Application
PR electronics 3118 Bipolar isolated converter splitter
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).
Technical characteristics
PR electronics 3118 Bipolar isolated converter splitter
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.
All terminals are protected against overvoltage and polarity error.
Meeting the NAMUR NE21 recommendations, the 3118 ensures top measurement performance in harsh EMC environments.
High galvanic isolation of 2.5 kVAC.
Fast input to output response time < 7 ms / > 100 Hz – 10 Hz bandwidth damping possible via DIP-switch.
Excellent signalT67M.gif)
ise ratio > 60 dB.
