1 <<Contents>> <<ndex>> General pecifications G 3QL7-3 odels, ptical us Repeater odule (for ultimode Fiber) GRAL ptical us Repeater odule converts us signal into optical signal, where the bus connects a safety control unit (C or C ) and a safety node unit (D). An us transmission distance can be extended by connecting an ptical us Repeater aster odule () and an ptical us Repeater lave odule () with a multimode optical fiber cable. hese modules enable the bus to be extended by utilizing the existing multimode fiber cables when replacing the existing systems (roafe-lc etc.). ptical us Repeater aster odule his module is connected from us Coupler odule (C, C) on the safety control unit or us nterface odule () on the safety node unit (D) through us cable. here are two types of us Repeater odules: with or without a terminator. ptical us Repeater lave odule his module is connected from ptical us Repeater aster odule through fiber-optic cable. Furthermore, it is connected through us cable to us nterface odule () on the safety node unit (D).

When the reference dimension is over mm, its nominal tolerance is in accordance with J 9. RRC AD CA FR G A pair of ptical us Repeater odules for redundant configuration are mounted on a pair of annexed slots. he us module is always mounted on a slot with odd number and the us module with even number. When / are mounted on D and used at temperature ranges from to 7 C, two slots next to the power supply module must be left open, a pair of s is mounted in annexed slots, and two slots between the two s are left open. An nit for ptical us Repeater odule (D) is a unit to mount ptical us Repeater odules. Refer to nit for ptical us Repeater odule (Rack ountable ype) (G 3QK-3) for more details. For restrictions in mounting C, C and D, conform to the instructions for and described in roafe-r utline of / odules (for F) (G 3K-). RARK FR / must be used with the following C modules. - C unit revision : or later - C / can be used with / in two connecting stages with the maximum total distance of 9 km. / can also be used with / in two connecting stages with the maximum total distance of km. When installing /, conformance to the instructions for and of roafe-r nstallation Guidance ( 3J-) is required. As for engineering of /, conform to the instructions for and of lectronic nstruction anual : CH and RC. All Rights Reserved. Copyright, Yokogawa lectric Corporation G 3QL7-3 ov. 7, -
