Digital weight transmitter for load cells with RS232/RS485/USB interface fully configurable (protocol, continuous transmission/master-slave, Modbus RTU, serial parameters).
Optional interfaces: Ethernet and Profibus DP by connection with external converters. Calibration procedure with sample weights or automatic theoretical. Possibility to select normal or fast weight acquisition. 3 Diagnostic status and communication lines LED lights. STAND ALONE configuration of the main parameters via DIP-SWITCH for fast setup and independently from PC. Configuration via PC application for calibration and detailed configuration of parameters.
