DEVICE OVERVIEW
NI2400 is a universal datalogger, capable of reading 0..25mA Current Loop and
Transmitter, -10..10V, Vibrating Wire, NTC, PT100, PT200, PT500, PT1000, Ratiometric,
Wheatstone Bridge, Thermocouple, Potentiometer and SmartModbus RS-485 Digital
Sensors.
It provides a maximum of 24 channels when using only 2 wires sensors.
NI2400 is expandable with SmartMux device.
Connections
Front Panel
Figure 2
The majority of connections are located In NI2400’s front panel:
• RS-232: it can be used to connect a 3G Modem to expand connectivity
• Ethernet: This port is used to connect the device to an existing LAN. Internal Web Server
can be browsed to configure and download acquired data. It can be used for Internet con-
nection (Cloud, FTP and EMAIL connections)
• USB Host: it allows the user to download measures, events and alarm logs to a pendrive,
or to update the firmware
• V OUT: this connector is designed to output the same voltage applied to V IN. It can be
turned off automatically when logger is in sleep mode or be kept always on.
• RS-485#2 – V OUT: This is SmartMux port, which allows the connection of 16 SmartMux
in daisy chain and offers power supply.
• RS-485#1 – V OUT: This is SmartModbus port, which allows digital sensors connections
and offers power supply.
• V IN: This port is to power the datalogger. It’s designed to work in 10-30V range.
• PWR-CONFIG: This port will allow the selection of Power supply. A jumper between two
rightmost connections is needed to let the datalogger be powered up.
• ANALOG INPUTS: This 8 terminal blocks is used to connect analog sensors. Starting from
bottom-left to bottom-right we find channels from 1 to 12, and from top-left to top-right
we find channels from 13 to 24.Every 6 connections, there is a Ground connector designed
to be the termination of shielded cables.
