4.6.2 External Pulse Input
The unit can be operated and controlled by an external signal, from either a sensor or a machine signal like
an output from a printing press, re-winder or others. This will allow the stroboscope to flash in sync with the
target object’s rotational speed.
The input signal will have the following characteristics.
Input frequency: 60 - 10,000 FPM (1 – 160 Hz)
Input pulse width: over 50us
Delay angle: 0 - 359°
(
every 1° )
Delay time: 0 - 999ms (every 1ms)
Please connect with open collector output (below 1V (ON voltage)) or no-voltage contact output (approx.
11mA current)
