Industrial networks rely on dependable, easy-to-deploy connectivity to keep systems communicating reliably.

In environments where uptime, speed of installation, and durability are critical, Weidmüller’s BLB Series unmanaged Ethernet switches, available through Pacific Automation, provide a straightforward and robust networking solution for industrial applications.

Designed to reduce complexity without compromising performance, the BLB Series delivers essential industrial Ethernet functionality in a compact, rugged form factor.

 

Simple, Reliable Industrial Networking

The BLB Series is designed as a cost-effective alternative to managed switches, offering essential network features without the need for software configuration. These unmanaged switches support PROFINET CC-A and EtherNet/IP networks, making them well suited to common industrial automation architectures.

Key built-in functions include Quality of Service (QoS), Broadcast Storm Protection (BSP), and LLDP filtering, helping ensure stable communication and predictable network behaviour in industrial environments.

 

DIP Switch Configuration for Fast Setup

Unlike managed switches that require configuration software and commissioning time, BLB Series switches use simple DIP switch settings. This allows installers to enable or adjust performance features directly on the device, without laptops or programming tools.

This plug-and-play approach makes the BLB Series ideal for machine automation, factory networks, mining operations, process industries, and building infrastructure, particularly where rapid deployment and minimal complexity are priorities.

 

Built for Harsh Industrial Environments

Industrial networking equipment often operates in demanding conditions. The BLB Series is designed to perform reliably across a wide operating temperature range from –40 °C to +75 °C, making it suitable for use in outdoor installations, transport systems, and remote locations.

High EMC compatibility helps protect against electrical interference, while robust mechanical and environmental certifications provide confidence in long-term performance. These features make the BLB Series well suited to applications such as offshore facilities, wind farms, mobile equipment, and marine environments.

 

Installation-Focused Design

Installation efficiency is a key consideration in industrial projects. BLB Series switches feature a tool-free locking foot and PUSH IN terminals, enabling fast, secure mounting and wiring on site.

Packaging is plastic-free and recyclable, supporting more sustainable installation practices. The overall design focuses on reducing installation time, simplifying maintenance, and minimising disruption during upgrades or retrofits.

Flexible Options for Diverse Applications

The BLB Series is available in a variety of configurations to suit different network requirements. Options include 5, 8, 16, and 24 ports, with support for Fast Ethernet or Gigabit Ethernet, as well as models with SFP slots for fibre connectivity.

With extensive approvals and a rugged design, a single BLB product family can be used across multiple applications and environments, helping simplify procurement, reduce inventory, and standardise network infrastructure.

 

Part of a Complete Automation Ecosystem

BLB Series switches integrate seamlessly with other Weidmüller automation components, including UC20 controllers, power supplies, and industrial security routers. Together, they form a cohesive and reliable automation ecosystem, supporting everything from local machine networks to plant-wide communication systems.

A Practical Ethernet Solution for Industrial Automation

For engineers and operators seeking reliable industrial Ethernet without unnecessary complexity, the BLB Series offers a practical solution:

 

  • Unmanaged industrial Ethernet switches with essential network features

  • DIP switch configuration for fast, tool-free setup

  • Wide temperature range and high EMC resistance

  • Installer-friendly mounting and wiring

  • Flexible port and media options for diverse applications

 

Whether expanding an existing network or designing a new automation system, the BLB Series delivers dependable connectivity that performs in demanding industrial environments.
