OKW has enhanced the versatility of its RAILTEC B and RAILTEC C DIN rail enclosures with the addition of a bus system for energy and data transmission via standardised top-hat rails. The system consists of a bus printed circuit board, the support profile, 1x battery clip block, a rail cover and 2 protective end caps. The latter are for securely fixing the support profile in the DIN rail and for protecting the bus ends.

The support profile for the RAILTEC-BUS system is geared to match standard top-hat rails with a height of 7,5 mm and is available in the two lengths of 250 mm and 500 mm. The assembly process is simple and fast: the bus printed circuit board is inserted in the support profile and then in the standardised rail.

A stable and secure connection between the bus PCB and the device is established by means of the battery clip block with gold-plated double contacts, which is mounted on a separate PCB inside the enclosure. Mechanical processing of the bottom part of the enclosure is necessary for installation. The rail cover is for protecting the printed conductors and can be individually shortened as required, for example when several enclosures are used on the DIN rail.

An advantage of the RAILTEC-BUS system is that hard wiring of the devices is not necessary, which is particularly beneficial in case of service or repair. The battery clip block can also be machine-soldered. The maximum current load is up to 5 A per bus conductor and the maximum voltage 63 V. The system operates reliably at ambient temperatures up to 70°C.
