Product Description

I. Product Overview

1746SC - INO4I is a high-performance analog output module launched by Allen - Bradley, a brand under Rockwell Automation. It is specifically designed for the SLC 500 series of programmable logic controller (PLC) systems. In the process of industrial automation, it plays an extremely important role. Its main responsibility is to accurately convert the digital signals inside the PLC into analog current signals for output, thereby achieving precise control of various actuators and ensuring the stability and efficiency of industrial production processes. From precision machinery manufacturing to complex chemical processes, from efficient warehousing and logistics to strict food and beverage production, this module ensures the accurate operation of equipment in all links with its excellent performance and is an indispensable key component in industrial automation control systems.

II. Functional Features

Multi-channel independent output: It has 4 independent analog output channels, each of which can work independently and drive 4 different actuators at the same time, meeting the diverse control needs in complex industrial control systems. For example, in an automated production line, it can control regulating valves, frequency converters and other equipment at different stations respectively, realizing refined control of the production process and greatly improving the control flexibility and efficiency of the system.

Wide range of output signals: It supports a variety of common output signal ranges, including 0 - 20mA, 0 - 21mA, and 4 - 20mA, and can perfectly adapt to various industrial on - site equipment. Whether driving small electric valves or large industrial pumps, it can provide stable and appropriate current signals to ensure the normal operation of the equipment, effectively reducing equipment failures or performance degradation caused by signal mismatch.

High resolution and high precision: It has a 16 - bit resolution, which means it can output extremely delicate analog signals. Corresponding to each digital quantity change, the change of the output signal is as low as 366nA (current) or 320μV (voltage), thus achieving high - precision control. In industrial scenarios with extremely high requirements for control precision, such as precision etching processes in semiconductor manufacturing, it can accurately control the working parameters of etching equipment to ensure the consistency and stability of product quality. Its output accuracy can reach 0.10% - 0.35%, effectively reducing control errors and ensuring that the production process is strictly carried out in accordance with preset standards.

Strong isolation performance: The module adopts advanced electrical isolation technology internally, and the isolation voltage between channels and between on - site wiring and the backplane is as high as 750V DC. This strong isolation performance can effectively block electrical interference between different circuits, prevent signal distortion or misoperation caused by interference, and avoid the spread of faults between different modules, greatly improving the reliability and stability of the system. Even in industrial sites with complex electromagnetic environments, it can run stably.

Automatic calibration and safety protection: It has an automatic calibration function, which can regularly self - calibrate the output signal to ensure the accuracy and stability of the output during long - term operation and reduce the workload and cost of manual calibration. In addition, it also has a built - in perfect safety protection mechanism. For example, overcurrent protection can prevent damage to the module due to load short circuit or excessive current; overvoltage protection can cope with abnormal high - voltage input to protect internal precision components; in case of failure, the output safety state can be set through programming to avoid production accidents caused by module failure, comprehensively ensuring the safe operation of the system.

Flexible configuration and programming: It supports software configuration. Users can flexibly set parameters such as the output range and output limit of each channel through programming software according to actual needs, so as to quickly and conveniently adapt to different industrial control scenarios. At the same time, during the operation of the system, the configuration can also be adjusted in real time according to the actual production situation, which enhances the scalability and adaptability of the system and provides strong support for the optimization and upgrading of industrial automation production.

Good environmental adaptability: Designed in accordance with industrial - grade standards, it can work stably in the temperature range of 0℃ - 60℃, is not affected by the relative humidity of 5% - 95% (non - condensing), and has certain vibration and impact resistance. Whether in high - temperature steel smelting workshops, humid food processing environments, or mining sites with strong vibration, 1746SC - INO4I can run reliably, ensuring the continuity and stability of industrial production.
