Product Description:
The R-IL PB BK DI8 DO4/EFPAC bus coupler from Bosch Rexroth Indramat is built for the demands of industrial automation. That means it can handle digital signal interfacing—and do it reliably. You'll find eight digital input channels, each with standardized electrical parameters—voltage thresholds (like 24V DC nominal) and current specs that ensure you can detect binary states from sensors and switches with confidence. Those inputs can handle high-speed signal acquisition with defined signal delay times that are critical for real-time control. The device also includes four digital output channels, with nominal output parameters (such as switching capacity and load current ratings) to drive actuators, relays and other industrial loads. Those outputs come with overload and short-circuit protection, so you can rely on them in harsh environments. The bus coupler's mechanical design is precision-engineered to fit seamlessly into control cabinets or DIN rail-mounted enclosures. Its housing is designed to withstand dust, moisture and mechanical stress. It operates within defined temperature and humidity ranges, so you can count on it to perform in harsh conditions.
Power supply requirements are clearly specified, including input voltage tolerances (24V DC ±10%) and current consumption details to help you budget system power. Compliance with EMC standards (like IEC 61000) means it can resist industrial noise and limit electromagnetic emissions—so you don't have to worry about interference with adjacent equipment. One of the key features of the R-IL PB BK DI8 DO4/EFPAC is its PROFIBUS-DP interface. That lets you have high-speed, deterministic communication within distributed automation systems. The interface supports standard PROFIBUS protocols, with configurable transmission rates (up to 12 Mbps) and 9-pin D-sub connector integration. The internal local bus architecture manages data exchange between the DI/DO channels and the PROFIBUS network. That means you get defined addressing schemes and data throughput limits to prevent bottlenecks. System constraints like maximum station count per segment and data buffer capacity are documented to ensure you can scale your network correctly.
The device also provides real-time diagnostic capabilities, including status monitoring for inputs, outputs and bus communication. That lets you detect and fix issues before they become significant problems. The digital input and output channels have detailed electrical and timing specifications. Inputs come with noise filtering, reverse polarity protection and ESD safeguards. Outputs feature switching delays and PWM compatibility where applicable. Signal propagation times for both inputs and outputs are specified to ensure synchronization in high-precision control loops. And if there are any issues—like wire breaks, overload conditions or PROFIBUS communication faults—the bus coupler will report them to you. That combination of features, plus conformance to industrial standards, makes the R-IL PB BK DI8 DO4/EFPAC a robust and reliable component for advanced automation systems.
