PR 3117 Bipolar Isolating Converter

The PR 3117 Bipolar Isolating Converter is a high-precision signal conditioning module that's ideal for converting bipolar process voltage and current signals into stable unipolar outputs. The 3117, from PR electronics, is suitable for industrial control and measurement systems. Built with exceptional accuracy, better than 0.05 % of span, and a fast response time of less than 7 ms, this bipolar isolating converter ensures rapid, reliable conversion even in demanding environments.

Featuring robust 3-port galvanic isolation, the PR 3117 protects your control system by suppressing transients, eliminating ground loops, and reducing electrical noise. All terminals are safeguarded against over-voltage, polarity reversal, and short circuits, enhancing system longevity and safety.

• Isolating converter for signal conversion of standard bipolar analog process signals into a unipolar analog signal.
• High 3-port isolation provides surge suppression that protects the control system from transients and noise and eliminates ground loops.
• Offers protection for all terminals against over-voltage, polarity, and short-circuit.
• The device can mount in Safe area or in Zone 2 / Division 2 hazardous areas and features approval for marine applications.

This slimline converter is just 6.1 mm wide. Thus, the 3117 is optimized for high-density DIN-rail installations, allowing up to 163 units per meter without air gaps. It supports flexible 24 V DC power via rail or connector and is suitable for installations in safe areas and hazardous locations (Zone 2/Division 2), including marine applications.

• Flexible 24 VDC (±30%) supply via power rail or connectors.
• Excellent conversion accuracy in all available ranges, better than 0.05% of span.
• Fast response time < 7 ms / > 100 Hz bandwidth — 10 Hz bandwidth damping possible via DIP switch.
• Meeting the NAMUR NE21 recommendations, this device ensures top measurement performance in harsh EMC environments.
• Excellent signal/noise ratio > 60 dB.
• High galvanic isolation of 2.5 kVAC.
• Inputs and outputs are floating and galvanically separated.
• A green front LED indicates normal operation and malfunction.
• Wide ambient temperature range: -13 to 158˚F (-25 to 70˚C).

Easy Mounting, Installation, and Programming

Selectable signal ranges via DIP switches simplify configuration, while a front-panel LED provides clear status indication. Compliance with NAMUR NE21 ensures outstanding performance in challenging EMC environments. With a wide ambient temperature range of -13 to 158˚F (-25 to 70˚C), the PR 3117 Bipolar Isolating Converter delivers reliable, adaptable signal conversion for diverse industrial applications.

• Fast and easy configuration of factory-calibrated measurement ranges via DIP switches.
• The narrow 6.1 mm housing allows up to 163 units per meter.
• Units can mount side by side, horizontally, and vertically, without air gap on a standard DIN rail, even at 158˚F (70˚C) ambient temperature.
• Units can be supplied separately or installed on PR 9400 power rail.
