Product ID: Open_IO LON_SIF Node

Send Inquiry
The LON_SIF node ( LonWorks to serial interface) converts LonWorks from other nodes employing Echelon's Lontalk network protocol to standard Modbus protocol (RTU mode) for communication with Open_MMI/Open_SCADA computer through RS232/RS422/RS485 serial interface, achieve real time monitoring and control application. It can connect up to 64 Open_IO mode in one LonWorks channel through 78Kbps twisted-pair network bus.
