Electrical Specification of trigger and encoder inputs:
input voltage: Signal LOW
-0.3V – 0.8V
Input voltage: Signal HIGH
2.2V – 5V
input current:
N/A
limiting resistor:
none
reverse voltage protection:
none
Image trigger on rising or falling input signal works as before – see section 6.5.3 for details.
The trigger inputs and outputs are very sensitive and not galvanically separated. Opto
isolation of the driving circuit is therefore strongly recommended. The following page
shows suitable circuits for trigger inputs and outputs.
!
Please note that inputs and outputs are not protected against over current. The outputs are
neither protected against short circuit nor reverse voltage spikes from inductive loads.
Recommended driving circuit for the trigger inputs:
Trigin B
ST6.2
(Trigin A)
Same circuit
as for Trigin A
ST6.1 (5V)
ST6.4
(Trigin B)
Pins 2 and 4 have
to be connected!
