Load cell transmitter D5263S

The Load Cell/Strain Gauge Bridge Repeater D5263 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 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. It 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 five 450 Ω load cells, or ten 1000 Ω load cells can be connected in parallel. The Voltage reference (Safe Area side) is set as an external supply.SIL 2 / SC 3Input from Zone 0Installation in Zone 2Strain Gauge Bridge Transparent RepeaterUp to four 350 Ω load cells in parallelHigh AccuracyThree port isolation, Input/Output/SupplyTechnical DataSupplyType24 Vdc nom (18 to 30 Vdc), reverse polarity protected.Current Consumption75 mA @ 24 Vdc with four 350 Ω load cells connected, typical.Power Dissipation1.8 W @ 24 Vdc with four 350 Ω load cells connected, typical.InputTypeUp to four 350 Ω load cells in parallel or up to five 450 Ω load cells in parallel or up to ten 1000 Ω load cells in parallel.Integration time12.5 ms.Bridge supply voltage4.0 Vdc nominal.Bridge output signal1 to 4 mV/V.OutputTypeSame as the input signal.Output impedance500 Ω, typical.Excitation voltageexternally applied between 4 V and 15 V.Transfer characteristiclinear.Response time≤ 20 ms (10 to 90 % step change).PerformanceRef.
