Product Description:

The RECO RMA12.2-16-DC024-200 is a digital output module built by Bosch Rexroth Indramat for the RECO Drive Modules series. Mounted within a modular rack, the unit converts control data from the drive system into discrete switching signals for connected field devices. These signals can operate solenoids, contactors, or indicator lamps used in automated equipment. By providing electrically isolated electronic switches, it allows field devices to run from a common 24 V supply while remaining logically coordinated through the system bus.

Bus communication is handled through the INTERBUS interface, so cyclic process data and diagnostic words are exchanged with the controller without additional wiring. The module transmits and receives a parallel data word that is 16-bit wide, matching the physical arrangement of its 16 output channels. Each channel uses a FET output switch rated for 2 A continuous load current, which is suitable for typical pneumatic valve coils, pilot relays, and similar loads. Outputs are arranged in two galvanically separated groups of eight, which helps reduce ground loops and supports separate field power sections when needed. The overall depth of the housing is 81 mm, allowing dense stacking in shallow cabinets.

Internal protective features support stable operation during normal switching duty. Current limitation is handled inside the circuitry, and internal voltage monitoring disconnects the stage if the supply strays from the nominal 24 VDC level. The design is short-circuit proof, so a downstream fault will not damage the switching transistors under typical fault conditions. Physically, the unit occupies 41.3 mm of rack width and stands 192 mm high, which helps it fit compact control cabinets. The module uses 2 isolated groups with eight outputs per group, allowing separate distribution paths for connected loads.
