application
1:1 standard current signal isolation, signal range 0(4)... 20 mA.
Standard DIN rail installation.
Both in terms of technology and cost, it is the choice of electrical isolation of current signals.
It can effectively suppress the surge current and protect the control system from the influence of signal noise and transient.
Eliminate the ground loop and measure the floating signal.
Install in safe Zone or Zone 2 and Cl. 1 Div 2.
Technical characteristics
The 3185 is driven only by current input signal without separate power supply.
Low input voltage drop, typical value 1,35 V + Vout.
< very high conversion accuracy, better than 0,1% signal range 0... 20, 5 mA.
Function range is 0... 23 mA, meaning that 3185 meets NAMUR NE43 standard requirements.
Input and output float and electrical are independent of each other.
The maximum output voltage is 17,5 VDC.
High electrical isolation performance 2,5 kVAC.
Fast response time < 5 ms.
Excellent SNR > 60 dB.
