Siemens 6DD1660-0BA0 Fiber Optic Coupling Module

Feature & Principle

It is a fiber optic subrack coupling module for Siemens SIMADYN D control system. It realizes point-to-point synchronous communication over optical fiber via L-bus and C-bus, completes real-time data exchange, clock synchronization and alarm interrupt transmission between different racks. Optical transmission effectively suppresses electromagnetic interference in heavy industrial sites. The module carries 128KB onboard RAM for data buffering. This product is discontinued and applied as maintenance replacement spare for legacy drive and power control racks.
