Temperature transmitter programmer module
Intelligent temperature transmitter (round card) for thermal resistance (RTD), thermocouple (TC) signal input, two-wire 4 ~ 20mA analog output, installed inside the sensor.
It is used to convert various temperature input signals into 4~20mA output signals.
Input: 2 types of RTDs; 10 types of thermocouples (TC).
Equipped with our V1 or V8 serial programming line, the PC host software is used to configure 12 input types, measuring ranges and other parameters.
High precision and built-in cold junction compensation.
Input and output are not isolated.
