Brand: PR Electronics
Request a Quote
  • 1 or 2 channel input loop powered isolator
  • Signal 1:1 functional range 0...23 mA
  • Low input voltage drop and fast response time
  • Excellent accuracy and high load stability
  • Slimline 6 mm housing
Features
  • 3185 is powered by the analog input current signal loop.
  • Low input voltage drop, typ 1.35 V + Vout.
  • Excellent conversion accuracy, better than 0.1% in the range 0…20.5 mA.
  • Functional range is 0...23 mA which means that 3185 is NAMUR NE43 compliant.
  • Inputs and outputs are floating and galvanically separated.
  • The output is voltage limited to 17.5 VDC.
  • High galvanic isolation of 2.5 kVAC.
  • Fast response time < 5 ms.
  • Excellent signal/noise ratio > 60 dB.
