Ürün Açıklaması
  • 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

Application

  • 1:1 input loop powered isolator of current signals in the range 0(4)...20 mA.
  • 3185 is an easy mounting DIN rail unit.
  • A very competitive choice in terms of both price and technology for galvanic isolation of current signals.
  • Provides surge suppression and protects control systems from transients and noise.
  • 3185 eliminates ground loops and can be used for measuring floating signals.
  • The device can be mounted in Safe area or in Zone 2 and Cl. 1 Div 2. area.


Technical characteristics

  • 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.


Mounting / installation / programming

  • DIN rail mounting with up to 330 channels per meter.
  • Temperature operation range is from -25...+70°C.
