Product details


Thank you for the purchase of our XMT*-808 series microcomputer based digital temperature controller. 

This manual contains instructions for the install, operations, parameter setting and abnormal diagnosis when operating the XMT*-808.please read and save this manual carefully before starting operation ,so as to insure the steady .

XMT*808 series intelligence temperature controller uses nowadays the most advanced monolithic microcomputer as mainframe,reduce peripheral assembly,and improve the reliability;It adopts the control method of vague theory combined with traditional PID control, and make the control process with the advantage of rapid response、small overshoot、high steady state precision. It is intelligence temperature controller with the function of high performance、high reliability、complete input,its function is suitable to all the occasion needed temperature measurement and control,also be compatible with other industrial parameter measurement and control.

It adopts modular structure,further improve overall performance;The meter is operated with 4-keys,dual row 4-LED display for displaying the measurement value and set value or measurement value and output value, with manual /automatic switch and setting itself function;with characteristic of small volume、low power consumption、convenient operation、steady and reliable of running;They are now widely used for the automatic control system over the area of machinery, chemical, ceramics, light industry, metallurgy, petrifaction, heat treatment industry.

Ⅱ、Technical standard

2.1、Input and range(one meter can be compatible):

① Thermal couple:K(-50~1300℃)、S(-50~+1700℃)、T(-200~+350℃)、E(0~800℃)、


②Thermal resistance:CU50(-50~150℃)、PT100(-20~600℃);

③Linearity voltage:0~5V、1~5V、0~1V、0~100mV、0~20mV;

④Linearity current(with diffluent resistance):0~10mA、0~20mA、4~20mA

⑤Linearity input: -1999~+9999 (user freely setting)


①  Input by thermal resistance , linearity voltage and linearity current 0.5F·S+1

②  Thermocouple input adopt copper resistance or freezing compensate cold end 0.5 F·S +1;

③  Although the meter can measure B、S、WRE during the temperature 0~600℃,its measurement  could not reach 0.5 class;

④  differentiate rate:1、0.1;

2.3、response time: ≤0.5s (filter parameter sets 0)

2.4、Adjusting mode:

①  ON/OFF control method(Return difference can be adjusted);

②  Common PID control(with the parameter of self-setting function)

③ Intelligence adjustment(including vague PID adjustment and advanced control algorithm with the parameter of self-setting function);

2.5、Output specification:it make out directly output parameter modularity or without modularity:

①The switch of relay contact point output(open+ closed):250VAC/7A or 30VDC/10A;

②SSR voltage:12VDC/30mA(apply for driving SSR relay);

③Contact point output with controllable silicon: can contact 5~500A two directions controllable silicon;2 separate directions controllable silicon opposite direction parallel.  

④Liner electric current output: initial current and terminal current value can be defined when the output is 0~24mA(voltage range 11~23VDC);


Support RS485communication mode,adopt AIBUS communication agreement,and baud rate support the below selection :1200bps、4800bps、7200bps、9600bps


Support two passive contact output,relay contact 250VAC/7A;It has four methods including upper limit, lower limit, positive deviation ,negative deviation .It can output 2 ways at most;

2.8、Tolerance for pressure when it is segregated:Between electric power ,relay’s contact and signal’s end ,do 2000V pressure tolerance test 1s,there is  no abnormal phenomenon; 

2.9、Movement with hand: Automatic /Manual;

2.10、Power supply: 

①  85V-242VAC,50-60HZ;power consumption ≤4W

②  24VDC/AC power consumption≤4W ;

③  220VAC±10% 50HZ;power consumption≤4W                

2.11、working circumstance :

Environment temperature:0~50℃,humidity ≤85%,no corrode and strong electromagnetism disturb;

2.12、Product authentication:

XMT*-808 series temperature meter acquire CE authentication and ROHS Environmental Protection authentication.

Ⅲ、Model selection

Model selection instruction

About XMT*808 series intelligence temperature controller,we mark specific  model on each piece. According to on site control request by itself ,client should contrast the meaning of the product model code carefully before use and choose,to avoid wrong use or wrong model selection.,or you can telephone to consult.
