Features Optimized for Modern IIoT Systems
With the new firmware update, the switch operates directly within a PLC-controlled network, eliminating the need for external gateways. Users can easily perform basic configurations and access critical diagnostic data through the familiar Fieldbus interfaces, allowing for unified network management in industrial settings with mixed protocols.
The switch features high-speed gigabit backbone ports for efficient data transfer, supporting large data transfers such as video streams. The switch also features standard 10/100 Mbit/s ports for fast and reliable connectivity. The upgraded switch offers a flexible configuration option through web-based management or a USB interface.
Designed to accommodate outdoor control cabinet installation, the switch features an IP65/IP67/IP69K-rated enclosure that can withstand extreme temperatures ranging from -40 °C to +70°C and shock, vibration, and UV light exposure. The switch is designed to operate reliably in various power environments, with a wide input voltage range (8-30 VDC) and robust electrical protection features, including load-dump protection, to safeguard against power surges and other electrical transients.

Managed Switches in Industry
Many simple, isolated industrial networks rely on unmanaged switches. These devices share network traffic between PLCs, HMIs, drives, and robotic controllers. Still, some of the features in a managed switch are unnecessary when outside network access is impossible.
This new managed switch is ideal for modular situations, when the isolation of a network may not be guaranteed over the entire service life of the equipment. It includes advanced networking features such as NAT routing and VLAN support, which can consolidate large, modular equipment cells into more logically segmented networks for simple communication with outside networks. Firewall software provides a secure connection that can block malicious traffic and remove unnecessary messages to increase communication speed. A real-time network load monitor provides easy detection and diagnosis of network congestion.
Ideal for Robotics and Modular Machines
In high-speed manufacturing environments, such as robotic operations in the automation industry, the switch offers an ideal option for fast tool changing due to its 150 ms quick connect and startup capabilities, thereby minimizing delays. Its compact design, featuring modular connectors, simplifies wiring, allowing seamless integration into modular machine architecture without bulky enclosures.
The updated TBEN-L-SE-M2 managed switch's PLC-friendly Fieldbus protocol makes the solution ideal for industries seeking efficient, secure, future-proof systems that meet the demands of modern industrial applications.
