r-tec 380A Encoder Motor Control Unit

Limit of the model identity

According to the product owner’s model description, r-tec 380A is the larger control board used with electronic encoder motors. I-380 is a separate board used only with motors that have mechanical limit switches. This is an initial selection distinction based on the motor’s position-sensing hardware, not a universal compatibility or wiring instruction.

The related local manual is titled r-tec 380 Control Unit. It neither names 380A nor establishes equivalence with I-380. Its voltage, input, protection and adjustment details are therefore not claimed as verified 380A specifications.

Scope of the linked guide

The guide titled r-tec 380 covers three-phase industrial door motor control, mechanical and encoder-limit inputs, and pneumatic-edge, optical-sensor and photocell connections. Mentioning both limit types in that guide does not make 380A and I-380 the same board. DIP and T1/T2 settings belong to this r-tec 380 guide. If the supplied board is marked 380A, confirm its exact model and revision.

Claims about an open board, DIN-rail mounting, I-380 variant, 13 terminals or a fixed cabinet arrangement are not established by this guide.

Page 2 of the linked r-tec 380 guide describes three-phase motors for sectional and rapid PVC doors with mechanical or encoder-based limits. Alongside open, close, start and stop commands, it explains pneumatic-edge, optical-sensor and safety-photocell inputs. Its account also covers stopping and reopening after detection during closing, the automatic-closing wait and overcurrent protection. These are functions of the 380 document; they must not be presented as proven 380A functions until the model identities are matched.

Verify board identity before installation

Request the exact model and revision marked on the offered board, its terminal diagram and the guide for that revision. Compare motor limit or encoder type, three-phase supply and site safety devices with it. The r-tec 380 guide calls for a 10 A three-phase fuse before the controller, isolation before wiring and separation of power and control cables. Qualified personnel must set current, limits and motor direction using the actual board diagram.

Both linked PDF covers say r-tec 380. Neither proves that its revision matches the photographed board or that 380A and I-380 are equivalent names. Written supplier confirmation that the 380 documentation applies to 380A would allow its figures to be attributed clearly later. Until then, the PDFs remain labelled with their original model and alone cannot justify purchasing or wiring a 380A.
