IO-4POE PoE PSE Module with IEEE 802.3af/at Output

The IO-4POE is a PoE PSE module designed to provide 48V DC PoE power output through its dedicated PoE headers. It accepts a 12V DC supply through the POE_PWR1 input header and supports IEEE 802.3af and IEEE 802.3at PoE output modes.

For IEEE 802.3af output, the module provides 48V DC at up to 350 mA, with a maximum output power of 15.4W. For IEEE 802.3at PoE+ output, it provides 48V DC at up to 750 mA, with a maximum output power of 30W. POE_PWR1 is a 2 × 4-pin female header with a 2.54 mm pitch and includes 12V, GND, and PCTL signals. Two onboard 2 × 4-pin female headers, POE1 and POE2, provide the documented 48V output signals, MPS_OUT signals, and GND connections; both use a 2.54 mm pitch.

The module measures 80 mm × 30 mm × 18 mm.

Q: Which PoE standards does the IO-4POE module support?
A: The IO-4POE PoE PSE module supports IEEE 802.3af PoE and IEEE 802.3at PoE+ output. The documented output ratings differ between these two supported PoE standards.

Q: What power input does the IO-4POE module require?
A: The module supports a 12V DC power input. Power is supplied through the POE_PWR1 2 × 4-pin female header, which uses a 2.54 mm connector pitch.

Q: What are the documented IEEE 802.3af and IEEE 802.3at output ratings?
A: IEEE 802.3af output is rated at 48V DC, bis zu 350 mA, with a maximum power output of 15.4W. IEEE 802.3at output is rated at 48V DC, bis zu 750 mA, with a maximum power output of 30W.

Q: Which connectors provide the PoE output signals?
A: POE1 and POE2 are two onboard 2 × 4-pin female headers with a 2.54 mm pitch. They provide VOUT_48V, MPS_OUT1/2/3/4, and GND signals.

Q: What control signal is available on the power input header?
A: The POE_PWR1 header includes a PCTL signal in addition to the 12V and GND connections. The current product documentation does not further define the function of PCTL.
