Potentiometer to DC Isolated Signal Conditioner

Cecomp Electronics, APD 4008 D, Potentiometer to DC Isolated Signal Conditioner, 18 Field Configurable Output, 9-30 VDC, 10-32 VAC PowerFeatures:One Minute Setup for Hundreds of I/O RangesExternal Switches & Table for Range SelectionRemovable Plugs for Faster InstallationFull 1200 V Input/Output/Power IsolationInput and Output LoopTracker® LEDsFunctional Output Test ButtonSelectable Sink/Source for Current OutputApplications:Over, Under, Out-of-Range Position MonitoringRemote Control of Positioning DevicesSimplify Control of Potentiometer OutputsThe APD 4008 D accepts a resistance input from potentiometer, slidewire, linear position, displacement, or rotational devices and provides an optically isolated DC voltage or current output that is linearly related to the potentiometer position.The APD 4008 D will accept any potentiometer with a value of 0-100 Ω through 0-1 MΩ without recalibration and without affecting accuracy. The APD 4008 D output can be field-configured via external rotary and slide switches. Offsets and/or input ranges other than 0 to 100% of the potentiometer range can also be selected.The full 3-way (input, output, power) isolation makes this module useful for ground loop elimination, common mode signal rejection or noise pickup reduction.Sink/Source OutputThe APD 4008 has a 20 VDC loop excitation supply for the output. This power supply can be used to power a passive mA device. If not required, the APD 4008 D output can be wired as a passive output. Sinking/sourcing versatility allows the APD 4008 D to produce a powered or unpowered mA output allowing it 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 AnAPI exclusive feature includes the 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.
