PM904F ABB AC 900F cpu module

In terms of functional enhancement:
Compared to the standard version PM902F, PM904F has more powerful functions. It extends the functionality of PM902F, providing stronger processing capabilities and more functional support for complex automation control tasks.
Supports up to four Profibus or CAN communication interfaces, facilitating communication with other devices and systems, enabling a wider range of device connections and system integration. The standard version PM902F and the simplified version PM901F support a maximum of two communication interfaces.
Having more application memory can meet more complex control program and data storage requirements. For example, in large-scale industrial automation projects that require processing large amounts of real-time data and complex control logic, the PM904F’s large memory advantage can well meet these requirements.
In terms of hardware parameters:
Relatively compact in size, easy to install in various industrial control cabinets and equipment. The specific size information is usually within a certain range for length, width, and height (the specific size may vary slightly due to product batch and detailed specifications). This compact design does not occupy too much installation space and is easy to integrate into existing control systems.
The light weight brings convenience to the transportation, installation, and maintenance of the equipment. In some situations where equipment weight is required, such as high-altitude installation or limited space, the lightweight characteristics of PM904F make it more suitable for use.
In terms of communication capability:
Equipped with multiple Ethernet interfaces, it can achieve high-speed data transmission and network communication. Some of the Ethernet interfaces are used for communication with protocols such as Modbus TCP and IEC60870-5-104 for remote control, providing support for remote monitoring and management of the system.
In addition to Ethernet communication, it also has two serial interfaces that support RS-232 or RS-485 communication protocols, with communication rates ranging from 600bps to 38400bps, meeting the communication needs of different devices and scenarios. For example, when communicating with some outdated devices, the compatibility of serial interfaces becomes particularly important.
In terms of environmental adaptability:
Compliant with G3 standards, capable of stable operation in harsh industrial environments, with high anti-interference ability and reliability. PM904F can maintain stable performance under harsh environmental conditions such as high temperature, high humidity, and strong electromagnetic interference, ensuring the normal operation of industrial production processes.
The working temperature range is wide, and there is no need for forced cooling when the ambient temperature is between -20 ℃ and+70 ℃. It can also maintain good performance within the storage temperature range of -40 ℃ to+85 ℃, and is suitable for various industrial environments.
In terms of system scalability:
As part of the AC 900F controller, fieldbus modules and I/O modules can be added according to actual application needs to facilitate system expansion and upgrades. For example, in the industrial production process, with the expansion of production scale and the increase of control requirements, it is convenient to add corresponding modules to meet the expansion needs of the system.
Supporting redundant configuration and optional redundancy functions improves the availability and reliability of the system. In some critical industrial production processes that require extremely high system reliability, redundant configuration can ensure that the system can still operate normally in the event of a failure, reducing production interruptions and losses caused by system failures.

ABB, the world’s leading power and automation technology group, announced that it will provide a 363 kV high-voltage isolated circuit breaker with an all fiber current transformer for the Shaanxi Fuping Intelligent Substation. This circuit breaker combines three substation functions: isolation, circuit breaking, and current measurement, reducing the substation’s footprint by up to 70%. At the same time, it is also the world’s first isolated circuit breaker equipped with fiber optic current transformers at this high voltage level.

All fiber current transformers will replace traditional current transformers used for measurement and protection in integrated intelligent switches, and create conditions for grid automation. In the northwest region of China, the voltage level of 363 kV is the most common. This application is also the first commercial application of the isolated circuit breaker technology at this voltage level.

As part of the new generation intelligent substation project planned by State Grid Corporation of China in 2015, Shaanxi Fuping Intelligent Substation will provide electricity for the rapidly developing industrial belt around Fuping County, Shaanxi Province. The project aims to utilize the most advanced technology to enable remote control, protection, automation, monitoring, and analysis of substations, while reducing operating costs, footprint, and environmental impact. At the same time, the new generation of smart substations can make the national power grid more efficient, flexible, and reliable, laying the foundation for China’s increasing integration of renewable energy into the grid. According to data from the National Energy Administration of China, the cumulative installed capacity of renewable energy generation in China exceeded 400 million kilowatts in 2014, accounting for over 30% of the total installed capacity of electricity, continuing to maintain its position as the world’s largest country in terms of renewable energy utilization scale.

ABB has been providing the most advanced technology for China’s power infrastructure construction, supporting a stronger, smarter, and greener power grid through our equipment. This once again demonstrates that leading technology will be the key to ABB’s market leadership position under the ‘new stage’ strategy, “said Yuker, President of ABB’s Power Products Business

As a pioneer in isolated circuit breaker technology, ABB has installed approximately 1800 isolated circuit breakers worldwide. Since 2010, ABB has been operating a test project in Sweden for 420 kV high-voltage isolated circuit breakers equipped with all fiber current transformers, accumulating a wealth of experience in this field. This innovative technology not only integrates three types of substation functions, but also provides digital output of substation and grid automation related data, and is fully integrated into the smart grid based on the latest IEC digital communication standard (IEC 61850-9-2LE).

This technology can replace traditional switchgear and reduce the footprint of air isolation switches in substations by 70%. Not only that, it can also help high-voltage substations reduce several tons of equipment, improve substation safety, reduce installation time, save design, operation, and maintenance costs, and reduce environmental impact.

By the end of 2015, State Grid Corporation of China plans to build a new round of 50 next-generation smart substations and vigorously promote the construction of smart grids. ABB will provide innovative high-voltage isolation circuit breakers equipped with full fiber current transformers, intelligent medium voltage switchgear, and transformer intelligent electronic components (such as innovative self drying respirators) for 13 of the smart substations, helping to create a more efficient and reliable smart grid and achieve the “interconnection of goods, services, and people”.
