Overview
Fan Status Monitor board enables independent, remote monitoring of up to four EC fans equipped with an ‘open collector type’ tachometer.
The fan fault signal is generated when the speed of any active fan, in two consecutive measurements, falls below the minimum or exceeds the maximum speed value. These minimum and maximum values can be adjusted via MIN RPM and MAX RPM potentiometers.
The general fault condition is indicated by a low voltage Solid State Relay and the corresponding fan status LED indicator.
