• Field-Configurable by U

The API 7580 G accepts a frequency Input and provides an optically isolated DC voltage or current analog output that is linearly proportional to the input.

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. For PLCs that do not have analog outputs, often the pulse rate of a discreet output can be programmed to vary. By connecting the API 7580 G to this output, a proportional analog signal can be generated. 

The full 3-way (input, output, power) isolation makes this module useful for ground loop elimination, common mode signal rejection or noise pickup reduction.

The API 7580 G input and output can be field-configured via external rotary and slide switches. The more common ranges (30 input & 16 output) can be selected from the table on the module. Many additional combinations are possible. Consult the factory for assistance with special ranges.

API exclusive features include two LoopTracker LEDs and a Functional Test Pushbutton. The LoopTracker LEDs (Green for input, Red for output) vary in intensity with changes in the process input and output signals. Monitoring the state of these LEDs can provide a quick visual picture of your process loop at all times. The functional test pushbutton provides a fixed output (independent of the input) when held depressed. The test output level can be field-adjusted via a multiturn potentiometer.

Both the LoopTracker LEDs and functional test pushbutton greatly aid in saving time during initial startup and/or troubleshooting. The built-in 18 VDC unregulated loop excitation power supply can be used to power passive input devices.
