Overview; Features - Mitsubishi aj65sbt-rps User Manual

1. OVERVIEW

This User's Manual describes the specifications, part names, settings and
others of the AJ65SBT-RPS type CC-Link system optical repeater module (for
SI/QSI fiber-optic cables) and the AJ65SBT-RPG type CC-Link system optical
repeater module (for GI fiber-optic cables) used in the Control &
Communication Link (hereafter abbreviated to CC-Link).

1.1 Features

The AJ65SBT-RPS/RPG module is used to increase the flexibility of laying the
cables of the CC-Link system.
Using two the same product of AJ65SBT-RPS/RPG enables a transmission
distance increase and T-junction wiring using fiber-optic cables in all CC-Link
systems.
In addition, using fiber-optic cables facilitates avoiding the noise trouble of the
transmission path, improving system stability.
(1) Extended transmission distance in CC-Link system
Use of this module increases the transmission distance of the CC-Link system.
In addition, use of multiple modules enables the transmission distance to be
increased up to 3 stages (up to 2 stages when the AJ65SBT-RPGs are used).

*1 The maximum transmission distance on the assumption that the transmission speed setting is
156kbps in a system only the AJ65SBT-RPSs are used as repeaters.
*2 Though not shown here, the other remote stations can be connected between the repeaters.
(2) Enabled T-junction wiring in CC-Link system
Arrangement of these modules between the CC-Link system modules
enables the CC-Link system to be wired in the form of T-junction.

T-junction wiring enabled!!
(3) Noise-resistant stable system
Fiber-optic cables used for junction and extension make it easy to avoid
trouble caused by noise, improving system stability.
Increased up to 7.8km!!
