Product Description:

The R-IB IL 24 DI 32/HD is a digital input interface module manufactured by Bosch Rexroth Indramat and supplied within the R-IB Interface Modules series. It is intended for mounting on inline I/O stations where discrete field signals must be gathered close to machinery and forwarded to the controller over the station backplane. By translating switch, sensor, or relay states into a compact data word, the module supports modular machine design, reduces panel wiring, and targets standard 24 V logic environments found in assembly lines and packaging cells.

Every channel is referenced to a common 0 V line and accepts a nominal level of 24 V DC; the internal input circuit draws only 2.8 mA, minimizing sensor load. A total of 32 inputs are arranged in four logical bytes that are transferred to the controller as 32-bit process data. Field conductors are terminated through 1-conductor spring contacts, so each signal needs just one wire plus the shared reference. The housing carries an IP20 protection rating, matching installation inside a closed control cabinet. Despite the channel count, the body remains compact with a width of 48.8 mm and a depth of 71.5 mm, allowing dense stacking on a DIN rail. The data format aligns each hardware input with a single bit, simplifying addressing in the PLC program.

Change detection is fast: the hardware requires only 2 ms from a rising edge to report an active state and maintains the status for an additional 4 ms after the signal disappears to filter noise and debounce mechanical contacts. Electrical thresholds are clearly defined; a logical zero is guaranteed when the terminal sees less than 5 V DC, while a logical one is assured once the level exceeds 15 V DC. These timing constants and switching points ensure deterministic scan cycles and reliable distinction between true events and transient disturbances on high-density input banks.
