DESCRIPTION

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 Range and 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.

MOUNTING

The module mounts on a standard H-35 DIN rail. A spring latch holds it in place. The module is demounted by using a screw driver to release the latch. The latch release is accessible at the bottom of the module.
