Product Description:
The R-IB IL 24 DI32/HD-PAC interface module is manufactured by Bosch Rexroth Indramat as part of the R-IB Interface Modules series. The unit serves as a high-density digital input slice that converts field-level 24-volt signals into bus-compatible logic levels, allowing a controller to track sensors, pushbuttons, and limit switches from a compact location on the installation rail. Its role in an automation cell is to present organized, electrically isolated status bits to the local bus so upstream processors can execute safety interlocks and sequence logic without excessive point-to-point wiring.
The module accepts a nominal field voltage of 24 V DC, and each channel draws only 2.8 mA, limiting load on proximity sensors and minimizing heat. Internal electronics are powered separately by a 7.5 V DC logic supply so that bus communication is isolated from field fluctuations. The module provides 32 digital inputs through a single-conductor push-in connection system that saves terminal rows. Even with this channel density, the housing measures just 48.8 × 120 × 71.5 mm, allowing additional slices to fit on the rail. Process data are refreshed over the inline backplane at up to 500 kbps, ensuring that state changes propagate quickly to the PLC cycle.
The enclosure has a protection rating of IP20, so the unit is intended for enclosed cabinets where dust and liquid contact are controlled. Input lines may extend up to 30 m from the sensor to the terminal without exceeding the stated signal integrity limits. Once data arrive, the slice maps them into a 32-bit word on the bus, allowing deterministic access to every channel through a single register. The circuitry registers an active level within a 2 ms turn-on delay and releases it after a 4 ms turn-off delay, which supports fast machine interlocks while filtering electrical chatter.
