DCS Backplane Extension Solution – ABB DSBC173A 3BSE005883R1 | Advant Controller Series
Where This Product Is Used
The ABB DSBC173A (Part No. 3BSE005883R1) Bus Extender Board is a critical backplane extension module deployed in ABB’s Advant Controller (AC 450 / AC 410) Distributed Control System (DCS) platforms. It is found in high-reliability industrial environments where expanding the I/O capacity of an existing controller rack is required without replacing the base unit.
Typical deployment sites include:
- Oil & Gas – Offshore platform process control, pipeline SCADA systems
- Power Generation – Turbine control, boiler management, and grid-tie automation
- Pulp & Paper – Continuous process lines requiring high-channel-count I/O expansion
- Chemical & Petrochemical – Reactor control and safety instrumented systems (SIS)
- Water & Wastewater – Multi-pump station automation and SCADA integration
- Mining & Minerals – Conveyor, crusher, and flotation cell control loops

Application-Specific FAQ
Q: Is the DSBC173A compatible with both AC 450 and AC 410 controllers?
A: Yes. The DSBC173A is designed for the S100 I/O bus architecture shared by both the AC 450 and AC 410 Advant Controller families. Verify your rack revision with ABB documentation before installation.
Q: Can this board be used to extend a rack beyond the standard maximum module count?
A: The DSBC173A extends the physical bus connection between racks. Maximum module count per controller is governed by the CPU’s I/O capacity and ABB’s system configuration rules — consult your AC 450 system manual.
Q: Do you supply the DSBC173A with a test report?
A: Yes. Functional test reports are available for refurbished units. New surplus units include original ABB packaging documentation where available.
Q: What is the difference between DSBC173A and DSBC176?
A: The DSBC173A is a bus extender board that bridges the S100 bus between racks, while the DSBC176 is a bus connection board used for internal rack wiring. Both may be required in a multi-rack expansion.
Q: Can Konmask source other ABB Advant spare parts alongside this order?
A: Yes. We specialize in consolidated BOM sourcing for ABB Advant, Bailey, and 800xA legacy systems. Submit your full parts list for a single-source quotation.
