If needed, this supply can be used to power a passive sensor, eliminating the need for an additional external power supply.Common applications include frequency to DC conversions from frequency output type devices such as rotary encoders, magnetic pick-ups, variable speed drives and flow meters.A PLC pulse rate output can be programmed to vary. By connecting the APD 7010 D to this output, a proportional analog signal can be generated.Sink / Source VersatilityFor maximum versatility the output can be selectively wired for sinking (unpowered) or sourcing (powered) milliamp output. The 20 VDC loop excitation supply can be used to power a milliamp current loop if required. The output can also be wired for an externally powered loop.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 the test button to provide a fixed output (independent of the input) when held depressed. The test output level is potentiometer adjustable 100% of the output span. The output test button greatly aids in saving time during initial startup and/or troubleshooting.
