High-Speed Outputs - Cognex In-Sight Micro Series Installation Manual

High-Speed Outputs

The In-Sight Micro 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
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.
Each line rated at a maximum 100mA, protected against over-current, short circuit and transients from
switching inductive loads. High current inductive loads require an external protection diode.
12
Delay 5µs (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.

Delay 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.

If HS OUT 1 is configured as a Strobe output type within In-Sight Explorer, the maximum strobe latency is 5µs. For more information, refer to
