PEM3024C 概述
A PoE powered-device module is a type of power extraction and conversion module within the power-over-Ethernet hierarchy: IEEE 802.3at PoE+ system -> powered device (PD) interface -> DC-DC power module -> end equipment. Its role is to perform PD detection, classification, inrush current limiting, and isolation, presenting a regulated DC rail to the host system without any local AC power input.
Key features of the PEM3024C include complete IEEE 802.3at compliance for 30W Class 4 power delivery, operation from both PoE+ (802.3at) and PoE (802.3af) PSE sources, a 24V DC output rail suitable for industrial and telemetry electronics, and a 14-pin module footprint that simplifies integration compared to discrete PD controller plus transformer designs.
Technically, the module integrates the PD interface physical layer, including the detection and classification signature required by the IEEE 802.3at standard, together with an isolated flyback-style conversion stage that delivers a regulated 24V output at up to 30W. This integration reduces design time and BOM count for Ethernet-powered end nodes.
Typical applications cited by distributors include home automation, remote sensors, security and surveillance equipment, telemetry systems, and wireless connectivity nodes - all scenarios where running power over the existing Ethernet drop is more economical than local mains wiring.
A key design consideration is thermal management: at full 30W extraction, the module dissipates heat through its PCB mounting, so adequate copper area and airflow around the module are recommended. Verify input cabling is genuine CAT5 or better to minimize DC resistance losses on the power pairs.
This page synthesizes distributor availability data, compliance notes, and practical application guidance not found in a single datasheet, providing engineers with consolidated selection information for the PEM3024C PoE+ PD module.

典型应用
PEM3024C 适用于 6 应用s: IP Security and Surveillance Cameras, Wireless Access Points and Connectivity Nodes, Remote Sensors and Telemetry, Home Automation Controllers, Industrial Ethernet Edge Devices, VoIP and Intercom Endpoints.
IP Security and Surveillance Cameras
Security equipment is a distributor-listed target application for the PEM3024C. A 30W, 24V PoE+ output covers the power budget of fixed IP cameras, PTZ domes, and models with IR illuminators or heater blowers, which frequently exceed the 12.95W ceiling of legacy 802.3af. In a typical design, the camera Ethernet jack connects to the module input, and the camera main board runs directly from the regulated 24V rail or a downstream point-of-load converter. Because the module implements the IEEE 802.3at detection, classification, and inrush signature, the camera designer avoids discrete PD controller layout and compliance testing at the interface level, reducing both BOM count and certification risk for the powered-device port.

