Keeping industrial systems connected requires networking hardware that’s dependable, efficient, and easy to install. For engineers and technicians working in harsh environments, every minute counts, and complexity can be costly. That’s where Weidmüller’s BLB Series unmanaged switches come in.
Designed for simplicity and performance
The BLB Series offers a cost-effective alternative to managed switches, supporting PROFINET CC-A and EtherNet/IP networks while delivering essential functions such as Quality of Service (QoS), Broadcast Storm Protection (BSP), and LLDP filtering.
Unlike managed switches that require software configuration, the BLB Series uses simple DIP switch setup, letting users tailor performance features instantly without programming or software tools. This makes it ideal for machine and factory automation, mining, process industry, and building infrastructure where dependable, plug-and-play performance matters most.
Built for harsh conditions
From offshore platforms to wind farms and transport systems, the BLB Series is made for extreme environments.
Each model works across a wide temperature range from –40°C to +75°C and features high EMC compatibility for resistance to electrical interference. The switches are certified to meet stringent mechanical and environmental standards, giving users confidence in their long-term reliability.
Whether you’re wiring up a factory network or deploying in mobile or marine systems, these switches are perfect to thrive where others fail.
Efficient by design
Weidmüller has designed the BLB Series with the installer in mind. A tool-free locking foot and PUSH IN terminals make mounting and wiring fast and secure, while plastic-free, recyclable packaging supports more sustainable site practices.
Each product is optimised for quick installation and minimal maintenance, helping reduce downtime, save space, and simplify upgrades in the field.
One series, endless possibilities
Available in a range of port configurations (5, 8, 16, and 24 ports) and with options for Fast or Gigabit Ethernet and SFP slots, the BLB Series delivers the flexibility needed for diverse applications. Its extensive approvals and rugged construction mean a single product family can serve multiple environments, simplify supply chains, and reduce inventory costs.
Built to work with your system
Pairing perfectly with Weidmüller’s UC20 Controls, power supplies, and industrial security routers, the BLB Series forms part of a complete, reliable automation ecosystem. From local network communication to full-scale plant integration, it’s designed to keep your systems connected efficiently and securely.
