Intelligent Thermocouple RTD Temperature Transmitter 4-20mA Output

Model: BRT TCH1

BRT TCH1 Programmable intelligent temperature transmitter is an isolated precision universal RTD TC temperature signal input,  2-wire 4-20mA output signal converter module.

Main Features
● High precision, accuracy grade:≤0.2%.
● Universal TC RTD temperature signal input.
● Reliable 2-wire 4-20mA output.
● 12-40VDC wide range power supply.
● Programmable parameters via software.
●EMC compatible with GB/T18268, IEC6326-1.

BRT TCH1 Intelligent head-mounted temperature transmitter accepts all the types of RTD, TC signal inputs and outputs 2-wire 4-20mA signal. Its input to output is isolated, isolation voltage is 1000VDC, and input temperature signal is in high linear conversion to output. Its operating power supply is 12-40VC. It is widely used with temperature sensors, temperature measuring instruments, display meter, etc.