Wireless Access Points and Connectivity Nodes
Wireless Connectivity is explicitly listed as a PEM3024C application. Ceiling- and wall-mounted Wi-Fi access points and small-cell radios are almost always installed where Ethernet exists but mains power does not, making PoE+ the natural power delivery method. The 30W budget supports multi-radio 802.11ac/ax access points, which typically draw 15-25W under load. The 24V regulated output feeds the AP's main DC-DC stage, which in turn generates the RF chipset rails. Because the PEM3024C accepts both IEEE 802.3at and 802.3af sources, the same hardware can be deployed on legacy PoE switches at reduced power classes and on PoE+ infrastructure at full 30W capability, simplifying product SKUs across customer sites.
推荐
Remote Sensors and Telemetry
Remote sensors and telemetry equipment are distributor-listed applications for the PEM3024C. Industrial telemetry nodes - flow meters, tank-level transmitters, weather stations, and utility monitoring points - often sit far from any mains outlet but already have Ethernet runs for data backhaul. The module extracts up to 30W at 24V from that cable, powering the sensor, its microcontroller, and a local radio or cellular modem. Operating from both PoE+ and PoE sources means integrators can deploy over existing 802.3af switches today and upgrade to PoE+ later without hardware changes. The regulated 24V output also matches common industrial sensor supply conventions, minimizing the need for additional conversion stages at the node.
推荐
Home Automation Controllers
Home Automation is listed as a primary application for the PEM3024C in distributor data. Smart-home hubs, door-station controllers, multi-room audio zones, and automation panels frequently combine an Ethernet uplink with moderate power demands of 10-25W. A PoE+ PD module lets these products ship without an external wall adapter: the installer runs a single CAT5 cable for both data and power. The 24V output can directly drive actuator and relay rails common in automation hardware, while downstream buck converters supply 5V and 3.3V logic. Because the module is backward compatible with IEEE 802.3af, devices remain functional even when connected to older residential PoE equipment, improving field flexibility and reducing support burden for installers.
推荐
Industrial Ethernet Edge Devices
Industrial automation nodes - remote I/O blocks, edge gateways, and machine-monitoring probes - increasingly standardize on PoE to consolidate cabling. The PEM3024C's 24V output aligns with industrial control conventions, allowing direct feed of relay coils, indicator circuits, and 24V-rated sensor interfaces. At 30W from an IEEE 802.3at source, the module supports edge gateways with embedded processors and multiple field interfaces. Its 14-pin board-mount footprint integrates into standard industrial PCB assemblies, and RoHS compliance (No SVHC as of 27-Jun-2018) supports European market deployment. Designers should confirm the isolation specification from the official Infomart datasheet when the module bridges a grounded industrial Ethernet infrastructure and floating field-side circuitry.
推荐
VoIP and Intercom Endpoints
Ethernet-connected voice and intercom endpoints, including IP phones, door entry panels, and emergency call stations, are classic PoE powered devices and fall within the PEM3024C's application set of security and telemetry equipment. Typical VoIP handsets draw 5-13W (802.3af class), while video door stations with displays, cameras, and lock-control relays can require up to 25-30W, exactly matching the module's PoE+ rating. The regulated 24V output feeds downstream point-of-load converters for the DSP, display, and amplifier stages. Using a certified PD module removes the burden of implementing IEEE 802.3at detection and classification discretely, accelerating time to market for endpoint manufacturers who must interoperate with a wide range of PoE switches.

关键差异点
- Integrated IEEE 802.3at-compliant PD interface （对比 Discrete PD controller + separate DC-DC design)

- Industrial-friendly 24V output rail （对比 Typical 12V-output PD modules)
设计说明
At full IEEE 802.3at power extraction, the PEM3024C passes up to 30W to the load, and its internal conversion stage dissipates the difference between input and output power as heat within the module. Provide generous PCB copper area connected to the module's ground and thermal pins, and consider airflow if the end product is enclosed. Estimated: if module efficiency is around 85% (typical for isolated PoE PD converters - confirm from the official datasheet), a 30W output implies roughly 5.3W of internal dissipation, which is significant in sealed enclosures and must be validated by thermal measurement.
Use the official PEM3024C-3 footprint from Component Search Engine rather than redrawing the 14-pin land pattern by hand; the published footprint includes recommended courtyard and keep-out dimensions. Keep the Ethernet magnetics-to-module path short and respect any creepage/clearance guidance in the Infomart datasheet, since the module bridges the Ethernet cable power domain and your system logic domain. Route the 24V output with adequate trace width for the load current - at 30W and 24V that is approximately 1.25A continuous, so 20-mil (0.5 mm) or wider traces with 1 oz copper are a sensible minimum.
Two pitfalls recur in PoE PD designs. First, do not assume full 30W operation on legacy networks: when the PSE is IEEE 802.3af rather than 802.3at, the available power is capped at the 802.3af class budget, so design downstream load shedding or brownout behavior accordingly. Second, cabling quality directly affects input voltage: long or counterfeit CAT5 runs add series resistance on the power pairs, starving the module during PSE inrush and startup. Always verify the isolation rating and operating temperature range in the official Infomart datasheet before finalizing an industrial or outdoor design - these values are not published in distributor summary listings.
