PR Electronics 3100 Series Current Isolator, Current Input, Current Output, 35V dc, 6 V dc Supply, ATEX 3186A1

PR Electronics 3186A1 Current Isolator is a high-precision signal conditioning device designed for current input and output isolation, running on 35V dc and 6 V dc supply. It is engineered to eliminate ground loops and provide galvanic separation to ensure accurate process measurement transmission to PLC or DCS systems. Its compact DIN rail mounting and screw terminal design allow easy installation in industrial electrical panels.

Built to operate reliably in hazardous environments, this isolator is certified for use in ATEX Ex Zone 2 areas and meets important international safety standards such as IECEx, FM, UL 61010 / 508, and others. Its wide operating temperature range from -25°C up to 70°C ensures stable performance in diverse industrial settings.

The device supports input signal currents from 3.5 to 23 mA and outputs a current of 50 mA with a high basic accuracy of 0.05%. DIP-switch programming allows users to change the input/output ranges without the need for recalibration, simply by cycling the power post setting change. This feature combined with low temperature coefficient minimizes drift and offers long-term stability with no requirement for recalibration for up to three years.

High accuracy current isolation with 0.05% basic accuracy. 2.5 kVAC galvanic isolation for excellent noise immunity and ground loop elimination. DIP-switch configurable input and output ranges without recalibration. Robust DIN rail mount design suitable for compact control panels.

Certified for hazardous area installations including ATEX and IECEx Zone 2. Wide temperature range for reliable industrial use. Over-voltage and wrong polarity protection ensures safe wiring. LED indicator provides clear device health and status notifications.

This isolator is suitable for applications in industrial automation, electrical control systems, signal conditioning for monitoring critical process signals, and hazardous location instrumentation. It is widely used in industries such as manufacturing, process control, chemical plants, oil and gas, and power generation sectors.
