PMKHRMPBA2000A Bus Redundancy Cable

ABB PMKHRMPBA2000A Bus Redundancy Cable

Basic Information

Product Model: PMKHRMPBA2000A.

Product name: Bus Redundancy Cable, which indicates that it is a cable for bus redundancy (Bus Redundancy), mainly used in industrial automation systems and other fields, the purpose of which is to provide an alternate communication path when the main communication bus fails to ensure the reliability of system communication.

Functional features

Redundancy function safeguards communication

Backup communication path establishment: the core function of this cable is to provide redundant backup in the bus communication of industrial automation system. Under normal circumstances, the main bus undertakes the main communication task, but when the main bus interrupts the communication due to line damage, equipment failure or other disturbing factors, this redundant cable can quickly switch over and establish a backup communication path, so that the data transmission within the system and the communication between the devices can continue. For example, in a distributed control system, the controller communicates with a number of remote I/O devices via a bus. When the main bus fails, the redundant cable ensures that the controller can still receive data sent by the I/O devices and maintain normal operation of the system.

Seamless switching mechanism (if any): Automatic or manual seamless switching may be available. The automatic switchover mechanism can automatically enable the redundant cable to communicate the moment a main bus failure is detected, with minimal disruption to system operation, even making the communication interruption virtually unnoticeable to the system user. Manual switchover provides maintenance personnel with the option of controlling the switchover when necessary, allowing them to select the appropriate switchover timing based on specific fault conditions and maintenance requirements.

Signalling characteristics

High-speed and stable data transmission: In order to meet the requirements of industrial automation systems for data transmission speed and stability, this cable can support high-speed data transmission. It can transmit various types of bus signals, such as digital signals, analogue signals or signals based on specific communication protocols (e.g. Profibus, Ethernet/IP, etc.), and ensures the accuracy and integrity of the signals during transmission. For example, when transmitting large amounts of real-time production data (e.g. temperature, pressure, flow, etc. collected by sensors), the cable is able to transmit the data quickly between devices with a high bandwidth and a low BER.

Anti-interference performance: In industrial environments, there are a variety of electromagnetic interference sources, such as large motors, frequency converters and other equipment generated electromagnetic interference. In order to ensure that the signal transmission is not interfered, the cable may adopt shielding technology, such as metal braid shielding or aluminium foil shielding, which effectively shields the external electromagnetic interference and also prevents the internal signal from radiating outwards to interfere with other equipment. In addition, the stranded construction of the cable (in case of twisted pair or multi-core stranded wire) also helps to reduce electromagnetic induction interference and improve signal quality.

Physical Characteristics and Adaptability

Suitable physical size and flexibility: with reasonable physical size, including wire diameter, length, etc.. The wire diameter size is determined according to the size of the current that can withstand and the requirements of signal transmission, both to ensure sufficient conductive capacity, but not too bulky. Cable flexibility is good, convenient in the control cabinet or industrial site for wiring, can be bent and laid according to different equipment layout and installation path, easy to install and maintain.

Durability and environmental adaptability: Shell materials and internal insulation materials usually have good mechanical properties and chemical stability, and can adapt to harsh industrial environments. It can withstand high temperature, humidity, dust, corrosive gases and other unfavourable factors, and has a certain degree of resistance to abrasion and tensile ability to extend the service life of the cable. For example, in harsh environments such as chemical plants or offshore oil platforms, the cable can work stably for a long time and reduce failures caused by environmental factors.

Application Areas

Industrial automation control system: widely used in automated production processes in chemical, petroleum, natural gas, electric power, metallurgy, pharmaceutical and other industries. In these systems, the reliability of bus communication is crucial, and any interruption in communication may lead to production standstill or equipment damage. For example, in the petrochemical production process, redundant cables can ensure stable communication between the controller and various field devices (e.g., sensors, actuators), real-time monitoring and control of the production process, such as temperature and pressure control of the reactor, and material transport control.

Smart factory construction: it is an important part of building smart factory communication network. In the smart factory, a large number of devices are interconnected through the bus, such as intelligent robots, automated production line equipment, intelligent storage equipment, etc.. The use of redundant cables can improve the reliability of the entire factory communication system, achieve remote monitoring of equipment, fault diagnosis and predictive maintenance and other functions, to protect the intelligent production and efficient operation of the factory.

Transportation system automation: It is also applied in the automation system of railway, highway, port and other transportation fields. For example, in port automation container terminals, it can be used to ensure communication redundancy between crane control systems, vehicle dispatching systems, cargo monitoring systems, etc., to improve the efficiency and safety of port operations, and to prevent operation interruptions or accidents caused by communication failures.
