Product Description:

The R-IB IL 24 PWR IN is a power-feed interface module manufactured by Bosch Rexroth Indramat for the R-IB Interface Modules series. Installed on an Interbus segment, the unit introduces a 24-volt supply rail and common return so that distributed digital or analog terminals can operate from the same source. In compact control cabinets, it functions as the transition point between the system power supply and the field bus, assuring that downstream devices receive regulated energy without additional wiring complexity.

The module is designed for a nominal bus voltage of 24 V DC and can pass up to 8 A to connected inline terminals. A maximum AC component of 5% is tolerated on that supply, helping protect logic electronics from ripple-induced errors. The enclosure is rated IP20, so the device must be mounted inside a closed panel. Functional insulation between the input circuitry and the communication spine is verified at 500 V AC test potential, limiting leakage in the event of wiring faults. With a housing width of only 12.2 mm, multiple power feeders can be placed side by side without consuming excessive DIN rail space.

The plastic case measures 119.8 mm high and 71.5 mm deep while weighing just 59 g, making it suitable for vibration-sensitive installations where low mass is preferred. The product is classified as Class III, relies on an SELV supply, and therefore does not include an internal fuse; overcurrent protection must be provided upstream. Spring-cage terminals allow tool-free insertion of rigid or ferruled conductors, and polarity-reversal protection helps block accidental miswiring. Surge suppression is incorporated across the supply rails, but there is no segment short-circuit detection or integrated Interbus chip, so diagnostic tasks are handled by the higher-level controller.
