The SC420i loop powered isolator is a 0(4)-20mA direct current isolator. The isolator derives its power from the input signal and therefore requires no external power supply. The output of the isolator can be connected to any potential within 1kV of the input negative terminal while transients of 2.5kV can be withstood. The isolator is typically used to enable two control and instrumentation devices, e.g. PLC and local chart recorder, with non-isolated inputs, to monitor the same transmitter output simultaneously. Alternatively the isolator can be used to isolate signals from non-isolated transmitters or as a noise reduction device. The device is housed in an ultra-compact DIN rail mounted enclosure, only 18mm wide.
