Frequently Asked Questions
Q: What is the Banana PI RT9400 PoE PD module used for?
A: The RT9400 is a Power over Ethernet (PoE) Powered Device (PD) module that extracts power from a standard Cat5 Ethernet cable (IEEE 802.3af standard) and converts it to a regulated DC output (3.3V, 5V, 12V, or 24V). It is commonly used to power IP cameras, wireless access points, VOIP phones, security systems, and other network-connected devices without requiring a separate power supply.
Q: What output voltages are available for the RT9400 module?
A: The RT9400 series is available in four output voltage variants: 3.3V (up to 2A), 5V (up to 2A), 12V (up to 1A), and 24V (up to 0.5A). The output can also be fine-tuned using an external resistor connected to the ADJ pin.
Q: What does "isolation model" mean for the RT9400?
A: The "isolation model" refers to the transformer isolation between the input (PoE Ethernet side) and output (DC power side) of the module. The RT9400 provides 1500V peak isolation voltage, which protects connected devices from electrical interference and improves overall safety in network installations.
Q: Is the RT9400 RoHS compliant?
A: Yes, the Banana PI RT9400 PoE PD module is fully RoHS compliant, meaning it meets international standards for restriction of hazardous substances in electronic equipment.
