The DRC-4710 and DRC-4720 DIN rail mount signal
conditioners are 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 a
precision instrumentation amplifier, filtered output and
a built-in 10V excitation supply capable of driving a
350 Ω bridge. The 0 to 30 mV input range makes the
DRC-4710 and DRC-4720 compatible with most strain
gage based load cell or pressure transducer outputs.
Two models are available, one with 0 to 10 Vdc output
(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 located externally as
well for easy access.
