The single channel DIN Rail Load Cell/Strain Gauge Bridge Isolating Repeater D1063S acts as a transparent galvanic isolated interface installed between a weighing indicator in Safe Area and a load cell (or group of load cells) in Hazardous Area; it appears at the terminals of the indicator as a single load cell equivalent to the one in the field.
Provides a fully floating power supply voltage with remote sensing capability to load cell located in Hazardous Area and repeats, while isolating, the mV signal output to drive a load in Safe Area depending on the host system reference voltage. Up to four 350 Ω load cells, or six 450 Ω load cells, or twelve 1000 Ω load cells can be connected in parallel. Voltage reference (Safe Area side) is DIP switch configurable to select internal or external (host system) supply. In addition a field wiring fault red LED indicates any wire break in the Hazardous Area side.
