Series Current/Voltage Input Distribution Isolators (Loop power supply),
series passive isolator is use to connect to on-site two wire transmitters, provide
power to them, and receive -mA current signals from the two wire equipment output. After
isolation, it outputs a -mA current signal. Adopting a two wire loop power supply method, there
is no need for external power supply.
The THP-I/U series passive isolator receives DC current or DC voltage signals from the site, and
after interference suppression, isolates and outputs a -mA current signal. Adopting a two wire
loop power supply method, there is no need for external power supply.
