Multi-range DC signal isolation transformer (isolator) (TW-4M)

This terminal-integrated signal converter (isolator) isolates DC signals from other circuits and outputs signals of an amplified and integrated signal level. Input/output range and response speed can be freely changed with the internal DIP switch.
