Product Description:

The RMA12.2-16-DC024-200 is an output module produced by Bosch Rexroth Indramat within the RECO Drive Modules series. Installed on a back-plane beside motion or logic cards, it switches low-voltage loads such as contactor coils, indicator lamps, or small pneumatic valves in automated equipment. Each channel is driven by a solid-state stage, allowing the controller to issue high-frequency on-off commands without relay wear. This arrangement is well suited to machines that require frequent output updates and dependable switching over long operating periods.

Compact dimensions help the module fit densely packed cabinets: its width is only 41.3 mm, the depth reaches 81 mm, and the height stands at 192 mm. Sixteen discrete outputs are available, stated as 16 outputs, so a single card can service multiple actuators. Every channel can supply up to 2 A per output, enough for most 24 V DC solenoids. The switching element is a FET output circuit, chosen for fast rise times and low power dissipation. These solid-state transistors isolate load transients from PLC electronics, and their low on-resistance minimizes voltage drop under load. The compact layout also supports control cabinets where space must be shared with other I/O, motion, and power modules.

Further protection features round out the design. A 2.0 A peak switching current accommodates inrush surges from inductive devices, while the module turns on only when the supply reaches the specified 24 V DC turn-on voltage, preventing chatter during brownouts. The current ceiling is enforced through an internal current limit; if a channel exceeds that point, it is latched off until the fault clears. Outputs are short-circuit proof, and galvanic isolation is arranged as two blocks with eight channels each, separating field wiring into two independent groups. This 2 x 8 layout simplifies power distribution and confines overload events to one side of the card, preserving the remaining channels and upstream controller hardware. Separating the field side in this way also helps reduce the chance that a fault on one group will disturb unrelated loads on the other group.
