ABB DSBC173 Bus Repeater Slave Module
The ABB DSBC173 57310001-KH, also cataloged as the DSBC173 Bus Repeater Module, operates as a dedicated hardware component for MasterBus 300 (MB300) signal amplification and line driver interface within Advant OCS and MasterPiece 200/200/1 control networks. Serving as a dedicated slave repeater, this module restores physical layer signal amplitudes, suppresses line attenuation, and conditions differential data frames across extended bus segments.

Backplane Bus & Deterministic Communications
Maintaining deterministic communication speeds across the MB300 fieldbus requires strict signal timing and propagation delay management. The DSBC173 interfaces with the backplane bus to re-clock incoming serial data streams, removing jitter accumulated across long transmission distances. The module maintains firmware flash compatibility with host node controllers, enabling stable frame passing without introducing routing latencies or buffer overruns into the deterministic network loops.
Frequently Asked Questions
Q: What physical network topology requires the installation of a DSBC173 slave repeater?
A: The module is required when extending MasterBus 300 coax or twisted-pair trunk line lengths beyond standard distance limits or when bridging multiple node racks across noisy industrial environments.
Q: Does replacing a DSBC173 module require re-flashing the host system controller firmware?
A: No, the DSBC173 functions at the physical communication layer, maintaining hardware compatibility across standard MB300 firmware flash revisions without necessitating controller re-configuration.
Field Installation Guidelines
- De-energize the host rack power supply before inserting or seating the DSBC173 module into the card slot.
- Ensure coaxial or twisted-pair network cables connect using proper BNC or terminal block connectors with correct line termination impedance.
- Clamp cable shielding directly to the cabinet functional earth bus using short, low-impedance copper jumpers to divert high-frequency noise.
- Verify minimum ventilation clearances above and below the module mounting position to maintain passive convection cooling.
