Introduction The RTU202 is a extremely low power Logger/Telemetry unit designed to operate external power or self power for up to 5 Years * (SMS Alert only for float switch application) self powered operation. . This telemetry unit has built in LTE modem CAT1 and 50 channel GPS for timing and tracking. Built in logger memory (32MBYTE non volatile flash memory) and a FAT32 file systems MicroSD (4GB ) . Interface supports Serial, RS485, Mod Bus Serial, Optional Ethernet TCP-IP RJ45 (support Modbus-TCP) The unit is light weight, weather proof, draw less than 100uA in special deep power down mode for special custom mode. Unit can be power external from 7VDC to 28VDC. Cable connector are IP68 rated. Built In Battery Backed Real Time Clock/Calendar. All Event are date and time stamps to record the actual time of alarm. Real Time Clock/ Calendar has its own Lithium Battery Power Source for at least 10 years of Clock Calendar and Alarm Functions. The battery is independent of the primary battery for the entire unit. LARGE DATALOG MEMORY (Up to 64GB) Onboard Solid State Flash Memory provides 32MBYTE of Datalogging memory that is not affected by battery. MicroSD is equipped with 16GB of FAT32 SDCard, and 32KB Infinite read/write Ferromagnetic memories. Interfacing to External Equipments and Sensors Customisation are welcome to interface the logger telemetry to external sensors including: TT-100 Digital water Level Sensors (0—6 Meters , +/- 0.25% for Level sensing) or any 4-20mA/RS485 sensors. Insitu Water Level MultiParameter probes (PH, Level, DO)
