The intelligate control board was designed to work in all Ramset model operators.It is a state-of-the-art microprocessor controlled PCB with more options and functions than any other gate operator control board in the industry. The control board is powered by a separate mounted 24V AC transformer. This allows no necessary board modifications between 110V AC and 220V AC single-phase applications. Some of the functions of the Intelligate control board are: 0-60 seconds automatic close timer, self adjusting ERD with low and high settings, constant warning, pre-warning, one pass, open & close delay, left/right hand operation, plug-in loop detectors and RS485 three wire master/slave connection.
