ELX3351-0090
ELX3351-0090 | 1-channel analog input terminal strain gauge, 16 bit, Ex i, TwinSAFE SC
The analog ELX3351-0090 input terminal enables direct connection of a resistor bridge or load cell from hazardous areas, Zone 0/20 and 1/21. The terminal can be connected in 4- or 6-wire technology. The ratio between the bridge voltage U. D, and the supply voltage U. R, is determined in 16-bit resolution, and the load value is calculated as a process value. Apart from automatic self-calibration (can be deactivated), additional functions such as Tara and Freeze as well as dynamic filters are integrated.
