Electrical Requirements#

WARNING – Electric Shock and Fire Hazard / Risque de choc électrique et d'incendie

Unapproved power supplies may cause electric shock or fire or both. Serious injury or death may occur.

  • You must use power supplies that meet the Safety Extra Low Voltage (SELV) and Limited Power Source (LPS) or the Electrical Source 1 (ES1) and Power Source 2 (PS2) requirements.
  • If you use a powered hub or powered switch, they must meet the above requirements.

Les blocs d'alimentation non approuvés peuvent causer des décharges électriques ou des départs de feu, ou les deux. Celles-ci représentent un risque de mort ou de blessure grave.

  • Vous devez utiliser un bloc d'alimentation conforme aux exigences Safety Extra Low Voltage (SELV) et Limited Power Source (LPS) ou Electrical Source 1 (ES1) et Power Source 2 (PS2).
  • Si vous utilisez un hub alimenté ou un switch alimenté, ils doivent être conformes aux exigences ci-dessus.
NOTICE – Incorrect voltage can damage the camera.

You must supply camera and I/O power within the safe operating voltage ranges specified below.

Do not use negative voltage for an I/O line.

Camera Power#

  • Power supply via USB 3.0 port: Power must comply with the Universal Serial Bus 3.0 specification.
  • Power supply via I/O connector: The operating voltage is 12–24 VDC. As a minimum, 10.8 VDC must be supplied. To avoid damaging the camera, a maximum of 30 VDC must not be exceeded.

Info

  • Always power on the host computer first, even if you supply power via I/O connector. Otherwise, the host computer may not recognize the camera as a USB device.
  • If you supply power via I/O connector and USB 3.0 port, power supply via the I/O connector takes precedence.
  • When changing power supply from I/O connector to USB 3.0 port or vice versa, the camera is power-cycled and restarted.

Opto-Coupled I/O Input Line#

Voltage Description
30 VDC Absolute maximum. This voltage must never be exceeded. Doing so may damage the camera and voids the warranty.
0–24 VDC Safe operating range.
0–1.4 VDC Indicates a logical 0 (with inverter disabled).
>1.4–2.2 VDC Region where the logic level transition occurs; the logical state is not defined in this region.
>2.2 VDC Indicates a logical 1 (with inverter disabled).
  • Input current (high-level): <15 mA internally limited
  • Input current (high-level): >5 mA required to drive the opto-coupler

General Purpose I/O Lines#

NOTICE: Applying incorrect electrical signals to the camera's GPIO line can severely damage the camera.

Before you connect any external circuitry to the GPIO line, use the Line Mode feature to configure the line for input or output.

Make sure to apply appropriate input or output signal voltages as specified below.

Operation as Input#
Voltage Description
30 VDC Absolute maximum. This voltage must never be exceeded. Doing so may damage the camera and voids the warranty.
0–24 VDC Safe operating range. The minimum external pull-up voltage is 3.3 VDC.
0–0.8 VDC Indicates a logical 0 (with inverter disabled).
>0.8–2.0 VDC Region where the logic level transition occurs; the logical state is not defined in this region.
>2.0 VDC Indicates a logical 1 (with inverter disabled).
  • Input current (high-level): <100 μA
  • Input current (low-level): <5 mA sink current from the GPIO input line without exceeding 0.8 VDC.
Operation as Output#
Voltage Description
30 VDC Absolute maximum. This voltage must never be exceeded. Doing so may damage the camera and voids the warranty.
3.3–24 VDC Safe operating range.
<3.3 VDC Unreliable GPIO output.
  • Internal pull-up resistor: ≈650 Ω, with open collector. Many applications will have to provide an additional pull-up resistor.
  • Residual voltage ("on" state): ≈0.4 VDC at 50 mA and 25 °C (77 °F) housing temperature. Actual residual voltage depends on operating temperature, load current, and production spread of electronic components.
  • Leakage current: <60 µA. Actual leakage depends on operating temperature and production spread of electronic components.
  • Maximum load current: 50 mA
  • Minimum load current: Not specified. Consider the following:
    • Leakage current will have a stronger effect when load currents are low.
    • Propagation delay of the output increases as load currents decrease.
    • Higher-impedance circuits tend to be more susceptible to EMI.
    • Higher currents cause higher voltage drops in long cables.

For more information about the I/O lines, see the I/O Control section.

Cable Requirements#

USB 3.0 Cable#

  • Use a high-quality USB 3.0 cable with a Micro-B plug.
  • To avoid EMI, cables must be shielded, as specified in the USB 3.0 standard.

For more information about recommended USB 3.0 cables, see the Recommended Accessories for Basler USB 3.0 Cameras document.

I/O Cable#

  • The I/O cable must be shielded.
  • The I/O cable must have a cross-section of at least 0.14 mm² (close to AWG26).
  • Use twisted pair wire cables.
  • Maximum recommended cable length: 10 m
  • Camera-side connector: M8 6-pin male, coding A-standard, according to IEC 61076-2-104
  • Proximity to strong magnetic fields should be avoided.
  • Basler recommends using I/O cables from the Basler cable portfolio:
