Siemens 3RS1721-1ET00


The Siemens 3RS1721-1ET00 is an interface converter designed for signal isolation and loop powering in industrial automation systems. This device handles a single input channel with a 0/4-20mA signal and provides an isolated output in the same current range. It features screw terminals for secure wiring connections, making installation straightforward. Distributed by BSP Automation, this loop-powered isolator is well-suited for applications requiring reliable signal transmission with electrical isolation. It has since been succeeded by the model 3RS7020-1ET00.
