Moxa SPL-24-T PoE splitter -40 to 75°C 12.95 W at 24 V DC content_copy

The Moxa SPL-24-T is an industrial PoE splitter that separates power and data transmitted over a single Ethernet cable. It enables the supply of end devices lacking PoE capability with a stable DC voltage of 24 VDC, while simultaneously maintaining data communication over a standard CAT5 cable. The device functions as a Powered Device (PD) and is designed for use with IEEE 802.3af-compliant PoE injectors. The SPL-24-T variant features an extended operating temperature range, suitable for demanding industrial environments.

Applications

The SPL-24-T is suitable for industrial applications requiring reliable power supply and data transmission over existing network infrastructure. Typical use cases include powering sensors, camera surveillance systems, industrial controls, or other devices connected via Ethernet cable but lacking integrated PoE support. Its compact design and mounting on a DIN rail facilitate integration into enclosures and industrial control systems.

Functions and Features in Detail

The device features two RJ45 connectors: one for PoE input (as PD) and one for data output. It supports Auto MDI/MDI-X and Auto-Negotiation, ensuring flexible cabling and automatic speed adaptation (10/100BaseT(X)). Data transmission occurs in full- or half-duplex mode. The integrated overcurrent protection safeguards the device and connected components against damage from short circuits or current surges.

Technology Explained Simply

The SPL-24-T converts the PoE voltage (44 to 75 VDC) transmitted over the Ethernet cable into a constant output voltage of 24 VDC. The maximum output power is 12.95 W, sufficient to power small to medium industrial devices. Power supply is via a removable 3-pole terminal block, enabling flexible and secure connections. The protection rating IP30 provides protection against solid foreign objects and splashing water, but not against dust or prolonged moisture — thus, the device is intended for use in enclosed enclosures.

Compatibility and Accessories

The SPL-24-T is compatible with IEEE 802.3af-compliant PoE injectors that deliver the required power over the network cable. The use of standard CAT5 cables allows for easy integration into existing networks.

Mounting and Installation

Mounting is done via a DIN rail, enabling quick and secure installation in enclosures. Dimensions of 24.9 × 100 × 86.2 mm and a weight of 95 g make the device compact and lightweight. Installation requires no special tools, as connections are made via a terminal block. The included quick start guide supports setup.

Operational Advantages

The SPL-24-T provides reliable power supply for non-PoE-capable devices without requiring additional power lines. The integrated overcurrent protection increases operational safety. The high operating temperature range of -40 to 75 °C makes the device suitable for extreme environmental conditions, such as those found in industrial or outdoor installations. Certifications to UL 60950-1, CISPR 32, FCC Part 15B Class A, and IEC 61000-4-2/3/4/5/6/8 ensure high safety and EMC compliance. The MTBF is 5,104,703 hours according to MIL-HDBK-217F, indicating a long service life. The warranty period is 5 years.

The delivery includes the SPL-24-T device, a quick start guide, a product certificate, and a product note, all in simplified Chinese, as well as a warranty card.
