Specification
PR electronics 3118 Bipolar isolated converter/splitter
Conversion of voltage and current bipolar process signals to uni-/bipolar signals
Multiple signal ranges are selectable via DIP-switches
Splitter function: 1 signal in and 2 signals out
Excellent accuracy, better than 0.05 % of selected range and high output load stability

Application

PR electronics 3118 Bipolar isolated converter/splitter

The 3118 is an isolating converter and splitter which can be used for signal conversion of standard bipolar analog process signals into two individual unipolar analog signals.
The unit offers 4-port isolation and provides surge suppression and protects control systems from transients and noise.
The 3118 also eliminates ground loops and can be used for measuring floating signals.
Mounting of the 3118 can be in Safe area or in Zone 2 and Cl. 1 Div 2 area and is approved for marine applications.
The analog output can be easily configured and programmed to be bipolar in the ranges ±10 mA and ±20 mA (*special setup).
