RMG12.2-NNK26/03

The RMG12.2-NNK26/03 belongs to the RECO Drive Modules series produced by Bosch Rexroth Indramat. It is a gateway-level component that links modular drive racks to higher-level control networks within automated machinery. By translating fieldbus signals and monitoring power redundancy, the module helps coordinate multiple drives and keeps communication intact when supply conditions fluctuate.

As a Gateway Module, the unit is intended to pass telegrams between local drive electronics and the plant network without modifying data content. Produced by Bosch Rexroth Indramat, it matches the mechanical outline, connector pitch, and diagnostics scheme defined for the RECO Drive Modules series, simplifying cabinet layout. The device supports the INTERBUS fieldbus standard, so cyclic process data can be exchanged at the remote I/O level using a single twisted-pair backbone. It appears to the bus master as a Remote BUS Slave Device, meaning that address assignment, baud-rate selection, and watchdog timing are controlled centrally while the module only answers to polling requests. These roles allow deterministic communication and predictable scan times inside motion-centric production lines.

Its provision for Interruption-Free Automatic Changeover to Second Power Supply Unit safeguards the drives against voltage dips that could otherwise stop axes mid-cycle. Within the wider RECO architecture, the module constantly compares the health of both incoming supplies and shifts the load in less than one network frame. This built-in Automatic Changeover strategy eliminates the need for external redundancy relays so that a second power supply unit can assume the load without breaking the bus link. By merging bus translation with supply monitoring, the module streamlines panel wiring and minimizes recovery time after a primary supply fault.
