MURRELEKTRONIK, represented in Australia by Sick Pty Ltd , has released the Profibus DP with IP67 protection. The IP67 housing, the extremely compact design and the encapsulated electronics make the Murrelektronik repeater extremely robust. It is suitable for direct installation in the field. This has advantages when field bus cables are being routed.
The repeater can be integrated directly into the field bus line in accordance with industrial standards using M12 round plug connectors. The number of field bus slaves in the overall system can therefore be increased and the expansion limits of the field bus extended.
Many automated handling systems and robot applications have a modular design. The use of the repeater allows branches to be made in the Profibus cable. The interface between the individual process modules that is created in this way is electrically isolated and meets all Profibus specification requirements. The repeater is extremely easy to use because it automatically adapts to the data transfer speed of the system.
Mostly field bus line signal levels drop as the number of field bus slaves increases within a system. Good signal levels are less susceptible to interference and are therefore a prerequisite for making processes run reliably. The repeater acts as a signal amplifier and therefore provides more operational reliability.
