1746-NI16I Analog Input Module

1746-NI16I Analog Input Module

Details of the module

The 1746-NI16I is an Analog Input Module, with 16-bit resolution and 16 input channels. This module falls into a 

Voltage Category of -20 to 20 mA. Its backplane current at 5 Volts is 125 mA, while 24 Volts results in 75 mA. Its 

backplane power consumption is 2.425 Watts maximum (0.625 Watts at 5 Volts DC and 1.8 Watts at 24 Volts DC). 

The common mode voltage range of this module is +/-10.25 Volts relative to the analog common terminal.
This unit has a relative humidity of 5% to 95% without condensation. Its operating temperature range is -25 to 60 

degrees Celsius (-13 to 140 degrees Fahrenheit) while its nonoperating temperature lies between -40 and 85 degrees 

Celsius (-40 and 185 degrees Fahrenheit). Its Input impedance is 249; its maximum voltage input is ±8 Volts between 

analog common and any input terminal, and the maximum current input is ±30 mA. The thermal dissipation of this 

module is 2.43 Watts, and the AIFM Connector of this module is 25-pin D-shell. When installing modules in the chassis, 

it is not necessary to remove the terminal blocks from the module. However, if the terminal block is removed, use the 

label located next to the terminal block to identify the location and type of module.

Product Applications

Oil and Chemical Industry: Commonly used in the automatic water injection systems of oil fields, pressure monitoring and 

flow control. Its 16-channel high-density design is highly suitable for handling a large number of sensor feedbacks 

within chemical plants.
Water Treatment and Environmental Protection: Used in sewage treatment or water supply systems to monitor key 

process parameters such as liquid level, temperature, pressure and pH value.
Heavy Industry and Energy: Applied in SCADA (Data Acquisition and Monitoring) systems of cement, power and 

mining industries, for real-time reading of the operating status of remote equipment.
Food and Beverage Processing: Used in filling lines and sterilization processes for precise temperature and flow 

control, supporting PID closed-loop regulation.

Key technical features
High-density acquisition: A single module supports 16 input channels, effectively reducing the space occupied by the 

PLC rack and lowering the system cost.
Industrial-grade anti-interference: Designed for harsh factory environments with electromagnetic interference, vibrations, 

and humidity, it has extremely strong signal stability.
Flexible configuration: Each channel can be independently configured, supporting standard current signals such as 

4-20mA and 0-20mA.
Precise conversion: With 16-bit resolution, it can provide high-precision data conversion, meeting the requirements of 

precise production.
