Product Description:

The R-IB-IL DOR-LV-SET module is an interface element produced by Bosch Rexroth Indramat for the R-IB Interface Modules series. It transfers relay commands from the system bus to field wiring and mounts on a DIN rail inside distributed control cabinets. In industrial automation, the part forms a compact relay-output set that enables a controller to energize or de-energize external loads while keeping bus logic and load circuits electrically isolated. This arrangement is useful when control signals must switch contactors, lamps, or other field devices without connecting those loads directly to the bus electronics. It is intended for distributed I/O layouts where output switching must fit into narrow cabinet spaces.

The module's analog and logic supply is passed through, so no local power conversion is required when it is inserted between adjacent terminals. Safe spacing is maintained by a minimum clearance of ≥ 5.5 mm between conductive parts, reducing the risk of arcing inside crowded cabinets. The relay path has been verified with a dielectric test of 4 kV, 50 Hz for 1 minute, confirming insulation strength across the output circuit. Each output occupies only 12.2 mm of rail width, allowing dense packing of multiple sets on the same rail section. The module has no diagnostic indicators, so any required status monitoring must be handled by the host controller.

When several voltage domains share a panel, the module aids segregation because its other potentials are declared as separated from the internal relay bus. Surface tracking resistance is supported by a creepage distance of ≥ 5.5 mm, helping prevent conductive deposits from bridging outputs in humid environments. This layout supports installation beside other terminal modules where relay channels and control voltages are routed through the same cabinet section. The separation between the relay bus and other potentials is useful in cabinets where control-level signals and switched load circuits run side by side over short distances. It also helps keep neighboring circuits apart when multiple output groups are arranged in close proximity.
