High-Speed Outputs
The vision system features two built-in, high-speed outputs, which are optically isolated. The high-speed outputs can be
used as either NPN (current sinking) or PNP (current sourcing) lines.
Specification
Description
Voltage
26.4VDC maximum through external load
Current
50mA maximum sink or source current
OFF state leakage current 100µA
External load resistance 470 Ohms to 10K Ohms
Each line rated at a maximum 50mA, protected against over-current, short circuits and transients from
switching inductive loads. High current inductive loads require an external protection diode.
Delay
1
25μs (maximum due to opto-isolators turning ON).
For NPN lines, the external load should be connected between the output and the positive supply voltage (<26.4VDC).
The output pulls down to less than 3VDC when ON, which causes current to flow through the load. When the output is
OFF, no current flows through the load.
For PNP lines, the external load should be connected between the output and the negative supply voltage (0VDC).
When connected to a 24VDC power supply, the output pulls up greater than 21VDC when ON, and current flows through
the load. When the output is OFF, no current flows through the load.
1
Delay when opto-isolators turn OFF depends on the load to which the output is connected. With a 470 Ohm load, the maximum delay will be
200μs.
