PHG-11TT-*8+
Overview
The PHG-11TT-*8+ thermocouple input temperature converter with surge protection function can transmit the millivolt signal from thermocouple (TC) and output in 1: 1.
This product requires independent power supply, with isolated power supply, input, and output terminals.
"*" represents the input type of the thermocouple, and the specific model is represented by a code (see "Input Signal Type and Range Table" for details).
| 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% |
For example: one input and one output, thermocouple K (-200~1370C) input, one channel 1:1 output, 24V power supply, model: PHG-11TT-18
