IO04F01KNX is an Eelectron product code supplied for inclusion in the KNXHub product database. The model code has been retained exactly as provided, with the EEL- prefix removed where it was only an alternate spelling of the same model. A reliable model-specific description and technical datasheet have not yet been matched to this exact code. To avoid introducing inaccurate product information, electrical ratings, dimensions, mounting details, protocol capabilities and application functions are intentionally left blank until confirmed from Eelectron documentation. Treat this entry as an indexed catalogue record rather than a completed engineering specification. The record can be enriched when the exact manufacturer product page, datasheet and ETS application are identified.
