Overview

Introduction

Many important devices used in today’s industrial environment use

the RS-422 or RS-485 interface for data transmission. In some cases

however, it is necessary to extend the transmission distance between

RS-422/485 devices. This is where the TCC-120/120I RS-422/485

Repeaters come in. Simply wire the power terminal block, wire the

two signal terminal blocks, set the DIP switches, and you’re ready to

go.

The RS-422/485 standards use a differential signal for transmitting

data signals. In addition to distance and multi-drop issues for

industrial applications, housing, wiring, power supply, and over-surge

protection are also serious concerns.

The TCC-120I provides isolation protection for users who need an

industrial grade repeater to extend RS-422/485 transmission distance

and increase networking capability. The superior industrial application

design of this product, which includes DIN-Rail mounting, terminal

block wiring, external terminal block power, and optical isolation for

system protection, makes the TCC-120/120I suitable for use in critical

industrial environments.
