ABB TC514V2 3BSE013281R1 AF100 Twisted Pair to Opto Repeater Modem

The ABB TC514V2 (part number 3BSE013281R1) is an AF100 Twisted Pair to Opto Repeater that bridges twisted pair and optical fiber segments in Advant Fieldbus 100 networks. It provides reliable media conversion and acts as a repeater to extend network reach. Each unit is equivalent to approximately 150 meters of cable length in bus calculations.

Powered by 24V DC with 50V rated isolation, the TC514V2 features a compact plastic housing, LED status indicators for easy diagnostics, and an adjustable optical power switch. It is fully compatible with ABB 800xA and Advant Master systems, delivering secure, high-integrity communication for process control applications.

• Media Conversion & Repeater Functionality: Seamlessly converts between AF100 twisted pair and optical fiber, extending network segments with full transparency.

• Extended Distance: One unit equals ~150m of cable; supports optical links up to 1000m+ depending on power setting.

• Robust Design: 24V DC power supply, 50V isolation, IP20 protection; resistant to electromagnetic interference typical in industrial settings.

• Diagnostic LEDs: Clear indicators for Power (P, green), Twisted Pair Tx1/Rx1 (amber), and Optical Tx2/Rx2 (amber).

• Optical Power Adjustment: Switch positions 1-2 (50% power, shorter cable) or 3-4 (100% power, longer cable).

• Easy Installation: Wieland connectors for twisted pair and power; ST-style optical connectors.

• Proven Reliability: Part of ABB’s Advant Fieldbus 100 ecosystem, widely used in 800xA systems.

• RoHS Exemption Note: Exempted per relevant EU directives for industrial equipment.

• Retrofit and expansion of existing Advant Fieldbus 100 installations

Q: What is the main function of the ABB TC514V2?A: It serves as a Twisted Pair to Optical Fiber repeater/modem for Advant Fieldbus 100, enabling media conversion and network extension.

Q: What power supply does it require?A: 24V DC with 50V rated isolation.

Q: How do I adjust optical power?A: Use the rotating switch: positions 1-2 for 50% (cable<1000m), 3-4 for 100% (longer distances).

Q: What are the LED indicators?A: P (Power, green), Tx1/Rx1 (Twisted Pair, amber), Tx2/Rx2 (Optical, amber).

Q: Is it compatible with ABB 800xA?A: Yes, fully integrated with Advant Fieldbus 100 in 800xA and legacy Advant systems.

Q: What is the equivalent cable length impact?A: Each TC514V2 counts as approximately 150 meters when calculating total bus length.
