Gateway interface module EK-BH1-TP-485

DIN railKNXRS485

Device working as a gateway (protocol conversion) between a RS485 serial network with Modbus RTU protocol and a KNX (TP) network. Master function on the Modbus RTU network. Mounting in distribution board on EN 60715 rail (4 modular units, each 18 mm). To be used in KNX installations for home and building automation. Electrically insulated RS485 serial communication port, 1-way DIP switch to activate the line terminator (120 Ohm) Modbus master RTU (Remote Terminal Unit) communication Communication speed from 1200 to 115200 baud Device addressing from 0 to 250 Register exchange of Coil, Input, and Input Register Holding Register type Reading and writing of single and multiple registers Volatile support memory with �Modbus image� buffer of 1440 bytes KNX TP (twisted pair) 9600 baud communication port, electrically insulated from power supply Volatile support memory with �image KNX� buffer of 1440 bytes KNX device with gateway function (protocol conversion) between a serial RS485 Modbus RTU network (Master function) and a KNX TP network over a twisted pair communicaton cable. Ideal application in integration of Modbus devices over a RS485 serial network in a KNXbased automation system for homes and buildings. The Modbus master RTU RS485 ekinex® EK-BH1-TP485 gateway is a KNX modular unit for panel mounting. It allows you to exchange informations with one or more slave devices over a RS485 differential serial network through Modbus RTU (Remote Terminal Unit) protocol. The ekinex gateway acts as Modbus Master. The informations exchanged over the Modbus network are updated over the KNX network by means of a twisted pair (TP) communication cable.
