A 24V POE (Power over Ethernet) splitter is a specialized device that separates power and data signals transmitted over a single Ethernet cable, delivering 24V DC power to low-voltage network devices while forwarding Ethernet data to a connected device. Unlike standard POE injectors (which add power to Ethernet cables), POE splitters “split” the combined power-data signal, making them essential for powering devices that do not natively support POE (e.g., IP cameras, wireless access points, or small network switches) and require 24V power—higher than the 12V or 5V output of most standard POE splitters.

The core functionality of a 24V POE splitter revolves around its ability to handle both power and data over Cat5e/Cat6 Ethernet cables, complying with POE standards such as IEEE 802.3af (15.4W max power) or IEEE 802.3at (30W max power, also called POE+). The splitter receives a combined signal from a POE-enabled switch or injector via the Ethernet cable’s unused pairs (pins 4/5 and 7/8 for af/at) or common-mode power over all pairs. Internally, a rectifier converts the incoming AC-like POE power to DC, and a voltage regulator steps it down (or up, in some cases) to a stable 24V DC. Meanwhile, the data signals (transmitted over pins 1/2 and 3/6) are filtered and forwarded to the device’s Ethernet port without interference. This separation ensures that data transmission speeds (up to 1 Gbps for Gigabit Ethernet) remain unaffected by power delivery, maintaining network performance.

24V POE splitters are widely used in security and surveillance systems, where IP cameras often require 24V power for infrared (IR) night vision or pan-tilt-zoom (PTZ) functionality. For example, a 4MP IP PTZ camera may need 24V/2A power to operate its motors and IR LEDs; a 24V POE splitter can draw 30W power from a POE+ switch, split it into 24V DC for the camera, and send Ethernet data back to the NVR (Network Video Recorder) for recording. This eliminates the need for separate power cables, reducing installation costs and complexity—especially in hard-to-reach areas like ceilings, walls, or outdoor locations where power outlets are scarce.

Another key application is industrial automation, where 24V is the standard power voltage for many sensors, controllers, and small actuators. A 24V POE splitter can power these devices while connecting them to the industrial Ethernet network, enabling real-time data monitoring and control. For instance, in a manufacturing plant, a temperature sensor with an Ethernet port can be powered by a 24V POE splitter, sending temperature data to a central SCADA (Supervisory Control and Data Acquisition) system via the same cable that delivers power. This simplifies wiring in harsh industrial environments and reduces the risk of power-related downtime.

Key features to consider when selecting a 24V POE splitter include power output capacity (e.g., 24V/1A, 24V/2A, or 24V/3A, matching the device’s power requirements), POE standard compliance (af or at, depending on the required power), data rate support (10/100/1000 Mbps), and environmental ruggedness (IP65/IP67 ratings for outdoor or dusty applications). Many models also include overcurrent, overvoltage, and short-circuit protection to safeguard connected devices from power surges—a critical feature in industrial or outdoor settings where electrical fluctuations are common.
