5 Port Industrial Ethernet Switch with 4 PoE Ports
Five 10/100 Base-T Ethernet Ports
Four 802.3af End-point PoE Injector Ports

Wide Operating Temperature (-40 to 75C)
3000V EFT & 6000V ESD Protection
Dual 24 or 48 VDC Power Inputs
The EIRP305-24-T is a five Port Unmanaged Industrial
Ethernet Switch with four 802.3af (Alternative A) end-point Power-
Over-Ethernet ports. As power sourcing equipment (PSE), these
ports can be used to power 802.3af compliant powered devices
(PD). This eliminates the need for a separate power line to each
end device.
High-Speed Transmissions: The EIRP305-24-T includes a
switch controller that automatically senses transmission speed
(10/100 Mbps). The RJ-45 interface also auto-detects MDI or
MDI-X, eliminating the requirement for a crossover cable. Each
port is buffered and supports store-and-forward protocol.
Dual Power Input: To reduce the risk of power failure, the
EIRP305-24-T provides two 24 or 48 VDC power inputs. If the
power fails, the switch will automatically use the secondary power
input. Also, if the power goes out the corresponding P1 or P2
LED will go out and the Fault LED will light. The contacts for the
alarm output will also open.
Flexible Mounting: The switch features a space saving IP30
metal enclosure that can be DIN or Panel mounted.
Transient Protection: The power line input on the EIRP305-24-T
offers protection from up to 3,000 V EFT. The Ethernet ports offer
up to 6,000 V ESD protection. These features make the switch
