Loop Powered Isolator

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 RMS/1 minute and 250 V AC RMS/continuous. LPI51 can be mounted on 35mm DIN rail in a control panel. It has an LED to indicate it is operating.
