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 board.
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#
The GigE RJ45 PoE interface board supports Power over Ethernet (PoE). Power must comply with the IEEE 802.3af specification.
The voltage converter has an efficiency of at least 75 % at 2 W and above. To calculate the power requirement of the whole camera, divide the power requirement of the camera module by the efficiency of the interface board, i.e.
Formula
Camera power requirement = Power requirement of camera module / Interface board efficiency
Example: 2 W / 75 % = 2.7 W
Output Power#
The GigE RJ45 PoE interface board is designed for a maximum output power of 6 W. This power must not be exceeded.
Opto-Coupled I/O Input Line#
| Voltage | Description |
|---|---|
| 30 VDC | Absolute maximum. This voltage must never be exceeded. Doing so may damage the board and voids the warranty. |
| 0–24 VDC | Safe operating range. |
| 0–1.1 VDC | Indicates a logical 0 (with inverter disabled). |
| >1.1–2.2 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 GPIO lines can severely damage the board.
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 board and voids the warranty. |
| 0–5 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 board 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.
General Purpose I/O Voltage#
The GPIO and GPO lines are internally connected to pin 4 via a 3.6 kΩ pull-up resistor. See Circuit Diagrams.
To increase the output voltage of the GPO or the GPIO configured as output beyond 3.3 V, supply external voltage to pin 4.

Cable Requirements#
Ethernet Cable#
- Use a high-quality Ethernet cable. Use of shielded Cat 5e or better cables with S/STP shielding is recommended.
- Use either a straight-through (patch) or a cross-over Ethernet cable.
- Proximity to strong magnetic fields should be avoided.
- Basler recommends using Ethernet cables from the Basler cable portfolio.
I/O Cable#
- The I/O cable must have a cross-section of at least 0.09 mm² (close to AWG28).
- The I/O cable will not be used to supply power. The GigE RJ45 PoE interface board supports Power over Ethernet (PoE).
- Maximum recommended cable length: 10 m
- Recommended connector: TE 1-338095-0 (crimp type) or WR-MM 690157001072 (ribbon type)
- Close proximity to strong magnetic fields should be avoided.
FFC Cable#
Basler recommends using dart Flexible Flat Cables.
Physical Interface#
