The main task of the data logger RC12 is an automatic acquisition of signals from various sensors of physical quantities, processing of such information, and recording them with a specified time interval in embedded nonvalatie memory. Additionally, RC12 communicates with a management system and can be configured to generate the warning messages and alarms.


The software allows data logger to calculate dew point temperature, freezing point temperature of liquid covering the surface or to generate alarm messages: a warning of icing, fire hazard (forest), slippery road, a side wind, fog, hoarfrost, water lever exceeding user configurable level and sharp sudden rise of precipitation. The messages can be sent to the management center or directly to the active elements of a system, such as variable message signs.


RC12 registrar is fully configurable in terms of quantity and type of supported sensors and other parameters like i.e. data measurement intervals, rules of alarm generation and various destinations for alarm datagrams.


In case of improper device operation, build-in-self-diagnosis system is able to automatically reset the recorder or any external device. It happens for example on long-time power shortage or disruption in energy supply. After power resume, the device itself recovers full functionality.
