Hollysys Industrial Optical Bus Control System Ocs

Industrial Intelligent Data Transmission Unit (iDTU) replaces traditional junction boxes and integrates multiple control functions into one unit.
·  Miniaturization: An iDTU as big as two A4 papers in size
·  All in One: Enclosure adopting integrated aluminum die-casting process
·  Visualization: Operating status displayed without opening the enclosure
·  User-Friendly: Design Handle design on the side

Industrial Optical Bus Redundant Junction Unit (RJU) is used to collect signals from iDTUs, and then signals are remotely transmitted to controllers via the main optical fiber.
·  Power supply not required, and meeting explosion-proof standards
·  Adopting physical optical splitting technology, no protocol conversion and delay, and safe and reliable operation
·  Optical components contributing to a longer lifespan compared with switches, MTBF time close to infinity
·  Support for distribution of 1 optical fiber to 16/32 channels
·  Suitable in Zone 2 hazardous area

Onet (Onet Industrial Optical Bus) is used to achieve remote communication between control equipment such as iDTU and RJU, and controllers.
·  High Efficiency: 2 copper wires required by an instrument signal in traditional control systems, and only a pair of redundant optical fibers needed for 512 instrument signals in Onet which boasts high bandwidth and robust real-time communication
·  High Quality: Optical fiber transmission which features strong real-time performance, anti-electromagnetic interference, and common mode interference and offers higher and more stable transmission rates compared with traditional communication methods
·  High Reliability: Redundant star network topology, which ensures safe and reliable transmission, distributed faults, and flexible expansion, and Onet conforming to the international standard IEC61158, national standard JB/T 10308.3-2001, and European standard EN50170
