I/O Specifications
Cable and connector specifications and connection examples for acquisition trigger input, general-purpose inputs, high-
speed outputs and RS-232 serial communications 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.

Voltage
ON: 24VDC ± 10% (24VDC nominal)
OFF: 0 to 3VDC (0VDC nominal)
Current
ON: 6.6mA to 9.8mA
OFF: <1mA
Resistance: ~3.2 kOhms
Delay
1
90µs maximum latency between leading edge of trigger and start of acquisition. Input pulse should be a
minimum of 1ms wide
The Breakout cable can be used to trigger from an NPN photoelectric sensor or PLC output. Connect INPUT COMMON
to +24VDC and TRIGGER to the output of the photoelectric sensor. When the output turns ON, it pulls INPUT COMMON
down to 0VDC, turning the opto-coupler ON. For more information, refer to the
The Breakout cable can also be used to trigger from a PNP photoelectric sensor or PLC output. Connect INPUT
COMMON to 0VDC and TRIGGER to the output of the photoelectric sensor. When the output turns ON, it pulls TRIGGER
