T1100L-F Isolation transmitter is a kind of two-wire loop powered isolation
module.A isolation power is transmitted from the 4 ~20mA current loop to
power the former two-wire transmitter and receive the 4~20mA current
signal from the two-wire transmitter.Adopting unique electromagnetism
isolation design and high efficiency loop electric-larceny technology
independent power supply is not required for the module, realizing
4~20mA standard signal isolation with high accuracy it match to kinds of
equipment module input attachment (PLC/DCS act); Overcurrent
Protection is designed to protect the isolation module and the latter circuit;
Besides, the module have extremely low temperature drift(no more than
35PPM/ ℃ under -25 ℃ ~+71 ℃ ).The isolation voltage between the input
and output can be up to 3KVDC.
