Product details
- Function Overview:
- Working environment: temperature -10~60 ℃; Humidity ≤ 90% RH, sampling period: 8 times per second; When setting the digital filtering parameter FILt=0, the response time is ≤ 0.5 seconds;
The input adopts a precise and stable digital calibration system, supporting multiple thermocouple and thermistor specifications, with a maximum resolution of 0.1 ℃.
The operation method of humanized design is easy to learn and use.
The anti-interference performance meets the requirements of electromagnetic compatibility (EMC) under harsh industrial conditions.
This instrument adopts maintenance free technology of automatic zero adjustment and digital calibration. If it exceeds the tolerance during metrological verification, it can be corrected by parameters
PID control and upper and lower limit control (positional control) can be manually switched between two modes.

Communication function:
RS485/232 communication, standard MODBUS-RTU protocol. Measurement values can be read through RS485/232, and all parameters of the instrument can be modified. Supports Wincc (Siemens), Mitsubishi, Panasonic, Omron, AB， Configuration King, Asia Control, MCGS (Kunlun Tong State) and domestic PLC equipment
| Can be paired with our company's communication software to display real-time sampling temperature and set values on the computer. And it can record temperature values, generate curves or data reports, and export them as EXCEL documents | Other functions: | The output mode can be switched from automatic mode to manual mode with one click, and the output percentage can be manually adjusted and controlled. | Instrument wiring diagram: |
|---|---|---|---|
| 0 | Built in parameters of the instrument: | serial number | symbol |
| 1 | name | Instructions | SP |
| 2 | set value | Short press the set button for 1 second to modify the set value | AL1 |
| 3 | alarm set value | Please refer to the parameter "ALP" for the alarm method. When the alarm is released, it is AL1-HY1 | HY1 |
| 4 | Alarm return difference | The measured value can be corrected by adding or subtracting this value | SC |
| 5 | Sensor correction value | When errors are caused by measuring sensors, this value can be used to correct them | HY Main control return error |
| 6 | The less sensitive area of the instrument when using positional control mode, the smaller the value, the better the control effect. However, when it is a relay output, frequent jumping affects its service life | P | proportionality factor |
| 7 | The P-value is similar to the proportional band of a conventional PID controller, but the change is opposite. The larger the P-value, the proportional and differential effects increase, while the smaller the P-value, the proportional and differential effects decrease accordingly. The P-parameter value is independent of the integral effect. | When P=0, switch to binary control (upper and lower limit control) | I |
| 8 | integral coefficient | The value of the I parameter mainly determines the integration effect in the adjustment algorithm, similar to the integration time in conventional PID algorithms. The smaller the I value, the stronger the system integration effect, and the larger the I value, the weaker the integration effect. When I=0, the system cancels the integration function and the instrument becomes a PD regulator. | D |
| 9 | differential coefficient | The parameter D has an impact on the proportional, integral, and derivative of the control. The smaller the parameter d, the more proportional and integral effects it has; On the contrary, the larger d, the weaker the proportional and integral effects, while the differential effects are relatively enhanced. In addition, d also affects the performance of overshoot suppression function, and its setting has a significant impact on the control effect. When d ≤ t (control period) is set, the differential effect of the system is cancelled. | T |
| 10 | control cycle | The control cycle when the main controller is an artificial intelligence PID control method and the output is a relay. The shorter the time, the better the control effect, but it will affect the lifespan of the relay. The general factory value relay is set to 20S, while others are set to 2S. | AT |
| 11 | Self setting switch | OFF: Self tuning function turned off ON: Self tuning function turned on Self tuning process, please refer to "7. Self tuning method" | COOL |
| 12 | Positive and negative control | 0: Positive control, such as heating and humidification; 1: Reverse control, such as cooling and dehumidification | ALP |
| 13 | alarm method | '0' has no alarm; '1' upper limit alarm; '2' lower limit alarm; '3' positive deviation alarm; Negative deviation alarm for '4'; Alarm outside the '4' interval; Alarm within the '5' interval | PF |
| 14 | filter coefficient | For the first-order lag filtering coefficient of the instrument, the larger its value, the stronger its resistance to instantaneous interference, but the response speed lags behind. | PS-H |
| 15 | upper range limit | Current and voltage signal display upper limit | PS-L |
| 16 | lower range limit | Current and voltage signal display lower limit | DP |
| 17 | decimal point | decimal place | LOCK |
| 18 | combination lock | When LOC=18, all parameters are allowed to be modified. When LOC ≠ 18, all parameters are prohibited from being modified | UO |
