S908 Remote I/O(RIO) Fiber Optic Converter
Description:
S908 RIO Fiber Optic Converters are designed to be used in Modicon field bus optical repeater. They enable electrical Remote I/O interfaces to be converted into optical interfaces.
Electrical connection to the Remote I/O network is through an “F”–style connector and external Modicon Remote I/O 14 db tap.
By profiting from the familiar advantages of optical transmission technology, the modules can be integrated into existing Remote I/O bus networks. A complete S908 Remote I/O field bus network with modules in point to point, line, star or ring topology, and an arbitrary combination of these, can also be built up.
The redundant ring is also supported, thereby increasing the fail-safety of the field bus network.
The device is powered by 24V DC voltage. A redundant feed increases operational safety.
