PR electronics 3185 Loop powered isolator. 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.
