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.
