Description
Product Overview
The ABB 3BSE019958R1 DSBC 176K05 is a connection kit used in ABB S100 I/O bus-extension arrangements. Its purpose is to provide the specified connection components for linking an S100 I/O subrack into an existing control-system configuration. This makes it a system accessory rather than a general-purpose communication module or a standalone controller. The exact contents matter during procurement: ABB’s Advant Controller 450 documentation identifies part number 3BSE019958R1 for a single S100 I/O bus extension serving a subrack in position 3 or 5, using the specified DSTK 195 cable arrangement. Confirm the cabinet, subrack position, and cable requirements against the installation documentation before ordering.
The ABB DSBC 176K05 belongs to the S100 I/O hardware ecosystem used in legacy ABB Advant control installations. These systems may be found in established process-control environments where replacing a connection kit requires preserving the original bus topology and cable routing. A part-number match is a necessary starting point, but it does not establish that every kit with the DSBC 176 designation is interchangeable. ABB lists other S100 I/O connection kits, including DSBC 176K01 and DSBC 176K06, as separate catalog items. Their distinct order numbers should not be treated as equivalent without checking the intended subrack and cable arrangement.
When sourcing the ABB 3BSE019958R1 DSBC 176K05, check the full part number on the label and verify the included components, physical condition, and storage history. If the kit is offered as new surplus, request confirmation that it is unused and that the original kit contents are present. For a running plant, comparing the supplied parts with the original bill of materials is a practical safeguard against ordering a kit that has the correct family name but the wrong cable configuration.
Product Introduction
The ABB DSBC 176K05 connection kit supports designated S100 I/O bus-extension installations in legacy Advant control systems. ABB documentation associates 3BSE019958R1 with a cable arrangement for subrack positions 3 and 5.
Before replacement, verify the installed subrack location, required cable types, and kit contents. Do not substitute another DSBC 176 kit based on the family designation alone.

Frequently Asked Questions
Q1: What is the ABB 3BSE019958R1 DSBC 176K05 used for?
It is a connection kit for ABB I/O bus-extension installations. ABB documentation identifies it for a specified cable arrangement connecting to an I/O subrack at position 3 or 5.
Q2: Is DSBC 176K05 the same as the DSBC 176 bus extender board?
No. DSBC 176K05, order number 3BSE019958R1, is the connection kit. DSBC 176, order number 3BSE019216R1, is the bus extender board. They have different catalog identities and functions.
Q3: Can I hot-swap this kit while the system is running?
Do not assume that it can be hot-swapped. The kit participates in the physical bus and cable arrangement, and ABB’s product identification alone does not establish a live-replacement procedure. Follow the applicable system maintenance instructions and plant isolation requirements before disconnecting any components.
Q4: Does DSBC 176K05 require particular firmware or software?
No kit-specific firmware requirement is established by the available product description. Compatibility depends primarily on the installed I/O architecture, subrack configuration, and required connection arrangement. Check the controller and system documentation for the installation in question.
Q5: Can it replace DSBC 176K01 or DSBC 176K06?
Not automatically. ABB lists the three kits under separate order numbers. Compare the original bill of materials, subrack position, and required cables before accepting a substitute.
Q6: How can I verify authenticity and condition when buying new surplus?
Request clear photographs of the ABB label, complete order number, packaging, and supplied components. Ask the seller to state whether the item is unused surplus, refurbished, or used. A matching label is useful evidence but does not independently prove authenticity or storage condition.
Q7: Does the kit contain programmable logic or require user programming?
It is identified as a connection kit, not a programmable controller. Its role is to provide the specified physical connections for the I/O bus extension. No user-programmable logic function is established for the kit itself.
