1.1 Introduction

The EKI-2525/2525I/2528/2528I is a cost-effective solution and meets the high
reliability requirements demanded by industrial applications.
1.1.1

High-Speed Transmissions

The EKI-2525/2528 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

Dual Power Input

EKI-2525/2525I/2528/2528I 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.
1.1.3

Flexible Mounting

EKI-2525/2525I/2528/2528I is extremely compact (37 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.
1.1.4

Advanced Protection

EKI-2525/2525I/2528/2528I supports up to 3,000 VDC surge protection for power line,
and also supports 4000V 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-2525/2525I/2528/2528I provides currency overload protection
with a resettable fuse to ensure that the device component won't be damaged by
overload current.
1.1.5

Wide Operating Temperature

The operating temperature of the EKI-2525/2528 is between -10 ~ 60 ℃ and the EKI-
2525I/2528I is between -40 ~ 75 ℃. With such a wide range, you can use the EKI-
2525/2525I/2528/2528I in some of the harshest industrial environments that exist.
1.1.6

Easy Troubleshooting

LED indicators make troubleshooting quick and easy. Each 10/100 Base-TX port has 2
LEDs that display the link status, transmission speed and collision status. Also the
three power indicators P1, P2 and P-Fail help you diagnose immediately.
