R-IL PB BK DI8 DO4/CN-PAC
R-IL PROFIBUS Bus Couplers
The Bosch Rexroth Indramat R-IL PB BK DI8 DO4/CN-PAC is a robust module in the R-IL PROFIBUS Bus Couplers series designed for seamless industrial automation. This device operates on a 24 V DC power supply and offers 8 digital inputs and 4 digital outputs for flexible logic control. As a PROFIBUS DP bus coupler, its primary application is to bridge fieldbus communication and I/O signals, enabling precise data exchange between a control system and distributed I/O modules.
Featuring a D-sub 9-pin socket for PROFIBUS DP connectivity and an IP20 degree of protection, the R-IL PB BK DI8 DO4/CN-PAC supports up to 63 local bus nodes (including two onboard coupler nodes). It automatically detects transmission speeds ranging from 9.6 kBit/s to 12 MBit/s to adapt to diverse network requirements. Input voltage thresholds are defined as –30 to 5 V DC for logical “0” and 15 to 30 V DC for logical “1,” while each output channel delivers up to 500 mA of current. This precise signal handling ensures reliable performance under varying load conditions.
Engineered for demanding environments, the module operates across a temperature span of –25 °C to +55 °C and humidity levels from 5 % to 90 % (non-condensing). At just 80 x 120 x 71.5 mm and 320 g, it facilitates compact panel installations with standardized grounding procedures. Clear channel labeling and on-board Diagnostic LEDs provide immediate status feedback, simplifying commissioning and troubleshooting. Fully compliant with PROFIBUS DP fieldbus standards, this bus coupler enhances system compatibility, durability, and operational efficiency in industrial applications.
