The SDAFE™ Analog Modules are pluggable and interchangeable as shown (Channel 1 removed) :

 

Each SDAFE™ Analog Module can be programmed thru the application software to be mA or VDC input. All modules are factory calibrated with 6 break point calibration per input type.

The SDAFE-X55 is an isolated analog signal conditioner. Inputs can be software selected to be either mA or VDC in various ranges and unit types. Signal and power isolation based on the Analog Devices, Inc., iCoupler® technology,

The Isolator Integrated Circuit carries the following Safety and Regulatory Approvals:

  • UL recognition
  • 2500 V rms for 1 minute per UL 1577
  • CSA Component Acceptance Notice #5A
  • VDE certificate of conformity (pending)
  • IEC 60747-5-2 (VDE 0884, Part 2)
  • VIORM= 560 V peak

The SDAFE™ communicates via SPI, and is powered from a single +3.3VDC or +5VDC source. The A/D converter is a 15 bit A/D.

Standard Ranges:

  • 0 - 20 mA
  • 0 - 5 VDC
  • 0 - 10 VDC
