Siemens 3RS1721-1ET00 Loop Power Isolator

The Siemens 3RS1721-1ET00 is a 1-channel interface converter, functioning as a loop power isolator. It accepts a standard 0-20 mA or 4-20 mA input signal and provides an isolated 0-20 mA or 4-20 mA output signal, ensuring signal integrity and protection against ground loops. The module features screw terminals for easy and secure connections.

This signal isolator is commonly used in process control and automation systems to protect sensitive instrumentation and control devices from electrical noise and voltage differences. It's essential for maintaining accurate measurements and reliable operation in environments with multiple grounding points or potential interference.
