Description
Product Overview
The ABB 3BSE019926R1 DSDI 110AK13 is a 32-channel digital input kit for ABB S100 I/O systems, with a catalog-rated input voltage of 24 VDC. Its function is to acquire discrete field signals—such as contact states and other on/off conditions—and make those signals available to the control system. The kit is intended for use in compatible ABB Advant control-system configurations, including documented Advant Controller 450, AC 460, MasterPiece 200/200-1, and related S100 I/O environments. The complete kit designation matters during replacement because the supplied connection hardware is part of the intended installation arrangement.
The ABB DSDI 110AK13 is suited to maintenance and spare-parts planning for established process-control systems that use S100 I/O. ABB’s S100 I/O documentation describes digital input hardware with optoisolated channels and configurable input filtering, with signal acquisition handled through cyclic scanning or interrupt-based processing where supported by the specific board. These family-level capabilities should not be treated as confirmation that every feature or setting is available in every kit configuration. Before ordering, verify the installed input board, field signal voltage, connection-unit type, and required terminal arrangement against the system documentation.
When sourcing the ABB 3BSE019926R1 DSDI 110AK13, confirm the full order number and whether the kit includes all components required by the original installation. Ask the supplier to identify the item’s condition and provide photographs of the labels and connections. If the kit is replacing a failed input assembly, inspect the field wiring and signal source as well as the module itself. Incorrect field voltage, grounding issues, or wiring faults can produce unreliable input readings even when replacement hardware is functional.
Product Introduction
The ABB DSDI 110AK13 acquires 24 VDC digital signals through 32 input channels in compatible S100 I/O installations. It is intended for use within the ABB Advant control-system ecosystem.
Before commissioning, verify the field voltage, input wiring, channel arrangement, and connection-unit configuration against the applicable ABB hardware documentation.

Frequently Asked Questions
Q1: What is the ABB 3BSE019926R1 DSDI 110AK13 used for?
It is a 32-channel digital input kit for ABB I/O systems, specified for 24 VDC field signals. It allows the control system to acquire discrete states from compatible field devices.
Q2: Can this kit accept 48 VDC signals?
Do not assume so. The DSDI 110AK13 catalog description specifies 24 VDC. ABB lists a separate DSDI 120AK03 kit for 48 VDC applications, so verify the required voltage before selecting a replacement.
Q3: Can I hot-swap the DSDI 110AK13?
ABB describes hot replacement as a feature of its I/O module range. However, confirm the exact installation procedure and system conditions before replacing the kit live. Consider field signal behavior, process consequences, and the specific connection hardware.
Q4: Does this kit require specific firmware or programming?
No independent firmware requirement is established by the kit’s catalog description. Compatibility depends on the installed controller, I/O configuration, and system software. The application logic and input mapping are handled at the control-system level.
Q5: Can DSDI 110AK14 or DSDI 110AK15 replace the AK13 version?
Not automatically. Although these products belong to the same family, their kit configurations may differ. Compare the original bill of materials, field voltage, connection-unit arrangement, and controller documentation before approving a substitute.
Q6: How can I verify authenticity and condition when buying surplus?
Request photographs of the ABB label and complete part number, details of the included components, and a written condition statement. Confirm whether the item is unused surplus, refurbished, or previously installed. A matching label alone does not prove authenticity or completeness.
Q7: What should I check if the input signals are unstable after replacement?
Check the field supply voltage, terminal wiring, signal common, grounding, input-filter settings, and the actual switching thresholds specified for the installed board. Also verify that the connection unit matches the intended I/O configuration. Replacing the kit alone may not correct a field-wiring or signal-quality problem.
