RTD input Temperature converter

PHG-12TZ-461  1 input 2 outputs

Input :Two-wire or three-wire RTD Pt100 signal

Output :One channel RTD Pt100 signal, one channel 4~20mA signal


    The thermal resistance input temperature converter can isolate and convert the thermal resistance (RTD) signal to output a 1:1 correspond signal and a 4~20mA signal for driving the load. Intelligent configuration is possible, and the actual range of the thermal resistance can be set through computer software.
    This product requires independent power supply, and the power supply, input and output are isolated.


    Input signal Two wire or three wire Pt100 signal
    Measurement range -200-850
    Output signal RTD Pt100 signal and 4~20mA signal
    load capacity 0~500Ω(can be customized)
    Supply voltage 20-35VDC
    Power consumption <1.9W (when 24VDC power supply, at 20mA output )
    LED indicator Green: Power indicator
    Output accuracy 0.1%F.S
    Temperature drift 0.1%F.S/10℃
    Temperature parameters Working temperature: -20~+60, storage temperature:-40~+80
    Relative humidity 10%~95% RH no condensation
    Dielectric strength ≥2000VAC/min (between input/output/power supply)
    Insulation resistance ≥100MΩ (between input/output/power supply)
    Electromagnetic compatibility According to IEC 61326-1(GB/T 18268), IEC 61326-3-1
    MTBF 100000h
    Wire requirements Horizontal cutting surface ≥ 0.5mm2; Insulation strength ≥ 500V
    Applicable field equipments Two wire or three wire RTD Pt100



     Schematic diagram



    1. 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"

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

    3. When inputting a two-wire RTD, terminals 5 and 6 must be short circuited
