Dutec I/O Plexer Repeater, Manual

Introduction 1
1 - 2
I/O Plexer Repeaters can be used to convert signals from one type to another. For example, a
thermocouple at the remote site can be converted to a standard process current (4-20mA)
signal at the local site.
Communications:
DuTec supports several standards for transmitting serialized I/O data between I/O Plexer
repeaters. In addition to hard wiring, built in modem control lines allow the use of telephone,
fiber optic, and radio modems at baud rates to 38,400.

RS-422 5,000 1,524
RS-485 5,000 1,524
Modem Unlimited Unlimited
Response Time :
Under full load (sixteen analog and 48 digital signals), the average response time between an
input event and resulting output is less than 250mS @9600 Baud.
Easy Setup:
The I/O Plexer Repeater has its own power supply, no need to purchase or reserve space for
an external supply. A push-button and on board LED indicator configure the baud rate and
Input/ Output separators. Removable terminal strips allow the attachment/ removal of
multiple cable sets in one step. This modularity greatly reduces troubleshooting and upgrade
delays.
