PR Electronics 3100 Series Isolating Signal Converter Current Input Current Output 0 - 20.5 mA 16.8, 31.2 V dc Supply ATEX 3103

PR Electronics 3103 Isolated Signal Repeater is part of the 3100 Series designed for precise isolation and 1:1 conversion of standard current signals. It excels at providing galvanic isolation of current signals to SCADA systems or PLC equipment, ensuring signal integrity and protection against interference. This device operates with a supply voltage of 16.8 V dc and 31.2 V dc, supporting input and output current ranges of 0 to 20.5 mA.

The 3100 Series devices are compact Signal Conditioners with a slim 6 mm housing, offering exceptional performance and electromagnetic compatibility (EMC) immunity suitable for indoor and outdoor industrial environments. They are designed to withstand wide ambient temperature variations from -25°C to +70°C, making them ideal for locations with fluctuating conditions.

Equipped with advanced microprocessor technology, the PR 3103 ensures high base accuracy of 0.05% throughout available signal ranges. It features a low temperature coefficient of less than 0.01% per °C and long-term accuracy better than 0.1% over three years without requiring recalibration. Installation is straightforward via DIN rail mounting with screw terminals, allowing both vertical and horizontal orientation without air gap separation.

Its galvanic isolation rating of 2.5 kVAC provides robust noise immunity and effectively prevents ground loops, enhancing measurement reliability. The device is protected against over-voltage and incorrect polarity wiring, ensuring safe and error-free installation. A front LED indicator displays device status and alerts to setup or hardware errors.

Programmed using DIP switches, the 3103 model offers pre-calibrated input/output ranges that can be changed by simply toggling switches and power cycling - eliminating the need for manual recalibration. Select versions also enable HART programming for enhanced configurability.
