Industrial 90W 4PPoE Injector

The TRENDnet TI-IG90 is a hardened Gigabit PoE injector built for industrial deployments. It delivers up to 90W of 4PPoE power alongside data to compatible devices such as wireless access points, IP cameras or VoIP phones. The unit operates reliably across a -40 to 75 °C temperature range and carries an IP30 rating for dust protection. It is designed for integrators and network engineers who need robust power injection in harsh environments.

Standards and distance limits

The injector complies with IEEE 802.3, 802.3u, 802.3ab, 802.3af, 802.3at and 802.3bt standards, supporting PoE, PoE+ and 4PPoE power classes. Data and power can reach a powered device up to 100m away over standard copper cabling. The DC input accepts 52 to 56 V from an external supply, with a maximum PoE consumption of 72W. Redundant power inputs provide overload current protection for continuous operation.

Mounting and power setup

A DIN-rail clip and wall-mount brackets are included, and a grounding point is provided for safe installation in cabinets or enclosures. The 4-pin removable terminal block simplifies wiring the DC supply, though the compatible TI-S12048 power supply must be purchased separately. LED indicators show link and power status for quick verification. Installers should ensure the source voltage stays within the 52 to 56 V window to avoid startup issues.

Questions about this item

Should I pick the 15.4 W, 30 W or 90 W PoE mode for my device?

The injector auto-negotiates the class; it delivers up to 90 W over four pairs for 802.3bt devices, 30 W for 802.3at gear and 15.4 W for 802.3af equipment.

What does the 90 W headline mean once the unit is installed in a cabinet?

It supplies a full 90 W to a compatible powered device at up to 100 m while the injector itself draws a maximum of 72 W from the 52–56 V DC source.

Which Ethernet standard caps the data rate on the 4PPoE port?

The port complies with IEEE 802.3ab, so Gigabit speed is the practical limit regardless of the PoE class negotiated.
