Other characteristics


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) Protection degree IP20 (installed device) Safety class II Weight 70 g 2 modular units (1 unit = 18 mm) Dimensions 36 x 94 x 71 mm (WxHxD) Power supply 30 Vdc from KNX bus line Current consumption (from main bus line) < 13 mA The interface represents a node on the KNX network and performs the Master function on the Modbus network to which the control board of the air handling unit is connected as the only Slave. The interface manages a bidirectional data flow between Modbus RTU (Remote Terminal Unit) and KNX. The Modbus registers are read cyclically and their value can be sent as a communication object on the KNX bus. The data update on the KNX network can take place cyclically and/or on variation event of the data acquired by the Modbus network. The interface acquires the value of KNX communication objects during the exchange of telegrams on the bus. The acquired value is converted and written on the appropriate Modbus register. The configuration is carried out by ETS by means of the corresponding application program. • 30 Vdc from KNX bus line • Current consumption (from main bus line) < 13 mA
