Hirschmann RED25 Switches

New family of entry-level redundancy switches designed for industrial automation applications in need of cost-effective and high-end redundant network solutions. In addition to support for various redundancy technologies like PRP, HSR, and DLR, the Hirschmann RED25 switches have comprehensive built-in security features. The switches are also customizable based on specific port needs or environmental factors, such as temperature range.

  • Maximum network uptime – interruption-free data communication supported by various redundancy protocols
  • Flexible, versatile design – easy customization through two port configurations, various security features and field-exchangeable fiber modules
  • Cost effective ideal for entry-level industrial network needs and economical installations, including retrofits

Your Benefits

Permanent access to systems and machines is an absolute must for profitable business systems. The RED25 family provides maximum productivity and network uptime. This value stems from interruption-free data communications based on parallel redundancy protocol (PRP) and high-availability seamless redundancy (HSR). Other redundancy technologies like Rapid Spanning Tree Protocol (RSTP) and Media Redundancy Protocol (MRP) allow the switches to connect to existing networks and Device Level Ring (DLR) redundancy ensures a recovery time within milliseconds.

The switches are designed to handle high ambient temperatures and meet precise time synchronization requirements.

RED25 is an ideal choice for those who need a Fast Ethernet, entry-level redundancy switch designed specifically for operation in extreme environmental conditions.

The features offered with these switches are particularly suited for use in industrial automation applications that require cost-effective, high-end redundancy topologies. RED25 switches are a great fit for automotive, manufacturing and machine building industries.

Other applications in which the RED25 switches can also be used include consumer packaged goods and water and wastewater treatment facilities.

Product Description

The RED25 family of switches offers maximum flexibility and a future-proof network design. This is an affordable solution for industrial network engineers, system integrators and machine builders working on entry-level applications.

on Hirschmann Operating System (HiOS) software, RED25 supports several redundancy technologies, while offering a comprehensive range of security features.

This Fast Ethernet (FE) switch is offered in two, four-port versions:

  • Four FE TX ports
  • Two FE TX ports, plus two FE small form-factor pluggable (SFP) ports

The SFP-based fiber support enables a flexible network structure by allowing to change fiber ports in the field. A comprehensive set of security features also offers all-around network protection.

The RED25 switches guarantee a reliable network of applications with rigorous real-time requirements in accordance with IEEE 1588 v2. Further features include an extended operating temperature range from -40 ˚C to +70 ˚C, broad immunity to electrostatic discharges and high-vibration resistance.
