Acquisition Trigger Input
The vision sensor features one acquisition trigger input that is opto-isolated. The acquisition trigger input can be configured to trigger from either an NPN (current sinking) or PNP (current sourcing) device.
| Specification | Description |
|---|---|
| Voltage | ON: 15 to 24VDC (24VDC nominal) OFF: 0 to 5VDC (0VDC nominal) |
| Current |
3.6 mA @ 12VDC, 7.5 mA @ 24VDC Resistance: ~5.48 kOhms |
| Delay | 1.45 ms maximum latency between leading edge of trigger and start of acquisition. Input pulse should be a minimum of 1 ms wide. |
To trigger from an NPN (pull-down) type photo-detector or PLC output, connect TRIGGER to the output of the photoelectric sensor or PLC and connect INPUT COMMON to +24VDC. When the output turns on, it pulls TRIGGER down to 0VDC, turning the opto-coupler on. For more information, refer to Breakout Cable Specifications.
To trigger from a PNP (pull-up) type photo-detector or PLC output, connect TRIGGER to the output of the photoelectric sensor or PLC and connect INPUT COMMON to 0VDC. When the output turns on, it pulls TRIGGER up to 24VDC, turning the opto-coupler on. For more information, refer to Breakout Cable Specifications.
