Strobe Output
The camera features one built-in strobe output, which is optically isolated. The strobe output can be used as either an
NPN (current sinking) or PNP (current sourcing) line.
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.
Delay
1
30µs (maximum due to opto-isolators turning ON).
For NPN lines, the external load should be connected between the STROBE output and the positive supply voltage
(+24VDC nominal). COMMON should be connected to the negative supply voltage (0VDC). The STROBE output pulls
down to less than 3VDC when ON, which causes current to flow through the load. When the STROBE output is OFF, no
current flows through the load.
For PNP lines, the external load should be connected between the STROBE output and the negative supply voltage
(0VDC). When COMMON is connected to the positive supply voltage (+24VDC nominal), the STROBE output pulls up to
greater than 21VDC when ON, and current flows through the load. When the STROBE 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 240 Ohm load, the maximum delay will be
35µs.
