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 | 28VDC maximum through external load. |
| Current | 100mA maximum sink current. |
| OFF state leakage current 100µA maximum. | |
| External load resistance 240 Ohms to 10 kOhms. | |
| Maximum 100mA, protected against over-current, short circuit and transients from switching inductive loads. High current inductive loads require an external protection diode. | |
| Delay1Delay when opto-isolators turn OFF depends on the load to which the output is connected. With a 240 Ohm load, the maximum delay will be 35µs. | 30µs (maximum due to opto-isolators turning ON). |
For NPN lines, the external load should be connected between the output and the positive supply voltage (+24VDC nominal). HS COMMON should be connected to the negative supply voltage (0VDC). The outputs pull down to less than 3VDC when ON, which causes current to flow through the load. When the outputs are 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 HS COMMON is connected to the positive supply voltage (+24VDC nominal), the outputs pull up to greater than 21VDC when ON, and current flows through the load. When the outputs are OFF, no current flows through the load.
