The Emphatec SigNext - CLIx/1 4-20mA Loop Isolator - CLIx/1 loop isolator requires just 11.2mm of DIN rail and provides up to 3000V of isolation. It is ideal for preventing ground loops while interfacing 4-20mA transmitters to PLC/ DCS analog inputs.

Transformer coupling means the output is powered from the input - no power supply is required in the output circuit. It provides fast response time and excellent accuracy. Because power is being coupled across the isolator the voltage drop measured across the input terminals varies according to the output loop impedance. For this reason transformer coupled loop isolators do not have an input impedance specified in ohms.
