The API 7010 G accepts a frequency input and provides an optically isolated DC voltage or current analog output that is linearly proportional to the input.

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

Also standard on the API 7010 G is an 18 VDC input excitation supply. 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. The API 7010 G can also be used to convert a PLC pulse rate output to a proportional analog signal.

Output Loop Power Supply

Standard on the API 7010 G is an 20 VDC loop excitation supply. This supply can be used to power passive input devices, often eliminating the need for an additional external power supply.

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 100% of the output span. The output test button greatly aids in saving time during initial startup and/or troubleshooting.
