ALLDAQ I2C multiplexer, buffer, isolator, level shifter

With the I2C multiplexer boxes from ALLDAQ you have numerous possibilities to expand your I2C structures and make them more run-sensitive.

I2C Multiplexer: An I2C master channel is generated via USB, which is directly available and additionally addresses an integrated multiplexer module. This I2C bus is then extended to up to 3 additional channels. The multiplexer has 8 switchable I2C addresses, so that other boxes can be used simultaneously and several slaves with identical I2C addresses can be used.

I2C Verlängerung: In addition to the conventional I2C bus, the ADQ-I2C modules also offer specially buffered interfaces. Thus, 2 boxes can be used as an extension to cover distances of several 100 meters over a 2-wire twisted pair cable.

I2C Isolator: The buffered SCL/SDA lines are capacitively isolated to provide protection against ground loops, for example, if the GND reference of the terminals differs such as when using long cables.

I2C Level-Shifter: The internal pull-ups at 5V can be switched off by software. Thus, external pull-ups can also be used to work with other voltage levels
