When normal input operation
“Trigger Input Anode +” can be used as driving source and
“Trigger Input Cathode
-
” can be connected to ground
As the opto-coupler is an
“AC” type the connection can be inverted
When voltage is applied to trigger input, then “Trigger
-I
n” is active.
Voltage range of trigger input:
The current limiter (I_lim) for photodiode forward is 10mA.
Minimum voltage levels of trigger input:
Trigger input is active when the voltage applied to the input pins is higher than 3V.
Maximum levels of trigger input:
Maximum voltage to the input should not be higher than 30V
