The DFR0428 is an two-channel full-Gigabit PoE access control module with standard IEEE 802.3af/at/bt compliant power supply. The module is based on a NXP LPC1343 processor. This PoE access control module is qualified with various PoE interface chipset such as TI PoE, Atmel Powerline Layer, and Microchip PoE. With embedded password protection for secure authorization, the module can easily be integrated in a secure network.
The DFR0428 module can be used in many applications, such as smart home, surveillance, access control, home automation, security systems, industrial IOT, and retail systems. The module is highly integrated and does not require extra power adapter for operation. The module is compliant with the IEEE 802.3af/at/bt PSE “powered device” power supply protocol, allowing the system to be powered over Ethernet. The module is easy to set up and requires no extra hardware to be installed.
The DFR0428 module uses a variety of techniques to ensure reliable and secure communication. It uses common control line signaling (CCL), voltage signal transmission (VST), and data packet transmission (DPT) to ensure the transmission and receiving of data and commands. It supports addressable communication (I2C) and other peripherals, such as I2C, UART, GPIO, SPI, and USB for device configuration. It also supports PoE powered devices (PD) management and authentication.
The DFR0428 module is equipped with a PoE port management unit (PMU) and a power supply interface controller (PIC). The PMU is responsible for the power supply control and monitoring, while the PIC is responsible for the data packet transmission management. The PMU provides a low-voltage power supply to the PIC, so that it can safely control the power supply to the connected device. The PIC also provides status and error feedback, which helps the PMU safely monitor and control the power supply. The PMU also processes the LED status and environmental monitoring, such as temperature, voltage, current, humidity, and smoke.
The DFR0428 can also be used for intelligent energy management. It can detect the power usage of the connected device, and adjust the power usage according to the current needs. This helps reduce energy costs and improve reliability of the system. The module also has the capability to detect any fault in the system, and provide real-time monitoring of the system’s performance.
The DFR0428 is a smart, reliable, and secure PoE access control system. It is suitable for a variety of applications, allowing for secure and efficient communications. The integrated design of the module makes it easy to install and configure, and its reliable monitoring and management capabilities makes it a reliable solution for a wide range of applications.
