I. Overview:

TTC-series intelligent temperature controller, with dedicated microprocessor as the main circuit, adopts switching power supply and surface mount technology (SMT), so the instrument is exquisite and compact, and its performance is superior. Its unique self-diagnostic function, self-tuning function and intelligent control function allow the user to obtain good control effects through simple operation.

Second, the main features:

1. Thermocouple, RTD, analog quantity and other signals are freely input, the range is freely set;
2. Software zero adjustment fullness, cold end separate temperature measurement, amplifier self-stabilization, accuracy better than 0.5% FS;
3.Fuzzy theory combined with traditional PID method, the control is fast and stable, the setting method is advanced and precise;
4. Output optional: relay contact, logic level, thyristor zero-crossing output and power supply Output, with two definable alarm contact outputs;
5. The control mode adopts self-tuning PID technology, which has the characteristics of rapid temperature control, fast response, small overshoot and high precision compared with traditional PID control.

Third, the main technical parameters:

measurement accuracy:

±0.5% kFS

Cold junction compensation error:

±2°C (software correction in the range of 0~50°C);



The sampling period:


power supply:


Insulation resistance:

>50MΩ (500VDC);

Dielectric strength:

1500VAC / 1 minute min;;

Power consumption:

<10va;< p="">

Use environment:

0~50°C, 45~85% RH

Fourth, the installation attention to the top:

1. The meter is installed in the following environment: (1) atmospheric pressure: 86~106KPa; (2) ambient temperature: 0~50 °C; (3) relative humidity: 45~85% RH; (4) Storage temperature: -25~+65 °C;

2. Pay attention to the following conditions when installing: condensation caused by sudden changes in ambient humidity; water, oil, chemicals, smoke or vapor pollution; excessive dust, salt Or metal powder; [air conditioning direct blow; direct sunlight;
heat radiation, convergence

Five, order model identification:

(1). The second way alarm type ALM2 (the alarm type is the same as the first way)

(2). The first alarm type (ALM1)1. The alarm is not set. 2 The upper limit deviation report is 3. The lower limit deviation alarm is 4. The upper and lower limit deviation alarms are
5. In-range alarm
6. With standby upper limit deviation alarm
7. With standby lower limit deviation alarm<8>. With standby upper and lower limit deviation alarm<9>upper limit input value report 10. Lower limit input value alarm<11>with standby upper limit input alarm<12>with standby lower limit input alarm

(3) Output mode<1>No output
2. Relay contact output
3. Voltage pulse output (SSR)
4. Thyristor zero-crossing output, input type and range ( See Table 2)

(4) Control mode
