Cecomp Electronics, APD 4058, Non-Isolated DC Amplifier for 1 to 4 Sensor, 85-265 VAC, 60-300 VDC PowerFeatures:Adjustable Excitation Power SupplyOne Minute Setup for Hundreds of I/O RangesRemovable Plugs for Faster InstallationInput and Output LoopTracker® LEDsOutput Test or Calibration Resistor OptionsApplications:Load Cell Weighing Systems and ScalesStrain Gauge Pressure Sensors and TransducersTanks, Scales, Extruder Melt Pressure, Crane LoadsThe APD 4058 accepts an input from a strain gauge, bridge type sensor, load cell, or pressure transducer.It filters, amplifies, and converts the resulting millivolt signal into the selected DC voltage or current output that is linearly related to the input. The output is not electrically isolated.The adjustable excitation power supply generates a stable source of voltage to drive your sensor.Input, output, excitation and zero offset are field configurable, via external rotary and slide switches.Offsets up to ±100% of span can be used to cancel sensor offsets or non-zero deadweights (taring).Sink/Source Versatility For maximum versatility the APD 4058 milliamp output can be selectively wired for sinking or sourcing. This allows connection to any type of mA input receiving device.LoopTrackerAPI exclusive features include two LoopTracker LEDs (green for input, red for output) that vary in intensity with changes in the process input and output signals. These provide a quick visual picture of your process loop at all times and can greatly aid in saving time during initial startup and/or troubleshooting.Output TestAn API exclusive feature includes the test button to provide a fixed output (independent of the input) when held depressed. The output test button greatly aids in saving time during initial startup and/or troubleshooting. The test output level is potentiometer adjustable from 0 to 100% of output span. A calibration resistor switch replaces the test button.
