Compatible Replacement & Equivalent Models
The TB805 (3BSE008534R1) is a dedicated bus outlet for ABB S800 I/O. The following models may serve as functional equivalents or replacements depending on your system configuration:
- ABB TB806 – Extended bus outlet variant for larger I/O clusters
- ABB TB807 – Bus outlet with redundancy support
- ABB TB820V2 / 3BSE013208R1 – Modulebus Modem (upstream communication module, often paired with TB805)
- ABB TB840A / 3BSE037760R1 – PROFIBUS-DP bus interface, alternative for DP-based architectures
- ABB CI854A / 3BSE030220R1 – PROFIBUS-DP master interface for AC800M (system-level alternative)
Note: Always verify firmware version, bus protocol, and rack compatibility before substituting. Contact Konmask for pre-sales compatibility verification.
Why Choose the Original Model
- Guaranteed Compatibility: Factory-matched to ABB S800 I/O mechanical and electrical bus interface standards

Typical Applications
- ABB AC800M / AC800F distributed control system (DCS) I/O expansion
- Advant OCS (Operator Control Station) field I/O bus connections
- PROFIBUS-DP segment termination and outlet in process automation
- Power generation, oil & gas, pulp & paper, and chemical plant automation
- Retrofit and upgrade projects on legacy ABB Advant Controller 450/410 systems
System Compatibility
- Control Systems: ABB AC800M, AC800F, Advant Controller 450, Advant Controller 410
- I/O Platform: S800 I/O (AI810, AO810, DI810, DO810, etc.)
- Bus Protocol: Modulebus, PROFIBUS-DP
- Software: Compatible with ABB Control Builder M, Advant Builder
- Not compatible with: S900 I/O series, AC500 PLC platform, or third-party non-ABB bus systems without adaptation
Selection Guide
Use the following criteria to confirm TB805 3BSE008534R1 is the correct part for your application:
- Step 1 – Identify your control system: Confirm you are running AC800M, AC800F, or Advant Controller series.
- Step 2 – Verify bus protocol: TB805 supports Modulebus. If your segment uses PROFIBUS-DP exclusively, consider TB840A or CI854A.
- Step 3 – Check I/O cluster size: TB805 supports standard cluster configurations. For larger clusters, evaluate TB806 or TB807.
- Step 4 – Confirm redundancy requirements: TB805 is non-redundant. For redundant bus outlet needs, specify TB807.
- Step 5 – Review firmware baseline: Ensure your system firmware is compatible with the TB805 hardware revision in stock.

Replacement & Compatibility FAQ
Q: Can TB805 replace TB806 directly?
A: Not always. TB806 supports a larger I/O cluster. Verify your cluster node count before substituting.
Q: Is 3BSE008534R1 the only reference number for TB805?
A: Yes, 3BSE008534R1 is the primary ABB catalog reference. Some legacy documents may list it under earlier revision codes — contact us to cross-reference.
Q: Can I use TB805 on a PROFIBUS-DP-only segment?
A: TB805 is primarily a Modulebus outlet. For pure PROFIBUS-DP segments, TB840A or CI854A is recommended.
Q: Do you provide a warranty?
A: Yes — 90-day functional warranty on all units. Extended warranty available for volume orders.
Q: Can you source discontinued or obsolete ABB parts?
A: Yes. Konmask specializes in sourcing obsolete and hard-to-find industrial automation components. Submit an RFQ with your part number.
