Product Description:

The RMA12.1-16-DC024-200 is a rack-mount output module manufactured by Bosch Rexroth Indramat and supplied within the RECO Drive Modules series. Designed for industrial automation racks, the unit converts controller commands into switched 24 V DC lines that drive relays, solenoids, or indicator lamps. By housing 16 discrete outputs in a single card, it helps consolidate wiring inside drive cabinets. Hot-swap capability in the powered rack allows the module to be exchanged without shutting down the entire assembly. This arrangement suits machine functions that rely on clear on and off switching for basic signaling and actuator control.

Signal exchange with the higher-level control takes place over the INTERBUS fieldbus, so process data is transported cyclically with deterministic timing. The module is classified as Digital I/O, meaning each channel switches a load on or off without analog scaling. There are 16 output channels, addressed in the PLC memory map from Q*.0.0 to Q*.1.7, which provides byte-aligned access across two consecutive words. Internally, the channels are arranged in 2 x 8 groups, which keeps circuit organization straightforward and supports orderly ribbon-cable routing inside the rack. The addressing structure also helps keep output mapping clear in standard PLC programs.

The field side is connected through terminal block X2, while the power return and supply rails are brought out on the common points 0VL, +UL, so the 24 V source can be looped across adjacent cards. The board is 90 mm tall, 210 mm wide, and 40 mm deep, enabling it to fit within standard RECO carrier frames without protruding into door clearances. The terminal arrangement supports orderly distribution of supply and return wiring between neighboring modules. Its compact shape also helps preserve usable space inside shallow cabinet sections while keeping access to the card edge and field connections straightforward.
