Siemens 3RS1722-1ET00 Interface Converter is a two-channel passive separator that functions as an interface converter for analog signals in current-loop systems. Each channel accepts an input of 0/4-20 mA and provides a corresponding 0/4-20 mA output, with galvanic isolation between input and output to protect control equipment. The device uses screw-terminal connections for field wiring and is part of Siemens' 3RS17 family of interface converters.
