Description
Product Overview
The ABB 3BSE019956R1 DSBC 176K01 is a connection kit designed for a single S100 I/O bus extension to an I/O subrack in supported ABB Advant control-system configurations. It is an accessory assembly, not a standalone controller or a general-purpose communication interface. ABB’s Advant Controller 450 product documentation identifies this order number for the subrack No. 1 arrangement using a TK575 cable measuring approximately 2.5 m (8.3 ft). The listed kit components are DSBC 176, DSTC 176, and TK575. Verify these items against the system bill of materials before ordering, particularly when replacing a kit that has been in service for years.
The ABB DSBC 176K01 is intended for installations using the S100 I/O architecture, which appears in legacy Advant control environments and related ABB control-system configurations. Its practical role is to provide the specified hardware and cable arrangement needed to extend the I/O bus to the appropriate subrack. Correct selection depends on the physical system layout, subrack number, and required cable configuration—not simply the DSBC 176 family name. ABB lists DSBC 176K06 and DSBC 176K05 as separate connection kits for other subrack arrangements, so they should not be assumed interchangeable with the K01 version.
When sourcing the ABB 3BSE019956R1 DSBC 176K01, confirm the full order number, kit contents, and condition. For new-surplus inventory, ask whether all specified components are included and whether the item has been stored in suitable conditions. A matching part number alone does not establish that a kit is complete or suitable for the installed cabinet. For older control systems, checking the original installation drawings before dispatch can prevent a costly mismatch during a planned shutdown.

Frequently Asked Questions
Q1: What is the ABB DSBC 176K01 used for?
It provides the specified connection hardware and cabling for a single I/O bus extension to subrack No. 1 in the documented Advant Controller 450 configuration.
Q2: Is DSBC 176K01 the same as the DSBC 176 bus extender board?
No. DSBC 176K01, order number 3BSE019956R1, identifies the complete connection kit. DSBC 176, order number 3BSE019216R1, identifies the bus extender board included in the kit configuration.
Q3: Can I hot-swap this kit while the controller is running?
Do not assume hot-swapping is permitted. The kit connects the physical I/O bus, and the available product information does not establish a live-replacement procedure. Follow the applicable ABB maintenance instructions and plant isolation procedures.
Q4: Does DSBC 176K01 require specific firmware?
No kit-specific firmware requirement is established in the product data. Compatibility should be checked against the installed controller, I/O hardware, subrack layout, and system documentation.
Q5: Can DSBC 176K01 replace DSBC 176K05 or DSBC 176K06?
Not as a direct substitution without verification. K01 is documented for subrack No. 1, K06 for positions 2 and 4, and K05 for positions 3 and 5. Their cable arrangements differ.
Q6: How do I verify authenticity when purchasing new-surplus stock?
Request photographs of the original ABB label, order number, packaging, and all included components. Have the supplier confirm whether the kit is unused surplus, refurbished, or used. A matching part number alone does not prove that the kit is genuine or complete.
Q7: Does this kit contain programmable logic or require programming?
It is a physical connection kit, not a programmable logic controller. Its function is to connect the I/O bus extension using the specified components and cables. Controller configuration and application logic remain separate system-level concerns.
