ABB H&B Contronic SS 21 Module SS 21 H&B Contronic

ABB H&B Contronic SS 21 Module SS 21 H&B Contronic

Basic information

Model number and logo: Model number is SS 21, with ‘SS 21’ and ‘ABB H&B Contronic’ printed prominently on the surface of the module, which is convenient for quick identification and maintenance in the equipment.

Appearance and size: usually adopts the standard industrial module shape design, rectangular shape, the shell is generally made of metal or high-strength engineering plastics, with good electromagnetic shielding performance and mechanical protection, can adapt to the more severe industrial environment. Compact size, easy to install and integrate in the control cabinet, usually can be mounted on the standard DIN rail.

Technical Parameters

Power input: generally 24V DC DC power supply, the working voltage range is usually between 20V DC and 30V DC, with a certain degree of tolerance for voltage fluctuations to ensure that in the industrial field power supply instability can still work normally.

Input and output channels: The digital input channels can receive switching signals from external devices such as sensors, switches, etc., such as 0V or 24V indicating the on/off state. The digital output channels can output corresponding switching signals for controlling actuators such as relays and contactors. Some models may also have analogue input and output channels, which can receive and output standard analogue signals such as 0-10V, 4-20mA, etc. to achieve measurement and control of analogue quantities.

Communication interface: Supporting a variety of common industrial communication protocols, such as Profibus, Modbus, CANopen, etc., it can conveniently communicate and interact with other ABB equipment and third-party industrial automation equipment to achieve system integration and cooperative work. The communication rate is generally high, which can meet the data transmission needs of industrial sites with high real-time requirements.

Functional features

Signal processing function: it can collect, filter and amplify the input digital and analogue signals to effectively improve the quality and accuracy of the signals, reduce the impact of external interference on the signals, and ensure that the system can obtain reliable measurement data and control commands.

Control Logic Functions: Rich control logic functions are integrated internally, which can be flexibly set through programming or configuration software to realise various complex control strategies, such as logic operation, timing control, counting control, etc., to meet the control requirements in different industrial production processes.

Diagnostic and Alarm Function: With comprehensive self-diagnostic function, it can monitor its own working status in real time, including power supply voltage, working temperature, input/output channel status, communication connection status and so on. Once the abnormal situation is detected, it will immediately send alarm information to the monitoring system through the communication interface, and carry out intuitive alarm prompts locally through the indicator or display, which is convenient for the maintenance personnel to locate and solve the problem quickly.

Application Fields

Manufacturing automated production line: In automated production lines of automobile manufacturing, machining, electronic equipment production and other industries, it is widely used in logic control, sequence control and motion control of equipment, such as control of robots, start-stop control of conveyor lines, and coordination of movements of automated assembly equipment, etc., and it can effectively improve production efficiency and product quality.

Process industrial control system: in the chemical, pharmaceutical, food and beverage, sewage treatment and other process industries, used in the production process of temperature, pressure, flow, liquid level and other physical quantities of the measurement and control, to achieve the automation of the production process monitoring and optimisation of the adjustment, to ensure the safe and stable operation of the production process and the consistency of product quality.

Energy management and monitoring system: in the power, heat, gas and other energy supply and management industry, it can be used for monitoring and control of energy production equipment, transmission equipment, metering equipment, etc., to achieve optimal distribution and management of energy, improve energy efficiency, reduce energy loss, and at the same time, timely alarms and treatment of energy system failures to ensure the reliability of energy supply.
