product details

Product Advantages

1.Thermocouple signal input: Supports one thermocouple signal input and can process temperature signals from thermocouples.

2.Signal conversion: Convert the thermocouple signal input in the hazardous area into two DC 4-20mA signal outputs, and transmit them to the safety zone.

3.Output intelligent configuration: The output 4-20mA signal can be intelligently configured and set through a computer to meet the range requirements of practical applications.

4.Power supply: An external 20-35VDC power supply is required to provide sufficient power support.

parameter

Input signal types and measurement range
Code	TC model	Measurement range	Minimum range	Conversion accuracy
1	K	-200~1370℃	50℃	0.5℃/0.1%
2	S	-50~1760℃	500℃	1.5℃/0.1%
3	E	-140~1000℃	50℃	0.5℃/0.1%
4	J	-160~1200℃	50℃	0.5℃/0.1%
5	B	250~1800℃	500℃	1.5℃/0.1%
6	T	-200~400℃	50℃	0.5℃/0.1%
7	R	-50~1760℃	500℃	1.5℃/0.1%
8	N	-200~1300℃	50℃	0.5℃/0.1%

Example: when the input is with K-couple, temperature range is 0~1200℃, 2 outputs are 4~20mA, power supply 20~35VDC, then the model should be PHD-12TT-111 (0~1200℃).

The measuring range can be set to the specified 0 ~ 1200℃ range by computer.

* bus terminal power supply, please see appendix for details.
