Merlin Series

The Merlin 4400 series of versatile cellular routers is designed from the ground up to achieve best-in-class Cybersecurity both in hardware and software. A TPM chip (Trusted Platform Module) keeps cryptographic keys secure. Secure Boot guarantees that the unit boots using only software that is signed and trusted by Westermo. A 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 network. 

The Merlin 4600 series of versatile cellular routers provide high speed data network connectivity for demanding industrial, smart grid and trackside applications. Coupled with the Zero Touch deployment software Activator, it provides cost-effective, reliable, and consistent onboarding of routers in large-scale projects.

This compact, rugged unit is suited to tight spaces. It meets the requirements of IEC 61850-3 Class 1 Medium Voltage substation and also railway trackside EN 50121-4. The power supply and Ethernet ports benefit from a high level of galvanic isolation, up to 4 kVrms. Its high MTBF and wide temperature range support maximum service life.

To achieve best-in-class cybersecurity, the Merlin 4600 series is equipped with a TPM (Trusted Platform Module) chip that keeps cryptographic keys secure. Secure Boot ensures that the unit boots using only software that is signed and trusted by manufacturer. A set of cybersecurity tools is available as standard including VPN and stateful Firewall support for data security and user authentication.

The built-in industrial protocol gateway enables several devices using different protocols to be accessed via a common protocol interface. The unit supports up to 6 digital inputs and 2 outputs for local control or monitoring. Support for more digital inputs and outputs is possible using external modules.
