Introduction; High-Speed Transmissions; Dual Power Input; Flexible Mounting - Advantech EKI-2528 User Manual

Chapter 1 Overview

1.1 Introduction

The EKI-2525/2528 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-2525/2528 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-2525/2528 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-2525/2528 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-2525/2528 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 : . With such a
wide range, you can use the EKI-2525/2528 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.
