R-IL ETH BK DI8 DO4 2TX-PAC

The Bosch Rexroth Indramat R-IL ETH BK DI8 DO4 2TX-PAC from the R-IL PROFIBUS Bus Couplers series is a high-performance bus coupler designed for advanced industrial automation applications. This bus coupler features eight digital inputs (24 V DC) and four digital outputs (24 V DC), supporting precise signal interfacing at a power supply rating of 24 V DC with a maximum supply current of 0.8 A. Equipped with two Ethernet ports offering 10 Mbps and 100 Mbps transmission speeds, it seamlessly links Modbus/TCP (UDP) networks to Inline I/O devices. The device supports a maximum I/O data capacity of 512 bytes and can address up to 63 devices per station, including the bus coupler itself. Encased in an IP20 degree of protection housing measuring 80 mm x 120 mm x 72 mm and weighing 375 g, it strikes an optimal balance between compactness and robustness.

Performance is optimized through built-in switching functionality and automatic negotiation of link speed and cross-linking, ensuring reliable connectivity at both 10 Mbps and 100 Mbps. The coupler implements an automatic detection mechanism for local bus transmission speed, configurable to 500 kbps or 2 Mbps, allowing flexible integration with diverse Inline devices. OPC server–based data exchange is enabled via native TCP/IP software interfaces adhering to the Device Driver Interface (DDI) and High-Level Language Fieldbus Interface (HFI) standards. With support for up to 16 PCP devices and 61 Inline modules, it delivers scalable I/O expansion for complex system architectures. Local web-based networking options facilitate setup, diagnostics, and monitoring without specialized tools.

Engineered to perform reliably under challenging environmental conditions, this bus coupler operates from -25°C to +55°C ambient temperature and withstands 10% to 95% relative humidity per EN 61131-2 guidelines. It endures storage temperatures from -25°C to +85°C and air pressures ranging from 70 kPa to 106 kPa, supporting installations at elevations up to 3000 m. Certified to Protection Class 3 (EN 61131-2), it integrates seamlessly into industrial control cabinets and automation racks. The R-IL ETH BK DI8 DO4 2TX-PAC’s combination of rugged design, flexible network interfaces, and extensive I/O capacity makes it ideal for factory automation, process control, and motion control applications where reliability and scalability are paramount.
