Central Units for ECO Automation System and Sensor-Actuator Gateways for Public Institutions, Municipalities, Universities, Communities, Research, Industry, IoT, and IIoT Customers

The central units/gateways of the "gray" ESERA 500 series provide a comprehensive solution for demanding applications and industries. Highest security, extended temperature range, reliability, and flexibility are guaranteed.

The ESERA central units or gateways have been a standard for over 10 years in industrial, IoT, IIoT, and automation. They automatically and independently connect sensors and actuators on a 1-Wire basis to your control software, PLC control, cloud service, and many other application solutions in professional automation solutions. The focus is on plug-and-play functionality, allowing the control units to be operational within minutes. Easy commissioning saves you valuable time.

Advantages and Features of the 500 Series Central Units/Gateways

  • Temperature Range: The gateways offer an extended temperature range, ideal for applications in protected outdoor areas, cold storage, and similar environments.
  • Multiprotocol Gateway: These devices serve as multiprotocol control units for OT, IoT, and general automation.
  • Security: The central units are continuously adapted to current security requirements, with encrypted and certified updates as standard equipment. Compliance with the new Machinery Directive 2006/42/EC is a top priority.
  • Functions: From this series onward, the full functions of the central units are available without limitations. Licenses or function expansions, such as the maximum number of zones in smaller series, are already activated and require no additional steps.
