PR Electronics 3100 Series Isolating Signal Converter Current Input Current Output 16.8V dc 31.2V dc Supply ATEX 3108

PR Electronics 3108 is a high-performance isolating signal converter designed for accurate and stable galvanic isolation and conversion of DC current signals. This device supports current input and output signals with a supply voltage range of 16.8 V to 31.2 V DC, making it suitable for various industrial automation and control applications. It is ATEX certified for safe operation in hazardous zones.

The 3100 series products are compact, with a 6 mm width, and built using advanced microprocessor technology to ensure low power consumption, excellent noise immunity, and high base accuracy of 0.05%. Its isolation rating of 2.5 kVAC provides superior protection against ground loops and electromagnetic interference, ensuring signal integrity in demanding environments.

The device operates reliably within a wide temperature range from -25°C to 70°C, allowing deployment in indoor and outdoor settings with significant temperature fluctuations. The signal ranges are DIP-switch programmable, enabling users to select desired input and output ranges quickly without the need for recalibration. Cycling power after setting changes activates the new pre-calibrated settings. Additionally, selected devices support HART programming for advanced configuration.

Mounting is convenient with snap-on DIN rail compatibility and lock mechanisms for secure installation. The front-facing LED offers immediate status and error indication, aiding troubleshooting and maintenance. Screw terminals ensure secure and easy wiring with an IP20 protection rating safeguarding against solid object ingress.

Certified to meet standards including UL 61010-1, IECEx, FM, RoHS, and various European directives, the PR Electronics 3108 is suitable for industrial, laboratory, HVAC, manufacturing, and water treatment applications requiring reliable signal conditioning and isolation for PLC, SCADA, and DCS systems.
