PHG-11TT+/ PHG-12TT+

Surge protection type TC input temperature converter

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

Input :TC signal

Output :DC signal (current/voltage)


    Thermocouple input temperature converter with surge protection function can isolate and convert thermocouple (TC) DC signals into current signals. This temperature converter has built-in cold end compensation and can be intelligently configured. The actual range of the thermocouple 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.


    Input signal K, S, E, J, B, T, R, N thermocouple 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 The measuring range of the corresponding thermocouple is -10~100mV.
    Measurement range Users make their own configuration when ordering, and indicate it at the tail number or otherwise.
    Built-in cold compensation ±1°C(Compensation range -20°C~ +60°C)
    Output signal DC signal (current/voltage)
    Output load capacity Current load resistance ≤500Ω (can be customized)
    Voltage load resistance <5mA (can be customized)
    Surge protection features:
    Nominal discharge current ln(8/20μs) 5kA
    Voltage protection level Up(8/20μs): 60V(line to line)
    Voltage protection level Up(8/20μs): 600V(line to ground)
    According to standards GB/T18802.21-2016(equivalent to 1EC61643-21:2012)
    Supply voltage 20-35VDC
    Power consumption Current output <0.8W; voltage output <0.6W (PHG-11TT+ series)
