General-Purpose Input

The vision system features one built-in general-purpose input, which is optically isolated. The input can be configured as

either NPN (current sinking) or PNP (current sourcing) lines.

Specification

Description

Voltage

ON: 15 to 28V DC (24DC nominal)
OFF: 0 to 5VDC (11.5VDC nominal threshold)

Current
(Typical)

ON: 2.6mA to 4.9mA from 15 to 28V input
OFF: < 830µA for < 5VDC input
Resistance:~6 Kohms

Delay

1.11ms maximum latency between leading edge of trigger and start of acquisition. Input pulse should be
minimum of 1ms wide.

l

For NPN lines, connect COMMON IN to +24VDC and connect IN 1 to the output of the photoelectric sensor or

PLC. When the output turns ON, it pulls IN 1 down to 0VDC, turning the opto-coupler ON.

l

For PNP lines, connect IN 1 to the output of the detector and connect COMMON IN to 0VDC. When the output

turns ON, it pulls IN 1 up to +24VDC, turning the opto-coupler ON.
