DESCRIPTION
The series is a high integration, high efficiency linear active isolation amplifier module, with current signal input and current signal output. These modules, with a high efficiency isolated micro-power source built-in, can provide energy for inner signal processing circuit and a isolation power out for front-end circuit. In the two-wire, three-wire and four-wire transmitter applications, our products largely predigest customers design and helpfully improve the using room ratio of PCB. Adopting electromagnetism isolation technology, it is available to keep higher accuracy and extremely lower temperature drift more than photocoupler isolation. These modules have four-port isolation (input, output, power supply and Isolation power output) .
