General Description:
The JSD TTC-1001 series of JSD Technology is a thermocouple signal isolation transmitter with one input and one output. This product is an isolation transmitter that uses a thermocouple sensor to measure temperature (the thermocouple sensor needs to be equipped by the user). Mainly used to measure the temperature around -270ºC~+2800ºC. The thermocouple isolation transmitter JSD TTC-1001 is a digital circuit structure with a cold junction compensation function, and adopts advanced technologies such as ambient temperature self-compensation and zero point automatic calibration. It is calibrated according to the thermocouple national standard graduation table before leaving the factory, so it can It is guaranteed that the accuracy is within the specified range for many years, without frequent calibration. The product has functions such as online fault self-diagnosis, and is an intelligent temperature transmitter product.

JSD TTC-1001 series of JSD TTC-1001 are completely isolated (three isolation) between input, output and working power supply. The product adopts SMD and wide creepage design, which can make the product withstand 3000VDC isolation withstand voltage. The equipment adopts DIN35 international standard guide rail installation method, which is small in size, high in accuracy, stable in performance, and cost-effective. It can be widely used in petroleum, chemical, electric power, instrumentation and industrial control industries.
For Single channel input dual-channel output thermocouple signal isolation transmitter Please choose: JSD TTC-1002 series; dual-channel thermocouple signal isolation transmitter Please choose JSD TTC-2002 series.

Output status:
Follow mode: Under the circumstance that the user does not specifically specify, regardless of the fault state of the input signal (except for disconnection, the disconnection output is 0V/mA), the output will follow the input signal change within the full scale range, but the maximum output will not exceed the output 110% of the upper limit of the range (such as 0-20mA output, the minimum output can be 0mA, the maximum does not exceed 22mA).
Indicator light description:
PWR:Power indicator (green). When the meter is energized, it stays on.
ALM: Input signal status indicator, red. The indicator does not light up in normal working state;
The indicator flashes when the input signal fails;
When the input signal exceeds the range, the indicator will stay on.

Note :
When thermocouple is input, the compensation wire should be directly connected to the input terminal, and no wires of other materials should be connected in the middle, otherwise it will cause measurement errors
