R-IB IL 24 DI32/HD-NPN-PAC

The R-IB IL 24 DI32/HD-NPN-PAC from Bosch Rexroth Indramat is a high-density digital interface module in the R-IB Interface Modules series, designed for robust industrial automation environments. This versatile module features 32 digital inputs with an NPN transistor (sourcing) configuration, supporting a 24 V DC supply voltage. Built to withstand demanding control applications, it provides IP20 protection (IEC 60529) and operates with a total load current capacity of 4 A. Its compact design and dense channel layout deliver exceptional signal integrity without compromising installation space.

The module’s technical capabilities include a process data update time of <1.5 ms per channel> and a local bus transmission speed of 500 kbps, ensuring responsive and reliable communication. Each input channel supports a maximum load current per input of 250 mA and extends wiring runs up to 30 m, thanks to optimized internal design. The connection method utilizes three-wire spring-cage terminal connections for secure, tool-free installation, while the digital input reference voltage of 24 V DC maintains compatibility with a wide range of sensors. Integrated short-circuit and overload protection safeguards connected devices and preserves system uptime in overloaded or fault conditions.

Operational features emphasize usability and safety. Green LED status and diagnostics indicators provide clear, real-time feedback on input status and fault conditions, reducing troubleshooting time. The built-in short-circuit & overload protection ensures that individual channel faults do not compromise overall module performance, supporting continuous operation under maximum load conditions. With an IP20 degree of protection rating, the unit excels in enclosed control cabinets and dry, dust-free environments. The tool-free spring-cage terminals simplify maintenance and module replacement while preserving signal integrity across all 32 channels.

Seamless integration into existing automation architectures is straightforward. The R-IB IL 24 DI32/HD-NPN-PAC interfaces natively with Kollmorgen CD Servostar drive systems and other programmable logic controllers via its standardized local bus. Engineers can deploy this module across diverse industrial applications—ranging from factory automation to material handling—where high channel density, rapid update rates, and reliable diagnostics are critical. Its combination of compact form factor, professional-grade protections, and high-speed data exchange make it an ideal choice for modern control system designs.
