ISO-300 I/I – 4-20mA/420mA Signal Isolator

The ISO-300 I/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 with high precision and high linearity throughout the range. It has the special feature that it does not require an auxiliary power supply. The 4-20mA loop at the input takes care of powering the circuit itself, which generates the output current in an active and galvanically isolated manner. Among countless applications, the ISO-300 I/I can be used together with transmitters, frequency inverters, PLCs, process controllers, and others.
