Moxa TCC-120I [6/18] Overview

Overview

Introduction

Many important devices used in today’s industrial environments 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 wall 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.
