For PLCs that do not have analog outputs, often the pulse rate of a discreet output can be programmed to vary. By connecting the APD 7580 to this output, a proportional analog signal can be generated. A 15 VDC power supply is provided to power the sensor input, if required.Full 3-way isolation (input, output, power) makes this module useful for ground loop elimination, common mode signal rejection or noise pickup reduction.The APD 7580 input and output can be field-configured via external rotary and slide switches. Common ranges are on the module label. Many additional combinations are possible. Consult the factory for assistance with special ranges.Sink/Source Versatility For 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.LoopTracker API 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 from 0 to 100% of output span. The output test button greatly aids in saving time during initial startup and/or troubleshooting.
