Loop Powered Isolators, Power : 4-20mA 2

The input 4-20mA Signal from a transmitter is measured and converted into isolated 4-20mA Output signal which is exact replica of the input signal. The Circuit on the input side draws power from the 4-20mA input being measured and the output circuit draws power from the 4-20mA 2-wire Output connection. Thus no separate external power supply is needed for the unit. Optical Isolation is provided internally to isolate the input and output signals.
