Simplified installation using standard DIN rail and plug-in terminal blocks

The D1063S acts as transparent and very accurate galvanic isolated interface installed between a weighing indicator/system in the Safe Area and a load cell (or group of load cells) in a Hazardous Location. The output to the indicator/system is a transparent reflection of a single load cell equivalent to the one/s in the field. The unit located in Hazardous Location repeats with isolation the mV signal output to drive the load in the Safe Area dependent upon the host system reference voltage. Up to four 350 Ohm load cells, or six 400 Ohm load cells, or twelve 1.000 Ohm load cells can be connected in parallel. In addition a field-wiring fault LED indicates any lead break in the Hazardous Location side. Approved for Div. 2 installation.

Hazardous area:

Up to four 6 wire paralleled load cells 350 Ohm, 5 V, 80 mA total capacity.

Safe area:

mV corresponding to Input Bridge voltage. Accuracy, after system calibration: 0.003 %.

Function:

1 channel I.S. input from strain gauge signals, provides 3 port isolation (input/output/supply) and repeats, as a transparent unit, bridge signal output.
