Description
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.
