Product Description:

The RECO RMA02.2-16-RE230-200 is an output relay module produced by Bosch Rexroth Indramat within the RECO Drive Modules series. Mounted on the system backplane, it provides sixteen isolated relay contacts that let a controller drive field devices while keeping control electronics separated from load circuits. By offering potential-free switching, the unit prevents feedback into sensitive drive or PLC hardware and simplifies voltage segregation in automation cells. It occupies a single slot in the RECO rack and links to neighboring modules through the standardized bus connector.

The module’s housing is compact for cabinet layouts: it measures 192 mm in height, 41.3 mm in width, and a depth of 81 mm. These proportions let it share rail space with power amplifiers and feedback cards without obstructing ventilation paths. All sixteen outputs are routed to front screw terminals, and the internal relay matrix is organized as 2 x 8 groups. This physical grouping simplifies field wiring by allowing separate fusing or common potentials per bank. The total channel count of 16 lets a single board energize contactors, indicator lamps, or solenoid valves that require discrete on/off control.

Each relay contact can interrupt or make loads drawing up to 2 A while still responding to very small sensing circuits down to 5 mA. The contacts tolerate both resistive and inductive loads because switching power is limited to 220 W, and the maximum permissible line potential is 230 Veff when controlling either AC or DC sources. The use of potential-free switches eliminates a direct connection between the field voltage and the system bus, improving safety in mixed-voltage panels. The AC/DC rating means the same channel can drive low-voltage logic or mains-level heaters without reconfiguration, and the module’s built-in arc suppression extends relay life during repetitive service.
