Overview

The analog ELX3351 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 UD and the supply voltage UREF is determined in 24-bit resolution, and the load value is calculated as a process value. Apart from automatic self-calibration (can be deactivated), additiona...
