50 Basler ace USB 3.0
5.7 Opto-isolated Input (Pin 2/Line 1)
The camera is equipped with one dedicated opto-isolated input line designated as Line 1. The input
line is accessed via the 6-pin connector on the back of the camera (pin 2, see Figure 30).
In addition, the camera has two direct-coupled GPIO lines, Line 3 and Line 4, that can both be used
as input lines. They are described in Section 5.9 on page 54.
5.7.1 Electrical Characteristics
The following voltage requirements and information apply to the camera’s opto-isolated I/O input
line (pin 2 of the 6-pin connector; Line 1).
Note: A minimum current of 5 mA must be provided to the I/O input line.
The opto-isolated input line has the advantage of being distinctly more robust
against EMI than a GPIO line used as an input. However, when using the opto-
isolated input line, the delays involved are longer than for a GPIO line.
NOTICE
Voltage outside of the specified range can cause damage.
The recommended I/O supply voltage range
for the opto-isolated input line differs from the recommended voltage range for the opto-
isolated output line (see Section 5.8.1 on page 52) and direct-coupled GPIO lines
(Section 5.9 on page 54).
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 when the absolute maximum is
exceeded.
+0 to +24 VDC Recommended I/O input voltage range.
+0 to +1.4 VDC The voltage indicates a logical 0.
> +1.4 to +2.2 VDC Region where the transition threshold occurs; the logical status is not defined in this
region.
> +2.2 VDC The voltage indicates a logical 1.
