I/O Specifications

Cable and connector specifications and connection examples for the acquisition trigger input and the high-speed
outputs are provided in the following sections.

Acquisition Trigger Input

The vision system features one acquisition trigger input, which is optically isolated. You can configure the acquisition
trigger input to trigger from an NPN (current sinking) or PNP (current sourcing) device.

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 the
page 25.
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

Maximum latency is based on a 1µs trigger debounce.
Description
63µs maximum latency between leading edge of trigger and
start of acquisition. Input pulse should be minimum of 1 ms
wide.
81µs maximum latency between leading edge of trigger and
start of acquisition. Input pulse should be minimum of 1 ms
wide.
116µs maximum latency between leading edge of trigger and
start of acquisition. Input pulse should be minimum of 1 ms
wide.
