Speed signal /2
–
Speed-proportional, square-wave signal for external monitoring of the fan motor speed
– 2, 3, or 6 pulses per revolution
– Open-collector signal output
– Extremely wide operating voltage range
– Easy adaptation to user interface
– Connection via separate cable
– The sensor signal also serves as a major comparison variable for setting and maintaining
the setpoint speed for interactive or controlled cooling with one or more interconnected
fans.
