Product Introduction
The DSDI110AV1 3BSE018295R1 is an S800 16-channel 24 VDC digital input module used with AC800M and 800xA systems. It is not a generic PLC card you can drop into any rack. It belongs to the S800 I/O family, so it must sit on the correct S800 termination unit and be recognized by the controller hardware configuration.I have seen this part confused with older Advant / MOD300 DSDI110A cards. They share a similar name, but they are not interchangeable. The 3BSE018295R1 version is an S800 module; the older DSDI110A belongs to the Advant S100 I/O platform. If the wrong platform is ordered, the module may look correct on paper but will not fit the termination unit or download into the controller configuration.
Quality SOP & Tech Pitfalls
The Lab Report (SOP):
- Visual inspection — housing, connector edge, nameplate, order code 3BSE018295R1, revision label.
- Connector check — verify module bus contacts and termination unit interface pins.
- Power-up verification — install on a known-good S800 termination unit; confirm module power and status LEDs.
- Channel check — apply safe 24 VDC signals to selected inputs; verify channel indication.
- Diagnostics check — confirm the module is detected by the controller or configuration tool without hardware fault flags.
- Record revision, LED status, connector condition, and any physical damage.
- Pack in anti-static bag with desiccant; seal for shipment.
The Engineer’s Warning (Pitfalls):
The biggest risk with this part is platform confusion. DSDI110AV1 3BSE018295R1 belongs to S800 I/O, while the older DSDI110A belongs to Advant S100 I/O. They cannot be swapped. Also check the termination unit. S800 modules require the correct TU base, and mechanical keying must match before insertion.Do not force the module into the base. If the code key or locking mechanism does not align, the controller may reject it or the module bus contacts can be damaged. I have seen a module pushed in slightly off-angle; it powered up, but several channels reported intermittent faults until the base and module pins were reseated.
Installation & Configuration Guide
1. Pre-Installation ️
- Obtain work permit and confirm controller and I/O station status.
- Do not remove a live S800 module unless the site maintenance procedure allows hot swap.
- Photograph the termination unit type, module position, cable tags, and LED status.
- Verify the replacement order code 3BSE018295R1 and revision.
2. Removal
- Confirm the module slot address in the controller configuration.
- If permitted, release the module locking mechanism.
- Withdraw the module straight out without rocking it.
- Keep the termination unit wiring untouched unless replacement is required.
3. Installation
- Verify the termination unit matches the S800 DI module requirement.
- Check mechanical keying before insertion.
- Insert the module firmly until it seats fully.
- Confirm the module is recognized by the controller hardware configuration.
4. Power-On & Testing
- Check module status LEDs after insertion.
- Force or monitor known field signals to confirm channel mapping.
- Verify that no hardware fault or configuration mismatch appears in the controller.
- Monitor the module through at least one stable operational cycle before closing the cabinet.
Compatible Replacement Models
- Drop-in Replacement: ABB DSDI110AV1 3BSE018295R1, same S800 revision. Preferred option.
- ️ Verify Before Use: Other S800 16-channel 24 VDC DI modules may be compatible, but channel grouping, diagnostics, and termination unit compatibility must be confirmed in the ABB hardware manual.
- Not a Direct Substitute: Older DSDI110A Advant S100 I/O cards, non-S800 digital input modules, or generic 24 VDC PLC cards.
Frequently Asked Questions (FAQ)
Is DSDI110AV1 3BSE018295R1 an S800 module?
Yes. It is an S800 I/O digital input module for AC800M / 800xA systems.Can it replace DSDI110A 57160001-AAA?
No. DSDI110A 57160001-AAA belongs to the older Advant S100 I/O platform and is not interchangeable with the S800 DSDI110AV1.How many channels does it have?
16 digital input channels, 24 VDC.Can it be hot-swapped?
S800 I/O supports hot swap by design, but you should still follow the site maintenance procedure and confirm the controller configuration before removing a live module.What termination unit does it need?
It must be installed on the correct S800 termination unit. Confirm the exact TU type from the ABB S800 hardware manual or the existing station layout.What is the warranty condition?
Surplus units typically carry a functional warranty unless stated otherwise. That covers DOA and bench-tested failures, not site miswiring, incorrect termination units, or controller configuration errors.
