Description

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.

Rated 5 out of 5 by John H from Good conditioners - work well We have several instruments that came with Weidmuller conditioners, but they were not stable... drifted up and down over time. I replaced them with these Omega conditioners and we've had no further issues. Rock solid and work well. My only copmplaint would be that the terminal blocks are on the tiny side, and different front to back. I had to dig around to find a screwdriver small enough to fit the block.

Rated 1 out of 5 by Anonymous from Wrong Item - Hard to Return This load cell amplifier was recommended for the 120 Ohm load cells. However, it can only drive 300 Ohm load cells. I'm working on returning it, but Omega is dragging their feet.

Rated 5 out of 5 by gr8bgroach from Simple, easy to use Simple product, straightforward and easy to use. I was able to implement this product very quickly right out of the box. We consistently use them for taking load cell measurements and have never had any problems.
