Product Description:

The R-IL PB BK DI8 DO4/CN-PAC Bus Coupler functions as an industrial connection device from Bosch Rexroth. The device simplifies general PROFIBUS DP communication to execute control operations.  In industrial automation. The device has a rectangular shape of 80 by 120 by 71.5 mm size and weighs 320 g. IP20 protection category works for controlled industrial settings.

The R-IL PB BK DI8 DO4/CN-PAC bus coupler functions using a power supply of 24 V DC. A D-sub 9-pin interface enables the device to link with PROFIBUS DP networking systems. This device contains a digital control system that combines eight input devices and four output devices. Its users can integrate a maximum of 63 nodes along with the two coupler-mounted nodes. This device functions in a temperature range of -25°C to +55°C alongside a humidity reach of 90%. Users can set '0' signals between -30 to 5 V DC through the device input range. The R-IL PB BK DI8 DO4/CN-PAC bus coupler uses 15 to 30 V DC electrical strength to identify '1' signals. The output channels provide current limits that reach 500 mA. The device automatically detects up to 12 MBit/s transmission speeds alongside 9.6 kBit/s. The design structure enables data transmission between different operational speed levels.

The R-IL PB BK DI8 DO4/CN-PAC bus coupler achieves simple wiring needs because input and output channels have clear labels. Real-time monitoring of signals and power levels is possible for users through this system. During operation Diagnostic LEDs exhibit rapid status indications to users. These visible indicators make the process of detecting errors easier. This bus coupler requires standard panel installation processes which also incorporate grounding procedures. The product features a construction system that operates in demanding conditions over its specified temperature range.
