The AL700 Embedded Blue® is a Single Pair Ethernet (SPE) switch designed for rugged industrial applications. The box is provided with five 100BASE-T1 (IEEE 802.3bw) ports and in addition two 1000BASE-T RJ45 jacks for uplink and port expansion.
The 4-way circular M8 Hybrid SPE connectors are covered by the IEC 63171-6, combining power and data distribution. Any AL700 SPE port can deliver up to 2.3A at voltages up to 57V, individually protected by an eFuse. The M12-A power input connector accepts 9-57VDC. As an option the box can be equipped with a terminal block power connector.

The AL700 is equipped with the Marvell® 88Q5072 Automotive Ethernet switch and is configured by default for self-managed operation. Its PHYs are fully inter-operable with the Open Alliance BroadR-Reach® (OABR) standard for automotive connectivity.
The AL700 box is available for DIN rail or wall mount. Switch port expansion can be easily achieved by means of RJ45 Ethernet patch cables, connecting two or more AL700 together. As AL710, the switch box is also available with a mezzanine CPU card (AC370) for additional protocol support such as AVB/TSN, and Wi-Fi 6 wireless communication.
