ISY4 IoT-Gateway-RS485

The ISY4 IoT-Gateway with I/O and RS485 is the universal gateway of the future. All data from the Master can be easily exchanged with the cloud or other IoT systems. Many integrated safety features offer the highest IT security even for sensitive applications.

Quick Facts

  • Ethernet and USB interface
  • "node-red" integrated
  • integrated LTE modem (4G, 3G, 2G)
  • comprehensive cloud and server protocols
  • extended temperature range and for harsh environments

The gateway is suitable for secure connection of the ISYGLT Master to an IoT cloud solution (supports comprehensive cloud and server protocols) or as an interface to other IoT systems or IoT devices. For highest IT security, the gateway establishes a VPN connection to the cloud systems. Many other additional safety features are already provided to enable use in even the most sensitive applications.

This allows all states to be transmitted from the master and external controls to be carried out easily and securely. In addition, interfaces such as KNX/IP, Modbus TCP, OPC UA, MQTT, REST and many others can be implemented. The direct use of SMS services, e-mail, TELEGRAM etc. is also easily possible.

The integrated "node-red" programming platform opens up countless possibilities for functions and for data exchange with any system. The graphical programming makes it very easy to enter the world of IoT. The entire configuration is done via the web interface with a browser.

The connection to the Internet can be made via an Internet access provided by the customer or via the integrated LTE modem. The device is suitable for wall or DIN rail mounting.


Possible applications:

  • Connection of ISYGLT systems to a cloud system with evaluation
  • Easy integration of digital assistants or AI for optimisation
  • Interface to other systems or IoT applications
