Foxboro DNBT P0971WV Dual-node bus module of I/A series

Foxboro DNBT P0971WV Dual-node bus module of I/A series

DNBT P0971WV is A dual-node bus module of the I/A series under FOXBORO.

It is often used in industrial distributed control systems (DCS) and undertakes the core tasks of signal transmission and data processing. 

The following is its detailed information:

Core technical parameters

Power supply and power consumption:

Compatible with AC 220V/50Hz or DC 24V input voltage, output voltage is DC 5V/1A;

The maximum power consumption is 8.5W. Some channels indicate that its power supply can be compatible with a fluctuation range of 24V DC±10%, 

and is suitable for complex industrial power supply environments.

Performance and storage: It features 16-bit resolution, a response time of less than 100 milliseconds,

and a control accuracy of ±0.1% of the full scale. Equipped with 16MB synchronous dynamic random access memory and 32MB flash memory,

 it can meet the real-time data storage requirements in industrial scenarios.

Environmental adaptability: The operating temperature range covers -40 ℃ to 85℃.

Some parameters indicate the operating temperature from 0℃ to 60℃ and the storage temperature from -20 ℃ to 85℃. It can adapt to harsh industrial environments such as high and low temperatures.

At the same time, the input and output channels and the system have a 1500V isolation performance, which can resist electromagnetic interference and ensure signal stability.

Core functions and advantages

This module is not merely a simple signal transmission component;

it also features basic functions such as logical operations, counting,

and timing, as well as extended functions like numerical operations, analog regulation, and monitoring and recording.

It can achieve multi-variable instrument measurement and help enhance the utilization rate of industrial assets.

It is compatible with the mesh control network structure of the Foxpolo I/A series.

This all-fiber communication design significantly enhances the redundancy of network communication and the ability to resist electromagnetic interference.

Even when installed beside high-voltage cable trays or in outdoor areas prone to lightning strikes, it can avoid equipment damage caused by voltage differences and ground loops.

It is widely applied in scenarios such as DCS monitoring systems in power plants, operation and maintenance management of power projects, and fault handling.

At the same time, it is compatible with distributed control systems in industries like petroleum and chemical engineering.

Through stable data collection and communication, it ensures the continuous operation of industrial production processes.
