Product Description

XWT Intelligent Digital Temperature Regulating Instrument

1.Introduction:

XWT - 222C (122C)intelligent digital temperature regulating instrument which is produced by our factory particularly serves the special needs of hydroelectric power stations and steam power plants. Our instrument bases on microcomputer technology and owns various diagnostic functions. Interference defense function has many high-techs such as resistance filtering network, active filter and filtering software, which will help the instrument work stably and reliably under electromagnetic interference circumstances.
Due to the advantages above, our instrument can not only be used for power stations, but also in the situation of fierce interference and vibration which will cause the sensor to be damaged easily.

2.main character:

2.1.The relay will not have false alarm during the instantaneous Moment of power in and off.

2.2.  The relay will not have false alarm when thermal resistance breaks down (short-circuit and open circuit).

2.3. The relay will not have false alarm when the lead wire seems to break.
2.4. The relay will not have false alarm when the screw of wire holder does not tightened which will cause vibration.
2.5. The wiring of thermal resistance can be exchanged between two-wire system and three-wire system.
2.6.The input signal can be set;
2.7. Additional DC signal can be output and the range can be set;
2.8. Serial output can be attached to computer communication and RS-485 communication interface;
2.9. E²PROM protect the data when power off and initial set up and working conditions of all parameters can be permanent preservation
2.10. There's backup of verify parameters and can be called directly if necessary.

Explanation of the panel:

:Parameter settings selection key. The set model is transformed accordingly.
: When Parameter changes, the numerical increase in a compression constantly, it will automatically add "1"

: When Parameter changes, the numerical reduction in a compression constantly, it will automatically reduce "1"
: Reset button. Press the button to make the process start from the beginning.
