Modbus / KNX interface for RDZ air handling units

DIN-Rail mount modules - DIN-Rail mount modules



The Ekinex® EK-BO1-TP-RMA interface is a modular KNX S-mode device that allows bidirectional communication between the RDZ air handling units, equipped with control board with RS-485 Modbus communication port, and the KNX system (TP). Thanks to the interface, the functions performed by the air handling units can be controlled and monitored by KNX devices. The unit has an integrated KNX bus communication module and is realized for mounting on a 35 mm rail. Power is supplied via the KNX bus.

  • Housing in plastic material
  • Mounting on 35 mm rail (according to EN 60715)
