DSBC176 3BSE019216R1

MXB bus signal regeneration and long-distance expansion
Shaping, amplifying, and synchronously reconstructing MXB bus signals between racks, significantly extending the communication distance between the main control and remote I/O racks, solving the problem of signal attenuation and distortion in long cables, and supporting multi rack distributed I/O networking.
Bus node expansion, expanding the number of I/O racks
Breaking through the upper limit of single segment MXB bus mounting racks, coupled with the backplane DSBB series to achieve cascading expansion of multiple I/O racks, suitable for large-scale chemical and power plant multi-point control scenarios.
Dual redundant bus isolation anti-interference
Built in electrical isolation and EMC filtering circuit to suppress RF interference from frequency converters and high-voltage equipment, eliminate ground loops, and ensure the accuracy of AI/AO analog signals; Support A/B dual bus undisturbed automatic switching.
Real time bus diagnosis and fault reporting
Continuously inspect bus disconnection, short circuit, signal distortion, and communication timeout; Panel LED intuitive fault indicator light, fault code uploaded to AC410/AC450 main control, quickly locate communication faults.
Timing synchronization calibration
Unified bus scanning clock for multiple expansion racks to ensure consistent timing of I/O data acquisition across the entire system and avoid timing confusion in closed-loop control logic.
Hot swappable compatible design
The cabinet can be plugged and replaced separately when it is live, without the need for shutdown or program modification, and without interrupting the entire production control circuit.
All series of Advant cards are compatible
Perfectly matched with DSBB110A, DSBB175 backplane, DSBC172 bus relay, DSAO120A analog output, and DSAI/DSDI digital input/output modules across the entire series.
