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 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 the 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, type 1.35 V + Vout.
  • Excellent conversion accuracy is better than 0.1% in the range of 0…20.5 mA.
  • The functional range is 0…23 mA, meaning 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.
