SFI762 - Special Function Isolator

Product Diagram

The SFI762 combines two fully independent and isolated input channels and one output for the following process control signal conditioning applications:

  • Addition (Output = Input 1 + Input 2).
  • Subtraction (Output = Input 1 - Input 2).
  • Minimum Selection (Output follows the lower of the two inputs).
  • Maximum Selection (Output follows the higher of the two inputs).

The special function is factory configured however both the inputs and the output can be coding plug configurable for common process signals (Factory default is 4-20mA in and out).

Final calibration can be trimmed by using the front accessible SPAN (S) and ZERO (Z) potentiometers. Isolation is 2kVrms between inputs output and supply eliminating traditional problems with special function transmitters. The two inputs can be set to dissimilar input types and optional card input is available for both inputs. The wide swing DC/DC converter allows for two power supply ranges: 10-60Vdc (16-42Vac), 80-280Vac (80-300Vdc).
