Power over Ethernet (PoE) equipment adds power to the data in Ethernet wiring — so that devices such as surveillance and card access machines can be powered via standard Ethernet cabling. PoE applications require a 48 VDC power source, but most automation systems run from 24 VAC/VDC power. If only one Ethernet-powered device (PD) needs power, the EIPE-1 can provide it. Under certain circumstances a non-PoE compliant device can work with the use of the EIPE-2 splitter.
The EISK8P-GT gigabit switch within the Skorpion Series is an 8-port unmanaged Ethernet switch with Gigabit Ethernet (GigE) performance on all ports and PoE on four ports–supplying 15.4 W per PoE port. GigE jumbo frames up to 9216 bytes are supported for maximum system performance. 10/100 Mbps legacy devices are supported via Auto-Negotiation—accommodating any Ethernet automation system. This low-cost compact unit has a rugged metal enclosure and is intended for DIN-rail mounting in control panels. The unit is powered from 48 VDC and operates over 0 to 60°C temperature range.
The EIDX_MP Series of Ethernet switches provide management functionality in situations where extended temperatures of -40°C to +75°C are expected. Ports 9 through 16 (located on the bottom of the unit) support Power-over-Ethernet (PoE), providing data and power over one cable. The unit acts as power source equipment (PSE) — supplying up to 15.4 W per port for IEEE 802.3af-compliant powered devices (PD).
