Goldeye G/CL Technical Manual V4.1.1
In 2 - opto-isolated (pin 11)
In 2
is optically isolated and can be used in electrically noisy environments to
prevent false trigger events. To complete the trigger circuit, connect trigger ground
to
Isolated In GND
. Compared to the non-isolated trigger,
In 2
has a longer
propagation time.
Isolated input block diagram
The inputs can be connected directly to the system for voltages up to 24 VDC. An
external resistor is not necessary.
Goldeye G/CL isolated input delay and minimum pulse width
The minimum pulse width for all Goldeye G/CL cameras is:
Trigger signal
Input current
Trigger input voltage: V
in
(low):
0.0 V to 1.0 V
Trigger input voltage: V
in
(high):
3.0 V to 24.0 V
Input current to be expected:
5 mA
