Isolation converter Passive isolator, 1-channel Input: 4-20 mA Output: 4-20 mA Width 6.2 mm Spring-loaded connection (push-in) Isolating converter SIRIUS 3RS70 for galvanic isolation and conversion of a standard analog signal between the controller and sensors/actuators. , Due to the galvanic isolation, the isolating converters prevent the analog channels from influencing one another. Thanks to their slim, compact design, they require little space on the top-hat rail, particularly in flat control boxes and control cabinets with small line spacing. The high-quality, modern design in titanium gray contributes to the consistent appearance with all Siemens devices in the control cabinet. The clear range of devices covers all applications and thus simplifies logistics and warehousing. , Active and passive single-range, multi-range and universal converters with different supply voltages and connection types for various standard analog signals and other common sensor signals are available. We also offer variants with manual-automatic switching for specific analog value specification. , A suitable potential separation plate and various connection combs are available for the 3RS70 isolating converters. , The 3RS70 isolating converters replace the proven 3RS17 series. , SIRIUS Relay - a program for all cases.
