ABB VBX01T-VBX01B

Product introduction

The VBX01T-VBX01B is a fiber optic transceiver pair from ABB, designed to extend Ethernet networks in industrial environments by converting electrical signals to optical signals and vice versa. As a reliable communication solution in ABB’s industrial networking portfolio, the VBX01T (transmitter) and VBX01B (receiver) work together to transmit data over multimode fiber, overcoming electromagnetic interference (EMI) and distance limitations of copper cables.

Ideal for connecting distributed control systems (DCS) and PLCs across factory floors, the VBX01T-VBX01B ensures stable 100 Mbps communication even in noisy environments with heavy machinery, motors, or high-voltage equipment. Whether linking remote I/O cabinets to a central controller or connecting HMI panels in hazardous areas, the VBX01T-VBX01B provides secure, interference-free data transmission, enhancing the reliability of industrial automation networks. Its compact design allows easy integration into control cabinets, making it a versatile choice for various industrial applications.

Core advantages and technical highlights

Immunity to electromagnetic interference

The VBX01T-VBX01B uses fiber optic transmission, eliminating EMI and radio frequency interference (RFI) that plague copper-based Ethernet. In a steel mill, where large motors and welding equipment generate intense electrical noise, the transceiver pair maintains stable communication between the 1SVR011718R2500-powered control system and remote sensors, preventing data loss or corruption that could cause production delays.

Extended transmission distance

With a 2 km range over multimode fiber, the VBX01T-VBX01B connects devices across large facilities without signal degradation. In a wastewater treatment plant spanning multiple buildings, it links the main control room PLC to remote pump stations, avoiding the need for expensive signal repeaters. This range exceeds typical copper Ethernet limits (100 m), reducing infrastructure costs in sprawling industrial sites.

Industrial-grade durability

Operating from -40°C to +75°C, the VBX01T-VBX01B withstands extreme temperatures in outdoor cabinets or unconditioned industrial spaces. In a desert solar power plant, where daytime cabinet temperatures reach 70°C, the transceiver pair continues transmitting performance data from solar trackers to the central management system. Its rugged construction also resists vibration and shock, ensuring reliability in mobile machinery applications.

Typical application scenarios

In an automotive manufacturing plant, the VBX01T-VBX01B serves as a critical communication link between the main production line control system and a remote paint shop:

• The VBX01Tconnects to the central Ethernet switch in the main control room, converting electrical signals from PLCs and AI815 3BSE052604R1 modules to optical signals.
• Fiber optic cable runs 1.5 km through conduit to the paint shop, where the VBX01Bconverts the optical signal back to electrical for the paint robot controllers and ventilation system monitors.

This setup ensures interference-free transmission of control signals and sensor data, even near high-voltage paint curing ovens. The VBX01T-VBX01B’s EMI immunity prevents false triggers of safety systems, while its extended range eliminates the need for intermediate network devices, simplifying the network architecture.

In a chemical processing facility, the transceiver pair connects a hazardous area control panel (Zone 2) to the safe-area DCS. By using fiber optics, it avoids the risk of sparking from electrical connections in explosive environments, enhancing plant safety while maintaining reliable data flow.

Installation, commissioning and maintenance instructions

Installation preparation

Before installing the VBX01T-VBX01B, ensure the DIN rail is securely mounted in a clean, dry cabinet within the -40°C to +75°C range. Use a torque screwdriver (0.5 Nm) to attach both units to the rail, leaving 10 mm clearance between them for airflow. Connect the VBX01T to the Ethernet source via an industrial RJ45 cable, and the VBX01B to the destination device similarly. For fiber connections, use ST connectors to link the transceivers, ensuring the fiber is properly stripped and polished to minimize signal loss. Power both units with a 24 V DC supply like the 1SVR011718R2500, verifying correct polarity to prevent damage.

Maintenance suggestions

Weekly checks of the VBX01T-VBX01B involve verifying the green LED indicators for power and link activity; a red LED indicates a fault (check cable connections or fiber integrity). Inspect fiber connectors quarterly for dirt or damage, cleaning with lint-free wipes and isopropyl alcohol if needed. Test signal strength annually using an optical power meter to ensure transmission levels remain within specifications. If a transceiver fails, replace it with an ABB-approved spare, reusing existing fiber and Ethernet cables after verifying their integrity.
