### 4. Functionality

The TSPL-101GT-M12-24V functions as a PoE power splitter, separating power and data from a single Ethernet cable. It receives power and data through a PoE-enabled Ethernet connection and outputs regulated 24V DC power for non-PoE devices while maintaining data connectivity.

Operational Principle:
1. The splitter connects to a PoE injector or PoE switch via an M12 Ethernet connector.
2. It detects the PoE signal according to IEEE 802.3af/at standards.
3. Once a valid PoE signature is detected, it draws power from the Ethernet line.
4. The internal DC-DC converter regulates the voltage to 24V DC output.
5. The data signal is passed through to the connected device without interference.

Use Cases and Applications:
- Railway and rolling stock communication systems
- Vehicle-mounted network devices
- Industrial automation and control systems
- IP surveillance cameras and sensors requiring 24V DC
- Transportation and logistics monitoring systems
- Harsh-environment networking where M12 connectors are required

Compatibility:
- Compatible with IEEE 802.3af (PoE) and IEEE 802.3at (PoE+) power sourcing equipment.
- Works with standard Ethernet devices such as switches, routers, IP cameras, and controllers.
