DSQC249B Redundant link module

DSQC249B Redundant link module
ABB DSQC249B is a PROFIBUS DP protocol fieldbus redundant link module. The module can realize the mutual conversion of single bus and redundant dual bus. It can convert single cable bus into redundant Profibus DP bus and redundant Profibus DP bus into single cable bus, and supports many common rates of Profibus DP bus.
In addition, ABB 3HAL025338-006/08A module also has a variety of features, such as optocoupler isolation, interference reduction performance, industrial design, IP30 protection class, corrugated aluminum reinforced housing, 35mmDIN rail mounting, DC(9-36)V wide power input, relay alarm output, etc. Dual power supply redundancy and isolation protection.
ABB DSQC249B is a PROFIBUS DP protocol fieldbus redundant link module. Its main functions are as follows:
Bus conversion function: The module can realize the mutual conversion of single bus and redundant double bus. This means that it can convert a single cable bus into a redundant Profibus DP bus, and it can also convert a redundant Profibus DP bus into a single cable bus.
Rate support: The module supports a variety of common rates of the Profibus DP bus, and can be set by the dip switch or select the rate adaptive mode.
Performance and stability: The module has optocoupler isolation, reduce interference and other performance features, which helps to improve the stability and reliability of the system. In addition, its industrial design, IP30 protection rating, and multiple power and alarm functions further enhance its performance in practical applications.
