The ISO-100 U/I signal isolator is used for electrical isolation of instrumentation loop electronics in order to avoid various problems, especially in systems that can be influenced by noise, such as harmonics and ground loops. It comprises an analog input (0 – 10 Vdc) and an analog output (4 – 20 mA) of high precision and linearity over the entire range. Among countless applications, the ISO-100 U/I can be applied together with transmitters, frequency inverters, PLC’s, process controllers, among others.
