DS-EIPE0000-BA0 EIPE SHEET data CTRLink ® PoE Mid-span Injector 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. Typically the injector is inserted mid-span between a standard Ethernet switch and the PD. The EIPE-1 operates from 24 VAC/VDC to produce the required 48 VDC which it injects into the Ethernet cable to provide power and data to the PD. PoE Mid-span Splitter Under certain circumstances a non-PoE compliant device can work with the use of the EIPE-2 splitter. If the end device is 10/100 Mbps Ethernet-based but requires 24 VDC to operate, the splitter will accept the combined 48 VDC and data from a power sourcing equipment (PSE) and then generate 24 VDC to provide the end device with separate data and power.

The upper connector attaches to the upstream device. The lower one attaches to the end device. Transmit and receive signals pass between the two connectors as if the mid-span device were not present. Both mid-span models support the 802.3af protocol. Each has a rugged metal enclosure and metal DIN-rail clip for control panel mounting. The EIPE-1 Injector is powered from a 24 VAC/VDC source — eliminating the need and expense of the 48 VDC power supply typically associated with PoE equipment. In many industrial control systems 24 VDC is readily available in the control panel, just like 24 VAC is available in a BAS system. Using its received power, the EIPE-1 internally generates the 48 VDC PoE power for the Powered Device (PD) — eliminating grounded primary power concerns. With the EIPE-1 powered up, an Ethernet cable is attached to the PD. No power is delivered to the PD until a valid 25 kΩ resistance, called the signature, is sensed by the EIPE-1. Once this value is sensed, the EIPE-1 applies power to the unused pairs and thereby powers the PD. Even if the total cable length is 100 m, the PD receives a minimum of 12.95 watts at its power pins. The EIPE-2 Splitter is powered by 48 VDC which it uses to internally generate the 24 VDC power for the non-PoE device and eliminate any concerns about grounded primary power. The maximum output power is 10 watts.
