A new industrial optical data transmission system will operate over distances up to 200m and supports Profibus, Interbus and, soon, DeviceNet and FIP Modbus
The latest addition to Leuze Mayser's range of optical data transmission systems is claimed to be a world-beater in terms of range, transmission rates and system interface capability.
Core application areas that will benefit include automated storage systems and long production lines where information needs to be exchanged exceptional fast and reliably.
Known as the DDLS 200, the new data transmission system has an impressive 200m range with exceptionally fast data transfer rates up to 2Mbits/s.
A patented feature of the new design enables a single person to install and align the units, hitherto not practical with other designs.
Optical data transmission systems are wireless infra-red devices that enable data to be transmitted quickly and reliably between two points, typical applications being the transfer of data to and from stacker-cranes operating in automated storage and retrieval (ASR) applications.
One of the most significant benefits afforded by these devices over alternative systems such as catenary or bus bar systems is that they negate problems associated with wear and tear caused by continual crane travel, thus eliminating downtime and costly repairs.
The new serial DDLS 200 from Leuze Mayser is designed to operate over distances up to 200m, a major benefit being its small physical size.
The housing is approximately two thirds smaller than other comparable units, making installation of the new unit much easier where space is at a premium.
Initially Leuze Mayser is unveiling the new DDLS 200 to support bus systems such as: Profibus up to 1.5 Mbits/s with protocol of FMDS, DP and MPII, Interbus at 2Mbits/s and Allen Bradley DH+ and RIO, with other interfaces such as DeviceNet and FIP modbus to be announced shortly.
The data transmission system is very simple to mount, an integrated spring adjustment mounting plate and a bar graph display making the alignment extremely easy.
The most notable benefits of this design are that units can be mounted and adjusted by a single person.
The method to align the data light barrier from one side only is patented, all operating and connection elements are positioned at the front for easy access.
Leuze Mayser has long been associated with the concept and practicalities of transmitting data using optical devices, over the years it has honed its engineering designs to provide extremely reliable, high-speed systems.
This is reflected in the DDLS 200, a new addition with a performance that cannot be bettered.
