General-Purpose Inputs
The vision system features three built-in general-purpose inputs, which are optically isolated. The inputs can be
configured as either NPN (current sinking) or PNP (current sourcing) lines.
Note
: Since all general-purpose inputs share a common ground (INPUT COMMON), all connected input devices
must be either current sinking or current sourcing.

Description
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.
For NPN lines, to utilize an input, connect INPUT COMMON to +24VDC and attach the photoelectric sensor or PLC
output to the corresponding input.
For PNP lines, to utilize an input, connect INPUT COMMON to 0VDC and attach the photoelectric sensor or PLC output
to the corresponding input.
1
Maximum latency is based on a 1µs trigger debounce.
