DESCRIPTION

ST1100L series, a standard analog amplifier, with 4~20mA current signal input and 4~20mA current signal output, is a passive signal isolation module. 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 and linearity. Besides, the modules 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.

FEATURES

  • Two-port isolation (Between input and output)

  • High linearity (0.1% F.S.)

  • High accuracy (0.1% F.S.)

  • Isolation voltage (3KVDC/ 60s)

  • Low voltage-drop (3V typ: @ input=20mA)

  • Extremely low temperature drift (35PPM/)

  • Industry standard (Operating Temperature Range: -25

    ~ 71
    )

  • High reliability (MTBF) 500000 hours)
