Description
The PR 3108 Isolated Repeater / Splitter from PR Electronics (Denmark) is a compact industrial signal conditioning module designed to isolate, duplicate, and transmit analog current signals in automation systems. The PR 3108 Isolated Repeater / Splitter converts a single input signal into two isolated outputs, ensuring reliable signal distribution to PLC, SCADA, and control systems. The PR 3108 Isolated Repeater / Splitter provides galvanic isolation that eliminates ground loops and protects sensitive instrumentation from electrical interference. Its slim 6.1 mm DIN-rail housing allows high-density installation in industrial control panels. Industrial buyers looking to buy PR 3108 Isolated Repeater / Splitter, find a PR Electronics distributor, or source a signal isolator replacement module benefit from its robust construction, high accuracy, and simple plug-and-play operation.
