TRU
TRU (Tank Relay Unit) is the unit used to start or stop external equipment in any alarm scenario occurring in the tank automation system. There are relay circuits in the TRU. Thanks to the TRU parameters in the Asis Tank automation system, the TRU unit is programmed to activate or deactivate which relay output for which tank and which alarm condition. TRU relay outputs are also included in the circuit connection of the external equipment (siren, searchlight, etc.) that is desired to be stopped or operated, and when the alarm occurs in the tanks, the TRU stops or operates the external equipment on the information from the tank automation system. Thus, it allows users to automatically manage peripheral equipment as well as display data. It automatically deactivates when the alarm condition disappears.
