Multiplexer board product allows you to expand the number of analog acquisition channels of the NI2400 and NI100 data logger with further 24 channels.


The data logger operates the product directly by utilizing the Modbus protocol to select the desired analog channel for acquisition through appropriate commands.

These commands establish a physical analog connection between the sensor and the data logger.

The product comprises two boards, namely M3791 and M3792, which are interconnected with a flat cable.

M3791 serves as the sensor connection board, while M3792 serves as the digital data logger interface and routing analog board.

The multiplexer board is equipped with a keyboard consisting of DIP Switches. Furthermore, the smart monitoring systems allow for the expansion of analog channels, enabling up to 16 multiplexer boards to connect to NI2400 and NI100.
