R-IB IL 24 DI 16-NPN-PAC

The Bosch Rexroth Indramat R-IB IL 24 DI 16-NPN-PAC is a robust member of the R-IB Interface Modules series designed to streamline digital signal acquisition in industrial automation. Manufactured by Bosch Rexroth Indramat, this module features 16 digital inputs with a nominal input voltage of 24 V DC and operates on a 7.5 V logic voltage to ensure precise signal processing. With a compact footprint of 48.8×120×71.5 mm and an IP20 rating, it delivers reliable performance in control cabinet environments. The unit’s lightweight construction (≤122 g) facilitates fast mounting and hassle-free wiring in confined spaces. Its Protection class Class 3 certification under VDE 0106 and IEC 60536 underlines its compliance with stringent safety standards.

Engineered for high-speed data handling, the R-IB IL 24 DI 16-NPN-PAC supports an operating mode of process data, 16-bit resolution over a transmission speed of 500 kbaud. It accommodates sensor connections via 2/3/4-wire circuits and tolerates a broad permissible voltage range of –30 to +30 V DC without performance degradation. Each channel draws a minimal input current of 3 mA per channel, while the local bus consumes ≤60 mA and the module’s overall supply current remains ≤4.0 A. Signal integrity is fortified by clear switching thresholds (high >15 V / low <5 V) that reduce noise susceptibility and ensure accurate state recognition in demanding environments.

Operational resilience is guaranteed by an extensive operating temperature range of –25 to +55 °C and a storage temperature range of –25 to +85 °C, allowing the unit to withstand temperature fluctuations typical in manufacturing and processing plants. The IP20 degree of protection shields internal components from accidental contact and solid particulates, fostering enduring service life. Its solid-state design eliminates moving parts, reducing maintenance requirements and downtime. Furthermore, the module’s precise logic voltage regulation minimizes voltage drift and enhances system stability under variable load conditions.

Integration of the R-IB IL 24 DI 16-NPN-PAC into existing automation platforms is seamless, thanks to its standardized bus connector interface and Bosch Rexroth Indramat compatibility. The module’s compact dimensions and low power consumption make it an ideal choice for distributed I/O architectures in packaging machines, conveyor systems, robotic workcells, and process control stations. By leveraging its advanced digital input capabilities and robust protection features, engineers can expand system functionality while maintaining high availability and simplified diagnostics. Its professional-grade design ensures that critical sensor signals are captured reliably for superior machine performance and long-term operational efficiency.
