PR Electronics 3100 Series Current Isolator with Current Input, Current Output, 35V DC and 6 V DC Supply 3186A2

PR Electronics 3186A2 Current Isolator from the 3100 Series offers a high-performance solution for isolating current signals with precise electrical separation. This two-wire transmitter isolator accepts a current input range from 3.5 mA to 23 mA and provides a stable current output with a range of 50 mA, powered by dual supply voltages of 35V DC and 6 V DC. It is designed for industrial, automation, and control system environments where signal integrity and noise immunity are critical.

The isolator features galvanic isolation rated at 2.5 kVAC to eliminate ground loops and protect control systems from electrical interference, ensuring accurate process measurements. With a baseline accuracy of 0.05% across all available signal ranges and a low temperature coefficient of less than 0.01% per °C, it provides exceptional precision over a wide ambient temperature range from -25°C to 70°C.

The device is compatible with a broad set of hazardous area certifications such as EAC, FM, EU RO marine, UL, IECEx, ATEX, and DNV GL, and meets SIL 2 standards for safe application in critical industrial operations. Mounting is facilitated through a DIN rail setup with secure screw terminal connections for ease of installation and maintenance. Installation flexibility includes vertical or horizontal mounting with no air gap required.

Operational convenience is enhanced by DIP-switch programming that permits users to change input/output ranges without needing re-calibration - power cycling the device after setting the DIP-switch suffices. Additionally, the isolator supports HART communication protocol for selected devices, enabling remote configuration and diagnostics.

Visual indications on the front panel via LEDs provide real-time device status, including error notifications related to setup or sensor issues, improving maintenance efficiency. Terminals are protected against overvoltage and polarity reversal up to ±31.2 VDC, ensuring robust and error-free installation.

This current isolator is widely applicable across industrial, manufacturing, automation, water treatment, and HVAC sectors, serving as a reliable component for signal conditioning and accurate data transmission to PLCs and DCS systems.
