Product Description:

The RMA02.1-16-RE230-200 is an output relay module built by Bosch Rexroth Indramat for the RECO Drive Modules series. It plugs into the series backplane to translate low-level control signals from a drive or PLC into field-rated contact closures. By adding isolated power switching directly inside the drive rack, the board lets automated lines energize solenoids, motor contactors, stack lights, and safety interlocks while keeping higher voltage away from logic circuitry. This arrangement also helps separate control-level electronics from the switched load circuits inside the cabinet.

Every channel uses a relay contact, so an electromechanical armature rather than a semiconductor carries the load current. The contacts are rated for up to 230 Veff, permitting direct connection to plant mains or control transformers. Steady conduction is limited to 2.0 A per channel, which helps protect the contact surfaces during continuous duty. Mixed circuit designs are possible because the relay can switch AC and DC supplies without regard to polarity. Command behavior follows Active 1 logic, meaning the coil energizes when the backplane drives a high-state signal. This makes the module suitable for applications that need simple isolation between control commands and external loads.

The card provides 16 individually addressable outputs arranged into 2 galvanically separated banks, and each bank offers 8 terminals for orderly field wiring and selective fuse protection. All outputs are floating, so neither pole is tied to system ground, which helps reduce unwanted ground-loop paths when actuators use different supply potentials. Despite the high channel density, the board weighs only 440 g, which helps keep installation manageable in compact cabinets. The grouped layout also makes it easier to separate loads by function, such as signaling devices on one bank and contactor or valve circuits on the other. This organization supports machines that need many discrete switched outputs in a limited amount of rack space.
