34 Basler ace USB 3.0
5.8 Opto-isolated Output (Pin 4, Line 2)
The camera is equipped with one dedicated opto-isolated output line designated as Line 2. The
output line is accessed via the 6-pin connector on the back of the camera (pin 4).
In addition, the camera has two direct-coupled GPIO lines, Line 3 and Line 4, that can both be used
as output lines. They are described in Section 5.9 on
page 36 .
The opto-isolated output line has the advantage of being distinctly more robust against EMI than a
GPIO line used as an output. However, when using the opto-isolated output line, the delays
involved are longer than for a GPIO line.
5.8.1 Voltage Requirements
The following voltage requirements and information apply to the opto-isolated I/O output line (pin 4
of the 6-pin connector; Line 2).
Note: The maximum current allowed through the output circuit is 50 mA .
NOTICE
Voltage outside of the specified range can cause damage.
The recommended voltage range

for the opto-isolated output line differs from the recommended voltage range for the
opto-isolated input line (see Section 5.7.1 on
page 32 ) and .

for the I/O input lines of Basler ace USB 3.0 cameras can differ from the recommended
voltage ranges for the I/O input lines of other Basler cameras.
You must supply power within the specified voltage range.
Voltage Significance
+30.0 VDC Absolute maximum; the camera can be damaged if the absolute maximum is exceeded.
+3.3 to +24 VDC Recommended I/O output supply voltage range.
< +3.3 VDC The I/O output can operate erratically.
