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.
