Surge protection type TC input temperature converter 

PHG-11TT-*8+  1 input 1 output

Input :TC signal

Output :1:1 millivolt signal


    The   PHG-11TT-*8+ thermocouple input temperature converter with surge protection function can transmit the millivolt signal from thermocouple (TC) and output in 1: 1.

    This product requires independent power supply, with isolated power supply, input, and output terminals.

    "*" represents the input type of the thermocouple, and the specific model is represented by a code (see "Input Signal Type and Range Table" for details).

    Input signal types and measurement range
    Code TC model Measurement range Minimum range Conversion accuracy
    1 K -200~1370℃ 50℃ 0.5℃/0.1%
    2 S -50~1760℃ 500℃ 1.5℃/0.1%
    3 E -140~1000℃ 50℃ 0.5℃/0.1%
    4 J -160~1200℃ 50℃ 0.5℃/0.1%
    5 B 250~1800℃ 500℃ 1.5℃/0.1%
    6 T -200~400℃ 50℃ 0.5℃/0.1%
    7 R -50~1760℃ 500℃ 1.5℃/0.1%
    8 N -200~1300℃ 50℃ 0.5℃/0.1%
