Description
📋 Product Overview
The ABB TC515V2, part number 3BSE013284R1, is an Advant Fieldbus 100 (AF100) twisted-pair-to-twisted-pair repeater. It is designed to extend or segment an AF100 twisted-pair communication network while maintaining the bus connection between two cable sections.
ABB lists TC515V2 specifically as an AF100 Twisted pair to twisted pair repeater, with 24 VDC power and 50 V rated isolation. It belongs to the same AF100 communication family as the TC513V1 twisted-pair/coax modem and TC514V2 twisted-pair-to-optical-fiber repeater.

🔌 Operating Function
TC515V2 works between two sections of an AF100 twisted-pair network.
A typical arrangement can be represented as:
AF100 Network Section 1 → TC515V2 → AF100 Network Section 2
The repeater receives the AF100 communication signal on one twisted-pair side and regenerates it onto the other side. This makes the device useful when an AF100 installation requires additional network reach or a physical separation between cable sections.
The front-panel indicators provide a practical first-level diagnostic:
- P — power status
- Tx1 / Rx1 — communication activity on twisted-pair side 1
- Tx2 / Rx2 — communication activity on twisted-pair side 2
These indicators can help technicians determine whether the unit is powered and whether communication activity is present on either side of the repeater.
🔧 Installation & Configuration
1. Confirm the AF100 network
TC515V2 should only be installed where the communication architecture is based on ABB Advant Fieldbus 100 twisted-pair cabling.
It should not be treated as a standard Ethernet switch, Ethernet media converter, or generic RS-485 repeater.
2. Mount on DIN rail
ABB’s AF100 manual specifies DIN-rail mounting for the TC515 family. Install the unit securely inside the control cabinet or suitable enclosure.
3. Connect the two AF100 cable sections
The unit has separate twisted-pair connections for the two sides of the repeater.
Pay attention to:
- L+ / L− conductors
- Shield connections
- Correct cable polarity
- AF100 termination
- Cable routing
- Shield continuity
The manual identifies Wieland 8213 S/4 GF OB connectors for the twisted-pair connections.
4. Apply 24 VDC
The ABB catalog specifies a 24 VDC supply for TC515V2. Verify the cabinet power supply and polarity before energizing the unit.
5. Check communication LEDs
After power-up, the P indicator should show the power condition. During active AF100 communication, Tx/Rx indicators can be used to check activity on each network side.
If one side shows no activity, inspect the cable, shield, termination, upstream device, and fieldbus configuration before replacing the repeater.
🏭 Application Scenarios & Typical Problems
TC515V2 is particularly useful in legacy ABB automation systems where replacing the complete AF100 communication infrastructure would be impractical.
Typical applications include:
- ABB Advant OCS systems
- AF100 process-control networks
- Legacy ABB controller installations
- Distributed I/O communication
- Long or segmented AF100 twisted-pair networks
- Control cabinet communication
- Maintenance replacement of obsolete AF100 repeaters
Common field problems
No communication on one side
Check the corresponding twisted-pair cable, shield, termination, connector seating, and the upstream AF100 device.
Power LED is off
Verify the 24 VDC supply, polarity, fuse, and cabinet power distribution.
Only one side shows Tx/Rx activity
This can indicate a problem with the opposite cable section or its connected AF100 devices. The LED indication should be used together with the actual network architecture rather than as a standalone fault diagnosis.
Intermittent communication
Check shield connections, cable routing, loose terminals, oxidation, and termination components. AF100 installations should use the appropriate ABB cable and termination arrangement.
🧰 Maintenance Recommendations
For legacy AF100 equipment, preventive inspection is often more useful than replacing communication hardware unnecessarily.
Recommended checks include:
- Inspect both twisted-pair connectors.
- Check for loose or oxidized terminals.
- Verify the 24 VDC supply.
- Inspect cable shielding and grounding.
- Check AF100 termination components.
- Keep high-voltage power wiring separated from fieldbus cables.
- Observe Tx/Rx LEDs during normal operation.
- Check the cabinet for excessive heat, dust, or moisture.
- Record the TC515V2 article number before ordering a replacement.
When troubleshooting, replace the repeater only after confirming the cable and power supply. A fieldbus communication fault can easily originate from a connector, termination, or cable rather than the repeater itself.
❓ Frequently Asked Questions
Q1: What is ABB TC515V2 used for?
It is an AF100 twisted-pair-to-twisted-pair repeater used to connect and regenerate communication between two sections of an ABB Advant Fieldbus 100 network.
Q2: What is the ABB part number?
The article number is 3BSE013284R1. ABB identifies this article as TC515V2.
Q3: Is TC515V2 an Ethernet repeater?
No. It is designed for ABB Advant Fieldbus 100 twisted-pair communication. It should not be substituted with a conventional Ethernet repeater.
Q4: What power supply does it use?
ABB specifies a 24 VDC supply.
Q5: What is the rated isolation?
ABB specifies 50 V rated isolation for TC515V2.
Q6: Does it support optical fiber?
Not directly. TC515V2 is the twisted-pair-to-twisted-pair version. For twisted-pair-to-optical-fiber conversion, ABB lists the TC514V2, article 3BSE013281R1.
Q7: What is the difference between TC514V2 and TC515V2?
TC514V2 converts between AF100 twisted pair and optical fiber. TC515V2 repeats between two AF100 twisted-pair sections.
Q8: Is TC515V2 still relevant for replacement projects?
Yes, particularly when maintaining existing Advant OCS / AF100 installations where the original fieldbus infrastructure remains in service. ABB documentation continues to identify the device as an AF100 communication component.

📌 Application Summary
The ABB TC515V2 3BSE013284R1 is a dedicated AF100 twisted-pair-to-twisted-pair repeater for ABB Advant OCS and related legacy fieldbus installations. Its job is straightforward but important: maintain communication between two AF100 twisted-pair network sections while providing electrical isolation between the sides.
Its 24 VDC supply, 50 V rated isolation, DIN-rail mounting, dual twisted-pair interfaces, and Tx/Rx status indication make it a practical service component for maintaining existing AF100 networks.
For replacement work, match the complete ABB article number 3BSE013284R1 rather than relying only on the physical appearance of the repeater. Also verify the AF100 cable, termination, shield, and power arrangements before commissioning.
