OPEN 600 EMS basic24

Native BACnet controller for small HVAC systems

The OPEN 600 EMS basic24 controller is the most cost-effective BACnet controller in the DEOS product range and was specially developed for micro applications in the HVAC sector – for example for ventilation systems with heating and cooling function or 4 regulated heating circuits. This cloud-ready controller can also be used for other applications in the areas of heating, ventilation, air conditioning, district heating, single and multi-room control. With 24 integrated digital and analogue inputs and outputs, the OPEN 600 EMS basic24 controller guarantees high flexibility in your projects. In addition, system graphics can be displayed on the controller via the integrated HTML5 web server OPENview. The integrated firewall completes the package and protects the DDC controller from cyber attacks.

System openness

The system openness and the diverse interfaces and protocols make the OPEN EMS controllers exceptionally flexible to use. In order to meet project requirements, they can be extended via the CAN-bus by up to 198 input and output modules. The IO modules can be positioned up to 5 km from the controller.

Time-saving programming

You can choose whether you want to program the OPEN EMS freely or use the preconfigured and time-saving DEOS libraries. By using the template or macro library, programming work can be reduced by up to 90% and programming errors avoided.

Integrated HTML5 web server

The powerful integrated HTML5 web server OPENview is available on every controller from the OPEN EMS product range. You can access them decentrally via the Internet or Intranet. OPENview enables graphical visualisation and operation of your system even via remote access, which is not only simple but also saves you valuable time.

Integrated Service & Security Center

With the OPEN EMS Service & Security Center and the integrated IT security functions, your DDC controllers and your building automation are protected against unauthorised access and cyber attacks from outside. The installation and setup of the firewall is intuitive and can be implemented via preconfigured security modes without any in-depth IT knowledge.
