Overview
Industio CI-134 Series
4 Ports RS-422/485 Industrial Communication Board
The Industio CI-134 series is designed for RS-422/485
industrial communication. It supports 4 independent RS-
422/485 ports which can control up to 128 devices in a
multidrop environment.
To ease the 2-wire RS-485 half-duplex control, an
Automatic Data Direction Control intelligence is built on
each CI-134 board, eliminating the need of software
interference. Hence, the Windows applications can
manage the RS-485 port without extra code to control the
half-duplex protocol.
To meet the demand of high reliability in industrial
environment, an optical isolation option (2KV) and surge
protection (25KV ESD) are also available in this series.
