DSBC 173 57310001-KH ABB Bus Repeater Slave Module

The ABB DSBC 173 57310001-KH, also cataloged as the DSBC 173 Bus Repeater Slave, operates as a dedicated hardware component for localized control logic execution within Advant OCS networks. Configured for signal amplification and electrical isolation across extended bus topologies, the assembly reconstructs degraded transmission frames to provide direct physical/electrical execution of real-time communication protocols.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks and I/O Density Scaling

The internal signal-conditioning circuitry of the ABB DSBC 173 57310001-KH is calibrated to match strict backplane bus communication velocity parameters. When bridging field segments to higher-level industrial topologies, such as Profinet or EtherNet/IP deterministic networks, the module handles cross-network data packets without increasing propagation latencies. The 10-channel layout isolates electrical noise vectors during periods of high I/O density scaling, keeping data frame transitions accurate and maintaining local node operation within the boundaries of host controller firmware flash compatibility requirements.

Frequently Asked Questions

Q: Is hot-swapping or live extraction of the M8 connector plugs supported while the module is powered?

A: No. The DSBC 173 does not feature active live-insertion isolation circuitry. Removing or re-inserting the communication interfaces while the 24 VDC supply or bus segments are energized can cause electrical transients, causing immediate data frame corruption or permanent physical trace failure on the communication paths.

Q: How is an internal channel signal degradation or transmission fault diagnosed?

A: Diagnostic states must be verified through the central host controller register map. If a bus link drops or registers CRC errors, check the physical 24 VDC input tolerances and confirm that the overall cable length across the M8 connectors does not violate protocol distance specifications.

Field Installation Guidelines

1. ESD Grounding Requirements: Technical field personnel must use a properly calibrated and grounded electrostatic discharge (ESD) wrist strap prior to opening the protective packaging or handling the internal circuit boards to prevent dielectric micro-circuit damage.
2. Mechanical Mounting and Fastening: Mount the 0.43 kg housing securely inside the control enclosure. When mating the M8 x 0.8 mm pitch connectors, torque the connections to factory specification limits to avoid loose mechanical contacts and ensure proper environmental sealing.
3. Control Cable Routing Isolation: Route all incoming DeviceNet and CANopen communication lines inside separate low-voltage wireways. Keep a physical separation distance of at least 100 mm from high-voltage AC conductors and motor drive cabling to protect against electromagnetic interference.
4. Environmental Exposure Limits: Install the module inside an IP 54 or better enclosure that eliminates ambient moisture condensation, airborne conductive dust, and corrosive vapors to prevent tracking short-circuits.
