NI2400_DS

Product catalog summary

General Specifications:
The NI2400 is a 24-channel Ethernet data logger with an embedded web server. It supports various input types including thermocouples, PT100 RTD, NTC thermistor, mV, mA, and mV/V. It features a web server for real-time data viewing and storage in a 2GB internal memory. The device offers Ethernet, RS485, RS232, and USB connections, and supports SMS and email alerts. It is expandable up to 384 channels with multiplexers.

Physical Characteristics:
The device weighs 980g and measures 231 x 138 x 117 mm. It is constructed from plastic and metal and uses removable screw terminal connectors for wiring.

CPU and Memory:
Equipped with an ARM Cortex-M3 MCU, the NI2400 has 1 MB Flash and 1 Mbyte RAM. It includes a 2 GB SD card for data storage and features a high precision RTC with battery backup.

Analog Inputs:
The NI2400 has 24 differential analog inputs, configurable for 2 to 6-wire sensors. It supports current loop, transmitter, voltage, servo inclinometer, Wheatstone bridge, and potentiometer input types. The device offers a measurement accuracy of 0.01% FS and supports a range of thermocouple types with specified error margins.

Digital I/O:
Includes one relay output and two opto-isolated digital inputs. The digital output is suitable for low voltage applications, and the inputs support a maximum voltage of 24V.

Interfaces:
Features a small backlight graphic LCD and membrane keyboard for local management. It supports Ethernet, RS232, USB, and RS485 connections, with MODBUS RTU protocol for communication.

System Power Requirements:
Operates on an external power supply of 10 to 30 Vdc, with reverse polarity protection. It supports external rechargeable batteries and has specified current drain values for different operational modes.

Software & Firmware:
Includes an onboard web server, supports data acquisition intervals from 1 second to 1 week, and allows data/alarms to be sent via FTP, email, or SMS. Data can be downloaded in .csv format.

Environmental Conditions:
Operates within a temperature range of -30 to 70°C and can be stored between -40 to 85°C. It is designed for use at altitudes up to 3000 meters.
