3118 Bipolar Isolated Converter/Splitter

Brand: PR Electronics
  • 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
Features
  • Flexible 24 VDC (±30%) supply via power rail or connectors.
  • Excellent conversion accuracy, better than 0.05% of selected range.
  • A green front LED indicates operation status for the device.

Applications

  • 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).
