Product Description

I. Overview

KJ4002X1 - BA1 is an important analog input/output hybrid module in Emerson's DeltaV Distributed Control System (DCS). It integrates the functions of analog signal acquisition and analog signal output, capable of simultaneously monitoring on-site analog parameters and performing analog control on executive devices. It is a key component for the DeltaV system to realize complex industrial process control.

In the field of industrial automation, many production processes require both real-time acquisition of analog parameters such as temperature, pressure, and flow, and continuous analog regulation of devices like control valves and frequency converters. The KJ4002X1 - BA1 module precisely meets this hybrid control demand. It can efficiently work in collaboration with the DeltaV control system, providing strong support for the accurate regulation of production processes. For example, in the boiler control of a thermal power plant, this module, on one hand, collects analog signals such as boiler drum water level and steam pressure, and transmits them to the DeltaV control system for operational analysis; on the other hand, it receives regulation commands from the control system, converts them into corresponding analog signals to control the opening of the feedwater control valve and the air supply volume, thereby ensuring the stable operation of the boiler.

II. Technical Parameters

(1) Electrical Parameters
Power supply voltage: 24V DC power supply is adopted, which matches the power supply standards of most automation equipment in industrial sites, facilitating the unified configuration of the system power supply. The module has strong power adaptability, and can maintain a stable working state when the voltage fluctuates within the range of 24V DC±10%, ensuring the accuracy of signal acquisition and output.

Input signal parameters: It supports 4 - 20mA DC current signal input, which is the most commonly used analog signal type in industry. It can be directly connected to various transmitters for collecting physical quantities such as temperature, pressure, and flow. The input impedance is 250Ω, which meets the design requirements of standard analog input circuits and ensures stability during signal transmission.

Output signal parameters: It provides 4 - 20mA DC current signal output, with an output load capacity of 0 - 750Ω, which can directly drive executive devices such as control valves and electro-pneumatic converters. The output accuracy is high with a small error range, ensuring that executive devices can accurately respond to control commands.

Power consumption: The power consumption during normal operation is low, usually not exceeding 6W, which will not impose an excessive burden on the system power supply. At the same time, it reduces the heat generation of the module, which is beneficial to prolonging its service life.

(2) Performance Parameters
Channel configuration: It includes 4 analog input channels and 2 analog output channels. This combined design of input and output channels is suitable for industrial control scenarios that require simultaneous monitoring of a small number of parameters and regulation of a small number of devices. It not only meets the control needs but also avoids resource waste.

Accuracy class: The measurement accuracy of the analog input channel is ±0.1% of full scale, and the output accuracy of the analog output channel is ±0.1% of full scale. The high-precision performance ensures the accuracy of signal acquisition and control output, providing a reliable guarantee for the refined control of the production process.

Response time: The response time of the analog input channel is less than 50ms, which can quickly capture changes in on-site parameters; the response time of the analog output channel is less than 10ms, which can timely transmit control commands to executive devices, ensuring the real-time performance of control.

Stability: It has good long-term stability. When the ambient temperature and power supply voltage fluctuate normally, the drift of input and output signals is extremely small, and it can maintain high accuracy for a long time, reducing the number of system calibrations and maintenance workload.

(3) Physical and Environmental Parameters
Protection level: The shell protection level is IP20, which is suitable for the environment installed inside the control cabinet. It can prevent large solid foreign objects from entering the module and protect circuit components from damage. The inside of the module adopts effective electromagnetic shielding measures, which can resist electromagnetic interference in the industrial environment and ensure stable signal transmission.

Working environment conditions: The working temperature range is -40°C to 70°C, which can work normally in extreme temperature environments such as cold northern winters and hot southern summers; the relative humidity is 10% - 95% (no condensation), which can adapt to humid industrial environments such as paper mills and printing and dyeing factories. In addition, the module can withstand certain vibration and impact. It can still maintain a normal working state under the conditions of vibration frequency 10 - 500Hz, acceleration 5g, and impact acceleration 15g.

Size and weight: The external dimensions of the module are 115mm in length × 90mm in width × 35mm in height, and the weight is about 280g. It has a compact structure and small size, occupies little space in the control cabinet, and is convenient for installation and layout.

Installation method: It adopts 35mm standard DIN rail installation. The installation process is simple and convenient, without special installation tools. It can be fixed by simply clamping the module into the rail, which improves the efficiency of system installation.

III. Functional Features

(1) Hybrid Control, Efficient Collaboration
Integration of input and output: The functions of analog input and analog output are integrated into one module, reducing the number of modules in the system, simplifying the system structure and wiring, and reducing the space occupation rate of the control cabinet. At the same time, the signal transmission path between input and output channels is short, and the response speed is fast, which improves the control efficiency of the entire control loop.

In-depth collaboration with DeltaV system: As a dedicated module for the DeltaV system, it can achieve seamless connection with controllers, configuration software, etc. in the system. During the operation of the system, the module can quickly exchange data with the controller, ensuring that the collected analog signals are transmitted to the controller in a timely manner, and the control commands issued by the controller can be quickly executed by the module, realizing efficient collaboration of input, operation, and output.

(2) High-Precision Signal Processing
Accurate signal acquisition: The analog input channel adopts a high-precision A/D conversion chip and advanced signal conditioning circuit, which can accurately convert and process the input 4 - 20mA signal, effectively filter out noise and interference in the signal, and ensure that the collected signal truly reflects the actual situation of on-site physical quantities. For example, in the temperature acquisition process of a chemical reaction kettle, it can accurately capture the subtle changes in temperature, providing an accurate data basis for the control of the reaction process.

Precise control output: The analog output channel adopts a high-performance D/A conversion circuit, which can accurately convert the digital control signal from the controller into a 4 - 20mA analog current signal. The output signal has good linearity and stability, and can maintain output accuracy even when the load changes, ensuring that executive devices can act accurately according to control requirements.

(3) Reliable Operation Guarantee
Comprehensive self-diagnosis function: The module has comprehensive self-diagnosis capability, which can monitor its own working status in real time, such as power failure, channel failure, A/D or D/A conversion failure, etc. When a fault is detected, it will timely upload the fault information to the DeltaV control system, and send an alarm signal through the system to remind operators to handle it in time, improving the maintainability of the system.

Overcurrent protection: The analog output channel is equipped with an overcurrent protection circuit. When the output current exceeds the rated value, the protection circuit will act quickly to limit the output current, preventing the module and executive devices from being damaged due to overcurrent. After the fault is eliminated, the output function can be automatically restored, ensuring the safe operation of the system.
