LOOP POWERED ISOLATOR LPI51
Get Price Quote
LPI51 is 2-wire loop powered isolator which requires no external supply as it is powered by its input signal. It has a low loop-drop of only 3.7 V. Isolators prevent damage to valuable PLCs, DCS, etc. from fluctuations in the input signal from field devices. LPI51 eliminates earth and ground loop problems by electrically isolating the input and output circuits. The signal isolator receives and retransmits a 4-20 mA current analog signal seamlessly with a transfer accuracy of 0.1%. LPI51 provides signal isolation of 1500 V AC RMS1 minute and 250 V AC RMScontinuous. LPI51 can be mounted on 35mm DIN rail in a control panel. It has an LED to indicate it is operating

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.
