Loop Powered Isolator to 3 KV
OTEK releases its model LPI opto-isolated loop powered transmitter that uses no transformers and choppers that reflect noise on the transmitter’s line. The transmitter uses a special technique to convert the incoming 4 mA to 20 mA frequency to drive the opto-isolator. The device comes in a miniature plastic case (metal on request) that can be din-rail mount, Velcro attached or in line with existing wiring. VDC and Hertz I/O options are also available. The LPI is useful in hazardous applications as an isolator or buster where existing lines are overloaded. Nuclear, Mil-Spec and industrial versions are available (intrinsically safe on request).
