Reliable Signal TransmissionHirschmann Electronics, Inc. Germantown, Maryland has recently added the fiber-optic modem OZD Modbus Plus G12 to its line of Industrial products. This modem, which has been specially designed for use in industrial environments, permits high-speed and high-availability fiber-optic data networks for the transmission protocol Modbus Plus. The devices can be used wherever the reliability of the components is an especially important factor, e.g. in automotive production or process management at industrial plants.The modem has a robust and compact metal housing which provides effective protection against electromagnetic interference fields. A total of three ports are available – one for twisted-pair cables and two for fiber-optic cables. The transmission rate is 1 Mbit/s with a maximum transmission distance of 2,500 meters.The devices can be used in a redundant ring structure and in conventional line and star cable installations. In a ring structure, the HIPER Ring concept (Hirschmann Performance Redundancy Ring) ensures that, in the event of a cable break, the network is automatically reconfigured within less than 500 milliseconds. The modems can be either clipped onto mounting rails or attached using screws. The operating parameters can be read on clearly visible LED indicators. An integrated signaling contact also provides the possibility of remote diagnosis. These two features make both set-up and maintenance of the devices much easier.The Hirschmann Electronics Group stands for competence and power of innovation in the fields of automation and network technology, construction machinery electronics, multimedia communication and automotive electronics.
