DC Output 0-10V

The SE3-320 Noise Processor includes DC Voltage Outputs that are proportional to the measured sound level. They are ideal for level recorders and input to data logging systems.

  • Selectable dB measurement range
  • Select Fast/Slow, Max or Leq for output
  • Periodic Leq output option

Two Outputs

There are two DC outputs on the SE3-320, so you can select two different parameters to monitor. Both outputs are set to the same measurement range, but you can select different parameters, as described below.

Output Parameters

Each DC output can be one of the following noise measurement parameters:

  • LAFmax (maximum Fast sound level)
  • LASmax (maximum Slow sound level)
  • LAeq,1s (average sound level every second)
  • LCpeak ('C' weighted Peak)
  • LAeq,15 (average sound level over 15 minutes)
  • LAeq,30 (average sound level over 30 minutes)
  • LAeq,60 (average sound level over 60 minutes)

Measurement Range

The overall measurement range of the SE3-320 is 30dB to 120dB. You can process this whole range over the DC output, or you can select the range of interest.

In the example above, the first output is the average sound level every second (probably the most useful parameter available) while the second output is the average over a 15 minute period. Sound levels of between 50dB and 90dB will be mapped onto the output of 0 to 10V.

Power Requirements

The SE3-320 comes with two powering options: USB (5V) or 24VDC. When using the DC output the unit must be powered by 24VDC, it will not work with the USB option. For convenience, the 24VDC power connections are on the same connector as the DC outputs and ground.

Connecting Up

At the rear of the noise processor there is a connector block - the green part on the image. This connector pulls out of its socket and contains screw terminals to connect the following:

  • 24VDC Supply
  • DC Output 1
  • DC Output 2
  • Output Ground (common to both outputs)
