PR Electronics 3100 Series Loop Powered Isolator Current Input Current Output ATEX 3185A2

PR Electronics 3185A2 Loop Powered Isolator from the 3100 Series is designed for industrial signal conditioning with current input and current output signals. This device is certified for use in hazardous areas with ATEX Zone 2, IECEx Zone 2, and FM division 2 approvals, making it suitable for demanding environments requiring safety and reliability.

The loop powered isolator features galvanic isolation of 2.5 kVAC, eliminating ground loops and ensuring accurate signal transmission to PLC or DCS systems. It has a high basic accuracy of 0.05% across all available signal ranges, with a low temperature coefficient of better than 0.01% per degree Celsius from -25°C to +70°C, ensuring precise and stable measurements under varying temperature conditions.

Mounting is simplified with DIN rail compatibility and screw terminals, enabling easy installation and maintenance. The unit includes surge suppression and polarity protection, safeguarding control systems from electrical noise and incorrect wiring. DIP-switch programming allows users to set input and output ranges quickly without re-calibration; power cycling the unit activates the new pre-calibrated settings.

The isolator complies with various international standards and approvals, such as DNV-GL, EU-RO marine, NE 43, NE 21, EAC, IECEX, FM, UL 61010 / 508, and others, supporting applications in marine, industrial automation, and process control. The device status is visually indicated by a front LED, enabling quick fault detection for effective maintenance.

Typical use cases include industrial automation, process control systems, hazardous area installations, and marine applications where accurate and safe signal conditioning is critical. This robust and reliable isolator facilitates signal integrity and system protection in complex control environments.
