Product Description:

The RECO RMG12.2-NN module is manufactured by Bosch Rexroth Indramat for the RECO Drive Modules series. It functions as a power and communication link that fits into a backplane rack to serve distributed drive systems. By combining an isolated 24-volt feed with INTERBUS data lines, the unit supports remote mounting of servo controllers and sensor islands while preserving deterministic bus timing in industrial automation cells.

Incoming control power is rated at 24 VDC, and the internal design provides a redundant, isolated supply so a second feeder can assume the load without manual intervention. A built-in monitoring circuit triggers a automatic switchover whenever the primary source drops outside tolerance, limiting downtime to a few milliseconds. For fieldbus traffic, the module uses the INTERBUS protocol, and two optical-electrical transceivers create galvanic separation from the rest of the rack. With a protection category of IP20, the housing is suited for installation inside closed electrical enclosures where only finger protection against live parts is required. The power stage tolerates up to 4.0 Vss of ripple on the DC line, ensuring stable electronics even with long cable runs or shared supplies. Two counter-rotating rings inside the board maintain continuous telegram flow to downstream slaves.

The mechanical footprint of 41.3 × 214 × 81 mm allows dense stacking on DIN carrier rails while leaving clearance for air circulation between neighboring drives. On the bus, the module appears as a Remote Bus Slave, so the PLC assigns it a fixed address, but the unit does not forward global control commands. Upstream wiring enters through a 2 × 9-pin male connector pair and exits via a dedicated 2 × 9-pin female set, simplifying ring-topology continuation without external junction blocks. Two physical rings are supported, giving separate channels for process data and diagnostics, and the allowable ripple specification protects sensitive encoder supplies connected downstream.
