Product Description:
The RGM12.2-NN is a communication module produced by Bosch Rexroth Indramat for the RECO Drive Modules series. Installed on a backplane beside power and axis cards, it forms the serial bus link between the drive rack and the central PLC while supervising the rack’s low-voltage logic supply. By concentrating fieldbus wiring and control power on one insertable card, the device simplifies cabinet layouts and reduces wiring points in distributed motion systems.
The module operates on a logic rail of 24 VDC, and two voltage supplies keep the communication electronics separate from power distribution. These supplies are galvanically isolated, which helps prevent ground loops between the rack and external controllers. Data exchange relies on the INTERBUS serial protocol. The card contains two Interbus rings that permit a redundant loop topology for higher availability. The incoming ring is cabled through a 9-pin male D-sub connector, and two Interbus-in ports share that header to accommodate parallel equipment. Downstream traffic exits through a 9-pin female connector that hosts two Interbus-out ports, letting additional drive racks or I/O stations be daisy-chained without external couplers.
Electrical stability is maintained by an allowable ripple of 4.0 Vss, so connected supplies must limit residual switching noise below that threshold to avoid bus errors. Cabinet planning is aided by the card’s compact outline: it occupies only 81 mm of depth and 41.3 mm of width on the rail while rising to 214 mm in height, allowing multiple modules to fit neatly within a 200 mm deep enclosure. The front face is slotted for convection, but the overall assembly carries an IP20 protection rating, indicating finger-safe terminals and no protection against directed water jets. When seated in the RECO backplane, the module is intended for cabinet installation with clearance for airflow and separation from other low-voltage equipment.
