I. Product Overview

Rockwell Automation 1746-NIO4I is a 4-channel analog input/output combination module in the SLC 500 series. It integrates the functions of analog signal acquisition and control output, playing an important role in industrial automation control systems. It is suitable for scenarios that require simultaneous monitoring and control of a small number of analog signals, such as small chemical reactors, precision constant temperature equipment, and small water treatment systems. By collecting on-site analog signals such as temperature, pressure, and liquid level, and outputting corresponding control signals according to system logic, it realizes precise regulation of equipment and provides strong support for the stable operation of the system.

II. Technical Parameters

Input parameters:
Number of input channels: Up to 4 (configurable).
Input signal types: Current signals (4-20mA, 0-20mA, etc.), voltage signals (0-10V DC, ±10V DC, etc.).
Input impedance: Usually 100kΩ for voltage input, 250Ω for current input.
A/D conversion resolution: 12 bits.
Input accuracy: ±0.1% full scale (typical value).

Output parameters:
Number of output channels: Up to 4 (configurable).
Output signal types: Current signals (4-20mA, 0-20mA, etc.), voltage signals (0-10V DC, ±10V DC, etc.).
Output load capacity: Minimum load of 5kΩ for voltage output, maximum load of 500Ω for current output.
D/A conversion resolution: 12 bits.
Output accuracy: ±0.1% full scale (typical value).

Electrical parameters:
Backplane current: Approximately 100mA at 5V DC, approximately 50mA at 24V DC.
Isolation voltage: There is certain isolation between channels and between channels and the backplane, usually 250V AC.

Physical parameters:
Dimensions: Approximately 160mm in length, 100mm in width, 150mm in height (compatible with other modules in the SLC 500 series).
Weight: Approximately 0.5kg.

Environmental parameters:
Operating temperature: 0°C-60°C.
Relative humidity: 5%-95% (non-condensing).
Anti-vibration performance: 10-55Hz, amplitude 0.38mm.
Impact resistance: Peak acceleration 15g (duration 11ms).

III. Functional Features

Integrated input and output design: It contains 4 channels, which can be flexibly configured as analog input or output channels. It can meet the needs of collecting and controlling a small number of analog signals at the same time without needing to be equipped with separate input and output modules. This simplifies the system structure, saves rack space, and reduces equipment costs.

Support for multiple signal types: Input channels are compatible with various current signals (such as 4-20mA, 0-20mA, etc.) and voltage signals (such as 0-10V DC, ±10V DC, etc.). Output channels can provide corresponding current or voltage control signals, which can adapt to various sensors, transmitters, and actuators, enhancing the versatility of the module in different application scenarios.

High-precision conversion performance: It adopts 12-bit A/D and D/A conversion technologies to ensure the accuracy of analog signal acquisition and output, reduce errors in the signal conversion process, meet the precision requirements of small and medium-sized control systems, and ensure the accuracy of equipment control.

Flexible channel configuration: The input/output type and range of each channel can be independently set through programming. Users can flexibly adjust according to actual needs to adapt to the signal characteristics of different on-site equipment, improving the flexibility of the module.

Reliable anti-interference ability: It has certain electrical isolation and filtering functions, which can effectively resist electromagnetic interference, voltage fluctuations, etc. in industrial sites, ensure the stability of signal acquisition and the reliability of output control, and reduce the impact of external interference on the system.

Convenient status monitoring: Equipped with status indicators, it can intuitively display the power status, communication status of the module and the working status of each channel. It is convenient for operators to quickly judge whether the module is running normally, and can timely detect and troubleshoot when a fault occurs.

Good system compatibility: As a standard module of the SLC 500 series, it has good compatibility with the rack, power module, and CPU module of the series. It can be seamlessly integrated into the system to ensure smooth data transmission and stable operation of the entire system.
