- Economical
Description
Description
The DRC-4710 and DRC-4720 DIN rail mount signal conditionersare self-contained DC powered modules designed for bridge input(load cell, strain gage) or voltage input (not connected to a bridge,excitation supply not used). These signal conditioners contain aprecision instrumentation amplifier, filtered output and a built-in 10Vexcitation supply capable of driving a 350 Ω bridge.
The 0 to 30 mV input range makes the DRC-4710 and DRC-4720compatible with most strain gage based load cell or pressuretransducer outputs. Two models are available, one with 0 to 10 Vdcoutput (DRC-4710), and the other with 4 to 20 mA output (DRC-4720).Connections are made via easily accessible screw terminal blocks.Zero and Span adjustment potentiometers are locatedexternally as well for easy access.
