EXOcompactArdo freely programmable controllers

Small and compact controller with different types of communication, with or without built-in display. EXOcompact is equipped with various communication ports. Therefore it can either act as a stand-alone unit or be integrated with Arrigo BMS or other SCADA systems. User-friendly tools are available for flexible handling and easy access via the web server.
