4.7.2 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)
4.7.3 External pulse output
The unit will also output a signal that is related to the flash rate of the unit. This signal can be used to control
additional stroboscopes so that each flashes at the same rate or to send a pulse to data collectors.
External circuit: Open collector output, Voltage below DC30V, Current below 30mA
Output pulse width: Approx. 200us
