4G/5G Routers

The Westermo Merlin series consists of industrial 4G/5G routers designed for secure and reliable cellular communication within critical infrastructure, energy supply systems, and industrial automation. These routers feature a range of VPN capabilities, advanced security, and support for industrial protocols—including Modbus, IEC 60870-5-104, IEC 61850, and DNP3 (depending on the model). When used in combination with Activator—Westermo’s ‘zero-touch commissioning’ software—the Merlin devices provide a cost-efficient and reliable solution for large-scale projects.
