PR Electronics 3100 Series Bipolar Isolated Converter Current/Voltage Input Output 16.8V 31.2V DC 3118

PR Electronics 3118 Bipolar Isolated Converter is a high-performance signal conditioner designed for industrial automation and electrical signal conditioning applications. It accepts current and voltage inputs and provides corresponding isolated output signals, supporting both uni- and bipolar configurations. With a supply voltage of 16.8 to 31.2 V DC, this device ensures secure galvanic isolation at 2.5 kVAC, thereby minimizing noise and protecting control systems from transient disturbances.

Engineered for harsh industrial environments, the converter operates efficiently within an ambient temperature range of -25°C to 70°C and features an IP20 rating, making it suitable for indoor installations on DIN rails. Its compact 6 mm width allows space-saving integration in control cabinets.

The 3118 model achieves outstanding accuracy of 0.05% and low temperature coefficients (better than 0.01% per °C), maintaining stable measurements over time and temperature variations. It implements advanced microprocessor technology offering surge suppression and is compliant with international standards such as 2014/30/EU, IEC 60068-2-6, ATEX zone 2 certification, NAMUR NE21, and UL 61010-1, suitable for demanding industrial and marine settings.

Installation is user-friendly with the capability to mount vertically or horizontally without an air gap. DIP-switches enable quick setting changes without the need for recalibration, and LED indicators provide real-time device status monitoring for fault diagnosis.

This bipolar isolated converter is ideal for applications in industrial process control, automation systems, signal conditioning in electrical panels, and monitoring environments where reliable isolation and signal integrity are critical. Package includes the converter and detailed documentation for configuration and compliance.
