PR Electronics 3 Series Signal Conditioner, Current Input/Output, 35 V dc, 6 V dc Supply, IECEx/ATEX 3186B2

PR Electronics 3186B2 Signal Conditioner is a 3 Series model designed for accurate isolation and signal conditioning of current signals in industrial environments. It supports input and output current signals ranging from 3.5 to 23 mA with a supply voltage of 35 V dc and 6 V dc. Certified for hazardous environments under IECEx and ATEX standards, this device ensures secure operation in zone 2 areas.

The isolator features galvanic isolation at 2.5 kVAC, effectively eliminating ground loops and providing enhanced noise immunity. With a high accuracy of 0.05% and a low temperature coefficient better than 0.01% / °C, it maintains precise measurements from -25°C up to 70°C, suited for demanding industrial and automation applications.

It supports rapid transmission of process measurement changes to PLCs or DCS systems, enabling fast and accurate monitoring of critical signals. The unit is loop-powered and designed for DIN rail mounting, allowing flexible vertical or horizontal installation without air gap separation. DIP-switch programming allows easy range adjustments without recalibration, simply requiring a power cycle.

A front panel LED provides device status indication, including error warnings, while the device terminals include protection against over voltage, polarity mistakes, and incorrect wiring. This robust industrial Signal Conditioner is compliant with multiple international standards such as DNV-GL Marine certification, LVD 2014/35/EU, RoHS, EMC directives, UL 61010-1, and EAC TR-CU.

The PR Electronics 3186B2 is widely used in industrial automation, process control, electrical panels, and hazardous area electrical installations for accurate and safe signal isolation and conditioning. This model ensures long-term stability with better than 0.1% accuracy over 3 years without re-calibration.
