I. Overview
The SFG series intelligent isolation converter adopts multiple advanced isolation methods to achieve three terminal isolation of power supply, input terminal, and output terminal, as well as signal transmission and conversion. The product adopts high-quality semiconductor devices and SMT surface mount technology, and is widely used in systems such as petroleum, metallurgy, and power. This isolator has strong anti-interference ability and is suitable for use in situations with large power fluctuations. The power supply range is 100-260VAC/DC or 24VDC.

Main Features
The intelligent signal isolator is easy to operate, has strong universality, and can be used for multiple purposes with one meter. Users can input/isolate multiple signal types through keyboard settings.
Software zero and full adjustment, eliminating measurement errors caused by temperature drift, with an accuracy better than 0.1% Fs.
High isolation performance, strong anti-interference ability, high conversion accuracy, and stable performance.
The standard DIN (35mm) guide wheel installation method and the design of pluggable terminals greatly facilitate user use.
