Overview
1.1 Introduction
The 8 port 10/100TX with 4 Port High-Power PoE Industrial Switch is a cost-effective
solution, which meets the high reliability requirements demanded by industrial
applications, and also supports to operate in the wide temperature -40°C ~ 75°C
environment. Besides, the equipment supports
24V or 48V DC power input
and
provides the
PoE function with 48VDC output
for kinds of Powered Devices to
receive power as well as data over an RJ-45 cable.
1.1.1 High-Speed Transmissions
The EKI-2528PAI includes a switch controller that can automatically sense
transmission speeds (10/100 Mbps). The RJ-45 interface can also be auto-detected,
so MDI or MDI-X is automatically selected and a crossover cable is not required. All
Ethernet ports have memory buffers that support the store-and-forward mechanism.
This assures that data is properly transmitted.
1.1.2 Power-over-Ethernet (PoE)
PoE eliminates the need to run AC power to other devices on a wired LAN. While using
Power-over-Ethernet system, installers need to run only a single Category 5 Ethernet
cable that carries both power and data to each device. This allows greater flexibility in
the locating of network devices and significantly decreasing installation costs in many
cases.
1.1.3 Dual Power Input
EKI-2528PAI redundant power input design is with power reserve protection to prevent
the switch device broken by wrong power wiring. When one of power input is fail, P-
Fail LED will turn on and send an alarm through a relay output for notifying user.
1.1.4 Flexible Mounting
EKI-2528PAI is extremely compact (48.6 x 140 x 95 mm) and can be mounted on a
DIN-rail or a panel, so it is suitable for any space-constrained environment.
1.1.5 Advanced Protection
EKI-2528PAI supports up to 3,000 VDC surge protection for power line, and also
supports 6,000V ESD for Ethernet ports. With these 2 strong protections, it can secure
equipment against unregulated voltage and make systems safer and more reliable.
Further, EKI-2528PAI provides currency overload protection with a resettable fuse to
ensure that the device component won’t be damaged by overload current.
1.1.6 Wide Operating Temperature
The operating temperature of the EKI-2528PAI is between -40 ~ 75
℃
. With such a
wide range, you can use the EKI-2528PAI in some of the harshest industrial
environments that exist.
1.1.7 Easy Troubleshooting
