Acquisition Trigger Input
The vision system features one acquisition trigger input, which is optically 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: 20 to 28VDC (24VDC nominal) OFF: 0 to 3VDC (8VDC nominal threshold) |
| Current |
ON: 1.9 to 3.0mA from 20 to 28V input. OFF: < 300µA for <3VDC input. Resistance: ~10 kOhms |
| Delay1Maximum latency is based on a 1µs trigger debounce. | 72µs maximum latency between leading edge of trigger and start of acquisition. Input pulse should be minimum of 1ms wide. |
- The Breakout cable can be used to trigger from an NPN photoelectric sensor or PLC output. Connect TRIGGER+ to +24VDC and connect TRIGGER- to the output of the photoelectric sensor. When the output turns ON, it pulls TRIGGER- down to 0VDC, turning the opto-coupler ON. For more information, refer to Breakout Cable Specifications.

The Breakout cable can also be used to trigger from a PNP photoelectric sensor or PLC output. Connect TRIGGER+ to the output of the photoelectric sensor and connect TRIGGER- 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.
