  • SCADA (Modbus, IEC-101/102, IEC-104 gateway)
  • PLC interface (Base node up to 2000 smart meters)
  • Extended temperature range (-25 to 70 °C)
  • Complies with electrical safety regulations & EMC
  • DMVPNs, VLANs and QoS for critical services
  • Dual-SIM redundancy


The Regesta Smart PLC router family brings today's most advanced corporate IP network protocols to the world of smart grids and telemetry. Specially designed to interconnect IP-based networks with PLC technology, it is ideal for the deployment of intelligent centralized telemetry solutions that require reliable communications with PLC smart meters. It takes full advantage of Teldat's advanced internetworking software (CIT) to provide state-of-the-art communications security with encryption, authentication management and access control for protection against instrusion attacks. Combined with Teldat or third-party SNMP-based management tools, it is ideal for large-scale deployments, where for example, the auto-provisioning feature enables deployments without the intervention of dedicated IT personnel.
