The APD 2208 features 2 input channels and 2 output channels in a compact housing. Each input channel is switch selectable for either a DC input or a potentiometer input.

Each DC input is factory ranged to your specifications. mA inputs are sinking. When a potentiometer input is selected almost any full-range potentiometer with a value of 0-100 Ω through 0-1 MΩ can be used without recalibration and without affecting accuracy. Consult factory for offsets or input ranges other than 0 to 100% of the potentiometer range.

The APD 2208 can also be configured as a DC signal splitter or a potentiometer signal splitter. For this application each DC input should be ordered with the same range.

Each output channel is factory ranged to your specifications and provides an optically isolated DC voltage or current output that is linearly related to the input. Sourcing mA outputs are standard. Sinking milliamp or high voltage outputs are optional. Isolation The full 3-way (input, output, power) isolation makes this module useful for ground loop elimination, common mode signal rejection or noise pickup reduction. LoopTracker API exclusive features include two LoopTracker LEDs (one for each output channel) that vary in intensity with changes in the process 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.
