Description

ABB CI615K01 3BSE000756R1

Functional Features: As a bus expansion module, it is primarily used to expand the I/O bus in industrial automation systems, enabling connection and communication between different devices. This allows the system to connect more input/output modules, thereby increasing the number of control points and functional scalability of the system.


Composition Structure: The bus expansion module includes 1 CI615 IOB_A bus coupler for the I/O expansion unit and 1 TC610 bus terminator for the I/O expansion bus.


Technical Parameters: It typically operates at 24VDC, offering high reliability and stability. It can function normally in an ambient temperature range of -20°C to +60°C, supports multiple communication protocols, and is compatible with devices such as ABB's Advant controllers.


Application Scenarios: Widely used in various industrial automation control systems, such as chemical, power, metallurgy, and papermaking industries. In the production process control of these industries, it can expand the system's I/O capabilities to meet the monitoring and control requirements for a large number of devices. For example, in papermaking production lines, it can connect multiple measuring instruments and control devices to achieve precise control and monitoring of various parameters during the papermaking process.


Working Principles:
Communication Principle: As a bus expansion module, it may support multiple communication protocols, such as common industrial Ethernet protocols, to interact data with other devices through specific communication protocols. Taking the MODBUS TCP protocol as an example, it inserts MODBUS application data units into TCP messages to achieve data transmission. It parses received messages to extract valid data and executes corresponding operations based on function codes, such as reading device data or writing data to devices. At the same time, it encapsulates data from local devices according to protocol formats and sends them to other devices, thus enabling communication between devices.


Data Processing Principle: Received data may undergo processing such as caching, decoding, and verification. For digital signals, logical judgment and processing may be performed directly; for analog signals, they need to be converted into digital signals through analog-to-digital conversion circuits before processing. Processed data may be stored in internal memory for reading by other modules or devices, or further analyzed and processed according to preset rules (e.g., data calculation, status judgment), followed by corresponding operations based on results, such as controlling relay outputs or sending alarm signals.


Signal Processing Principle: If the module has input signal interfaces, it receives signals from sensors or other devices—for example, digital input signals for receiving binary information and analog input signals for receiving continuous signals (e.g., readings from temperature and pressure sensors). For these input signals, the module performs processing such as sampling, quantization, and encoding to convert them into digital signals that can be transmitted and processed on the internal bus. If the module has output signal interfaces, it generates corresponding output signals based on internal control logic and processing results—for example, digital output signals for controlling the on/off status of external devices and analog output signals for adjusting continuous variables of external devices (e.g., controlling motor speed or valve opening).
