VAHLE POWERCOM® 485 is the latest development of the well-known VAHLE POWERCOM data communication systems, first introduced in 1984. It was especially designed for RS 485 based industrial data bus systems and operates at a data rate of 19.2 Kbit/s.

With the new generation of electronic components on the world market, the dimensions of the VAHLE POWERCOM® 485 could be substantially reduced and the unit could be housed in a compact top-hat rail housing integrated with the necessary power supply equipment. The compact design simplifies installation and the selection of the installation site, e.g. on electrical overhead monorails.

VAHLE-POWERCOM® 485 has on its front an integrated transparent RS 485 interface in accordance with PROFIBUS, below the power supply 230 V, 50 Hz, or alternatively 115 V, 60 Hz, and the 2-pole connection for the conductor system. Three-status LED inform about the status of the unit.

VAHLE-POWERCOM® 485 provides safe communication for RS 485 industrial data bus systems using VAHLE conductor systems up to 5000 m length, including switches, turntables, lifting stations etc. The data rate is 19.2 Kbit/s with an internal delay of max. 3 bits. It can be used for point-to-point transmission and for bus systems. Number of slaves according to data bus specification.

Tree, ring, and line structures with transfer points, isolating sections, etc. can be realized. VAHLE POWERCOM ® 485 is the ideal communication link for electric overhead monorails, straight and curved AS/RS systems, slipring bodies and other track-guided material handling equipment.
