DC to DC Isolated Signal Conditoner

Cecomp Electronics, APD HV-DC D, DC to DC Isolated Signal Conditoner, High Voltage DC Input, 9-30 VDC, 10-32 VAC PowerFeatures:Field Selectable I/O RangesZero and Span Output Calibration PotentiometersFull 1200 V Input/Output/Power IsolationInput and Output LoopTracker® LEDsOutput Test ButtonSelectable Sink/Source for Current OutputApplications:High Voltage Battery SystemsDC Motor and Variable Speed DrivesElectric Railway VoltagesPower Supply and Voltage ConvertersThe APD HV-DC D accepts a DC voltage input and provides an optically isolated DC voltage or current output that is linearly related to the input. This module is unique because it is field rangeable for voltage inputs from 100 VDC to 1200 VDC. Typical applications include signal isolation and signal conversion for a high voltage DC input.IsolationThe optical isolation between input and output makes this module useful for ground loop elimination, common mode signal rejection or noise pickup reduction. The module power supply is isolated, resulting in full 3-way (input, output, power) isolation.Fast Field Setup The APD HV-DC D input and output range settings can be reconfigured in the field via external switches. Range settings are on the module label.Sink/Source Output For maximum versatility the output can be selectively wired for sinking or sourcing. The built-in 20 VDC loop excitation supply may be used to power passive mA devices. This allows the APD HV-DC D to work with powered or unpowered mA devices.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 Test An API exclusive feature includes a test button to provide a fixed output (independent of the input) when held depressed. The test output level is potentiometer adjustable from 0 to 100% of output span. The output test button greatly aids in saving time during initial startup and/or troubleshooting.
