ADAS STB420 总线通讯板卡 英文介绍
ADAS STB420 is a communication board used in industrial fieldbus systems, focusing on solving data link stability and signal adaptation issues between control systems and field devices.
10 in the middle
This board supports mainstream bus protocols such as Profibus DP or Modbus RTU.
The communication port adopts differential signal transmission method and has strong resistance to common mode interference.
The board has a built-in terminal resistor, which can be enabled or not through jumper selection based on the network location.
Supports multiple communication speed levels between 9.6 kbps and 12 Mbps.
Each communication cycle can handle up to 64 bytes of input and 64 bytes of output data.
The power supply adopts reverse connection protection and overvoltage protection design to reduce the risk of damage caused by wiring errors.
When the bus fails, it can automatically switch to a safe output state to prevent misoperation.
The station address and communication parameters can be configured through software without the need for a hardware dip switch.
The shell adopts a metal shielding layer to further suppress the impact of electromagnetic interference on communication.
Shared backplane bus with other ADAS STB series cards, plug and play.
ending
Overall, ADAS STB420 focuses on the physical layer stability and protocol compatibility of bus communication, making it suitable for distributed control scenarios that require high communication quality.
