Surge Protection Type RTD input temperature converter

PHG-11TZ+  1 input 1 output
PHG-12TZ+  1 input 2 outputs

Input :Two-wire or three-wire RTD signal

Output :DC signal (current/voltage)


    The RTD input temperature converter with surge protection function can convert the two wire or three wire thermistor (RTD) signals into DC current signals. It can be intelligently configured, and the actual range of the thermal resistance can be set through computer software. It has the functions of wire breakage alarm and out of range alarm.

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


    Technical Data

    Input signal Two wire or three wire thermistor signals (see "Input Signal Type and Range Table" for details)
    Input disconnection The default "low alarm" can be modified to "high alarm" through configuration software
    Signal range Corresponding measurement range of thermal resistance
    Measurement range Users make their own configuration when ordering, and indicate it at the tail number or otherwise.
    Excitation current 800μΑ
    Output signal DC signal (current/voltage)
    Output load capacity
    Surge protection features:
    Nominal discharge current ln(8/20μs) 5kA

    Schematic diagram



    1. PHG-11TZ+ does not include output part 2

    2. The power rail function is an optional function, and users need to specify the power supply method when placing an order

    The selection of power rail connectors can refer to page 89 of the "Annex"

    3. When inputting a three wire RTD, it is necessary to ensure that the three wires are of equal length as much as possible

    4. When inputting a two-wire RTD, safety barrier terminals 4 and 2 must be short circuited
