Chapter 1 Overview

1.1 Introduction

Aside from 16 x 10/100Base-TX fast Ethernet port, the long MTBF (Mean Time

Between Failures) ensures that the EKI-7526I is a cost-effective solution and meets the

high reliability requirements demanded by industrial applications.

1.1.1 High-Speed Transmissions

The EKI-7526I 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-7526I 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-7526I is extremely compact (79 x 152 x 105 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-7526I supports up to 3,000 V

EFT protection for power line, and also supports

4,000V

ESD protection for Ethernet ports. With these 2 strong protections, it can

secure equipment against unregulated voltage and make systems safer and more

reliable. Further, EKI-7526I 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-7526I is between -40 ~ 75 ℃. With such a wide

range, you can use the EKI-7526I 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.
