Product Description:

The R-IB IL 24 DO 32/HD is a digital output interface module manufactured by Bosch Rexroth Indramat for the R-IB Interface Modules series. It sits on an INTERBUS local bus and translates controller commands into switched output signals for actuators such as lamps, solenoids, and contactors. Integrating thirty-two output channels in one compact housing lets machine builders reduce panel width and streamline field wiring in distributed automation systems. This arrangement supports centralized control while placing the output stage close to field devices.

In operation, the module makes available 32 digital outputs that are each rated for 0.5 A, and all channels together can deliver up to 8 A. This allocation allows simultaneous driving of moderate-current loads without external relays. Every output is referenced to a common supply rail and switching takes place at an output voltage of 24 V DC, a level compatible with most industrial control devices and actuators. The device exchanges process data with the host via the INTERBUS local bus; telegrams are transferred at 500 kBit/s, so cycle times remain short even when several nodes share the segment. A protection category of IP20 indicates that the housing is touch-safe for tools and fingers but must be installed inside a cabinet that shields it from liquids or airborne dust.

The housing is 48.8 mm wide, 71.5 mm deep, and 120 mm high, yet it weighs only 135 g, so DIN rail loading remains minimal. Logic circuitry is powered from a separate rail at 7.5 V; this separation isolates sensitive components from the field voltage and limits local bus power dissipation to 1.05 W while drawing just 140 mA from the backplane. Process data occupy 4 bytes of output address space, allowing the controller to write the state of all thirty-two bits in a single transaction. That compact data image helps keep addressing straightforward in bus-based I/O systems.
