3185 - PR electronics

1 Loop powered isolator31851 or 2 channel input loop powered isolator Signal 1:1 functional range mA Low input voltage drop and fast response time Excellent accuracy and high load stability Slimline 6 mm housing ApplicationsApplication1:1 input loop powered isolator of current signals in the range0(4)..20 mA. 3185 is an easy mounting DIN rail unit. A very competitive choice in terms of both price andtechnology for galvanic isolation of current signals. Provides surge suppression and protects control systemsfrom transients and noise. 3185 eliminates ground loops and can be used for measuringfloating signals. The device can be mounted in Safe area or in Zone 2 and Div 2. area. Technical characteristics3185 is powered by the analog input current signal loop. Low input voltage drop, typ V + Vout. Excellent conversion accuracy, better than in the mA. Functional range is mA which means that 3185 isNAMUR NE43 compliant.

2 Inputs and outputs are floating and galvanically separated. The output is voltage limited to VDC. High galvanic isolation of kVAC. Fast response time < 5 ms. Excellent signal/noise ratio > 60 dB. Mounting / installation / programmingDIN rail mounting with up to 330 channels per meter. Temperature operation range is from +70 C.
