1 CH, LOAD CELL / STRAIN GAUGE BRIDGE ISOLATING CONVERTER, SIL 2 DESCRIPTION The single channel DIN Rail Load Cell/Strain Gauge Bridge Isolating Converter D1064S acts as a galvanically isolated interface installed between a PLC/DCS in Safe Area and a load cell (or group of load cells) in Hazardous Area. Up to four 350 Ω load cells, or five 450 Ω load cells, or ten 1000 Ω load cells can be connected in parallel. It provides a fully floating power supply voltage with remote sensing capabilities to load cells located in Hazardous Area and converts the mV signal from the load cell into a 0/4-20 mA or 0/1-5 V or 0/2-10 V signal according to user desired range. Output circuit provides both current source and sink capabilities. Modbus output is also provided to interface PLC/DCS using digital communication.
