R-SG3 is a compact converter for strain gauge load cells. Measurement, made using a 4- or 6-wire technique, is available via ModBUS RTU or ModBUS TCP-IP protocols. Load cell sensitivity ranges from 1 to 64 mV/V. The module is a web server configurable. Powered by a 24-bit ADC, the R-SG3 is distinguished by advanced features (piece counter, automatic tare reset, threshold alarm, automatically upgradable firmware) and flexible measurement management (measurements available in both integer and floating point, measurement can be stabilized by noise filter, configurable resolution). The module also supports Peer-To-Peer and ModBUS pass-through functions.
