Digital load cell transmitter D6263S

The Load Cell/Strain Gauge Bridge Repeater D6263 module is a unit suitable for applications requiring SIL 2 level in safety related systems for high risk industries. The unit acts as a transparent galvanic isolated interface installed between a weighing indicator and a load cell (or group of load cells); it appears at the terminals of the indicator as a single load cell equivalent to the one in the field. It provides a fully floating power supply voltage with remote sensing capability to load cell and repeats, while isolating, the mV signal output to drive a load depending on the host system reference voltage. Up to four 350 Ω load cells, or five 450 Ω load cells, or ten 1000 Ω load cells can be connected in parallel. The Voltage reference is set as an external supply.SIL 2 / SC 3Strain Gauge Bridge Transparent RepeaterUp to four 350 Ω load cells in parallelHigh AccuracyThree port isolation, Input/Output/SupplyTechnical Specifications:Supply: 24 Vdc nom (18 to 30 Vdc), reverse polarity protected.
