ABB 23BE21 Technical Documents

1. Description 

ABB 23BE21 is an advanced industrial control device designed to provide high precision and high reliability of automation-based control solutions for industrial applications. This product uses ABB's expertise in the field of automation to meet complex production requirements in various industrial environments.

2. Hardware Features Housing Design

ABB 23BE21 uses a rugged and durable metal housing, which can well protect against dust, liquids and oils in the air and certain types of mechanical shock. The surface of the housing is also specially treated for corrosion resistance, so it can perfectly adapt to the harsh industrial environment of the chemical and metallurgical industries. Important information such as the device model and interface type are prominently marked on the housing for easy user identification and use.

Interface Type

Power Interface

ABB 23BE21 power interface design is compatible with different types of standard industrial power supplies and has a wide input voltage range, such as [specific voltage range]. In addition, a complete power protection circuit system is built in, with protection functions such as overvoltage, undervoltage, overcurrent, surge, etc., to ensure stable operation of the equipment when the power supply changes and prevent equipment damage due to power supply abnormalities.

Communication interface

ABB 23BE21 is equipped with multiple communication interfaces such as Ethernet interface and RS485 interface. The Ethernet interface supports high-speed Ethernet communication, which can realize fast data transmission between the device and the host computer, PLC or other network devices, and meet the needs of large-capacity data exchange in industrial automation systems. The RS485 interface can connect multiple field devices such as sensors and actuators to achieve long-distance communication, and has strong anti-interference ability, which is of great benefit in building distributed control systems. When designing the onboard input and output interfaces, it is worth considering both analog and digital signals. The device is equipped with a state-of-the-art analog input interface, which can record voltage and current references in the range of 0 to 10 volts and 4 to 20 mA, respectively.

Another important feature is high-precision analog-to-digital conversion, with a recording resolution value of [specific resolution value], which is used to integrate precise analog signal information on site. On the other hand, the analog interface is used as an actuator, and the control signal is used to control valves and inverter equipment. The digital input and output interface allows input and switching signal processing for a variety of purposes. It has sufficient signal transmission capacity - input and output, sufficient signal detection and driving capacity in a short time, allowing relatively complex industrial logic control, and realizing fast detection or output when the signal changes. These functions (including safety circuits) are installed to monitor the ambient temperature and periodic cooling of the products to provide them with services under different temperature flows.

3. The included software is rich in functions

ABB 23BE21 has a wide range of uses from the programming stage to diagnostic monitoring and maintenance use. It supports dedicated programming software and provides two programming methods: graphic and text. The graphical programming interface connects the function blocks with connecting lines through simple drag and drop operations. It is intuitive and easy to understand, and novices can quickly get started and establish control logic. Text programming is more suitable for advanced and experienced people to complete more complex programming tasks. The programming software also has online programming and debugging functions, and users can modify and optimize the program during the operation of the equipment. The various parameters of the equipment can be flexibly configured, including communication parameters, input and output parameters, control algorithm parameters, etc. According to the specific application scenario, users can quickly complete the initialization configuration of the equipment and improve the efficiency of project implementation. The control algorithm has built-in multiple advanced control algorithms, PID control, fuzzy control and adaptive control. The control PID algorithm can accurately control physical quantities such as temperature, pressure, and flow by adjusting the proportion of integral and differential parameters to obtain fast and stable control effects. The fuzzy control algorithm is suitable for nonlinear time-varying complex systems, and can intelligently control the system according to fuzzy rules.

The ABB 23BE21 adaptive control algorithm will automatically adjust its control parameters according to the operating status of the system. The system can improve the adaptability and robustness of the system. Data processing and monitoring Input data processing is real-time and can perform operations such as filtering, amplification, and nonlinearization. The filtering function helps to effectively remove noise from the signal, thereby improving data quality. The amplification operation can enhance weak signals until they reach the state for subsequent processing. Nonlinear sensor signals can be converted into linear signals through linearization.

The powerful data monitoring function equipped with ABB 23BE21 can transmit real-time operating data to the monitoring system through communication interfaces such as SCADA or HMI human-machine interface. Operators can monitor the operating status, input and output data, and faults of the equipment from a distance. At the same time, the equipment itself can display key information through indicator lights or display screens, and promptly convey the equipment status to on-site personnel.

Control accuracy

In analog control, the control accuracy can reach ±0.1%, meeting the high-precision requirements of industrial control. Digital control has high accuracy in signal detection and output, which can ensure the accuracy of industrial logic control. Speed parameters The core processor has fast computing speed and fast single instruction cycle, which can quickly respond to changes in input signals.

The communication interface has high data transmission rate, the Ethernet interface meets the requirements of high-speed data transmission, and RS485 can ensure a stable communication rate. Environmental adaptability The normal operating temperature range of the thermocouple is -20℃～+60℃, and it can work stably under relative humidity conditions (5-95%, no condensation), has good electromagnetic compatibility, and can still maintain reliable operation in complex electromagnetic environments.

Reliability

The mean time between failures (MTBF) is long, that is, greater than unspecified hours/years, thereby reducing the impact of equipment failures on industrial production processes.
