Isolated Transmitter
TxxxxAD Series
Active high precision isolated transmitter
FEATURES
Four-port isolation(Signal input, Signal output,
power supply and Isolation power output)
High accuracy (0.1% F.S.)
High linearity (0.1% F.S.)
Isolation voltage(2.5KVDC/60S)
Extremely low temperature drift (35PPM/
℃
)
Industry standard(Operating Temperature Range:
-25 ~ 71
℃
)
High reliability(MTBF>500,000 hours)
The TxxxAD 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 efficient 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 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).
