420I-AAXX-8

The 420I-AAXX-8 is a loop powered isolator generates a second isolated loop from an existing loop. Power is derived from the input signal. No external power supply is required. Three output options are available, 4 to 20mA, 1 to 5V and the 420V which gives a 0 to 10V output from a 4 to 20mA existing loop input, whilst dropping just 5V from the input loop. 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.
