The DM4051 provides an isolated voltage or current output proportional to a strain gauge (bridge) input.

The field rangeable product provides 10V excitation and has gold plated jumpers to select the following ranges and functions:

Input/Output Range
Elevated or Suppressed Offset
Bandwidth Range
Voltage or Current Output
Normal or Reverse Acting Output

Connections are made via two 4-pin plug-in terminal blocks. These terminal blocks allow the product to be removed without unwiring the connections.

TYPICAL APPLICATIONS
Measurement of output from load cells, pressure transmitters, and strain gauge sensors. Eliminates ground loops and common mode signals. Single-unit replacement module provides all normal input and output ranges.
