Image acquisition trigger input
An opto-isolated image acquisition trigger input ( × 1) is integrated into a vision sensor.
Image acquisition can be started using a sink type device or source type device.
To start the image acquisition with these devices, "Camera" needs to be selected from the pull-down list of "Trigger" under
"Edit Acquisition Settings" in In-Sight Explorer.
To trigger from the output of a sink type photoelectric sensor or programmable controller, connect 'Trigger' of a breakout cable
to the output of the photoelectric sensor or an output module, and connect 'Input common' to 24 V DC.
When the output is turned ON, 'Trigger' is pulled down to 0 V DC and the opto-coupler of the sensor is turned ON.
To trigger from the output of a source type photoelectric sensor or programmable controller, connect 'Trigger' of a breakout
cable to the output of the photoelectric sensor or an output module, and connect 'Input common' to 0 V DC.
When the output is turned ON, 'Trigger' is pulled up to 24 VDC and the opto-coupler of the sensor is turned ON.
