Acquisition Trigger Input
The reader 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.
l To trigger from an NPN type photoelectric sensor or PLC output, connect COMMON IN to +24 VDC and connect
IN 0 to the output of the photoelectric sensor. When the output turns ON, it pulls TRIGGER down to 0 VDC, turning
the opto-coupler ON.
l To trigger from a PNP photoelectric sensor or PLC output, connect IN 0 to the output of the photoelectric sensor
and connect COMMON IN to 0 VDC. When the output turns ON, it pulls TRIGGER up to +24 VDC, turning the
opto-coupler ON.
