The Selec TT412 is a time totaliser that counts and displays accumulated running time on a 6-digit readout. In a marine control system it records how long a connected machine or circuit has been active, counting upward in seconds, minutes or hours. It takes its count input from mains, a potential free contact or a PNP sensor, keeps the total in memory for 10 years, and offers two changeover (DPDT) outputs plus remote reset. These figures give machinery maintenance a running-hours record to work from. The unit is supplied in New Open Box condition.
