Westermo Merlin 4407 - Industrial Cellular Router

4xETH, 2xSerial, Dual-SIM, GNSS

The Merlin 4400 is a series of robust cellular routers designed for demanding industrial and critical infrastructure applications, such as trackside, substation automation and heavy industry.

The routers are certified for installation in both medium voltage substations (IEC 61850-3 Class 1) and trackside (EN 50121-4) and are built for top-of-class availability, security and life-time expectancy.  

Best-in-class Cyber Security

The Merlin series of routers are designed from the ground up to achieve best-in-class Cyber security both in hardware and software. A TPM chip (Trusted Platform Module) keeps cryptographic keys secure and Secure Boot guarantees that the unit boots using only software that is signed and trusted by Westermo.

A modern set of cybersecurity tools is available as standard. High security VPNs, stateful inspection firewall, user authentication and 802.1x are just a few of the features available to keep the device secure both locally and when transmitting data over the internet or private networks.

Industrial protocol support

Legacy serial (RS-232/485) ports allow the Merlin 4400 to be used in applications where it is necessary to migrate from modems to an IP infrastructure. The built-in industrial protocol gateway enables several devices using different protocols to be accessed via a common protocol interface.

Zero-touch management 

The Merlin 4400, like all the members of the Merlin family, is compatible with the Activator zero-touch deployment software. The Activator software ensures that configurations are generated and deployed from a central server, reducing configuration mistakes and increasing efficiency during the installation phase of a project.

Rugged and compact

This compact unit is suited to tight spaces. Its high MTBF, wide temperature range and voltage supply ensure the Merlin can deal with the demands of industrial, smart grid and trackside applications.
